VICTOR Ocean Science Foundation, 4051 Glenwood, Irvine, CA 92604 and Guy Harvey Research Institute, Nova Southeastern University, 8000 North Ocean Drive, Dania Beach, FL 33004 E-mail: ben@coralreefish.com Abstract The following thirty-four new species of the pempherid ish genus Pempheris are described from the western Indian Ocean, raising the total number for the region to 47 species: P. andilana from northwest Madagascar; P. argyrea from the Seychelles; P. bineeshi from southeast India; P. bruggemanni from Réunion and Mauritius; P. connelli from KwaZulu-Natal, South Africa; P. ellipse from the south coast of Oman; P. hadra from the Republic of the Maldives; P. heemstraorum from Rodrigues, Mascarene Islands; P. hollemani from southeast Madagascar; P. ibo from Mozambique and South Africa; P. kruppi from the Gulf of Aden and Socotra; P. kuriamuria from the south coast of Oman; P. leiolepis from Chumbe Island, Zanzibar; P. megalops from the Seychelles; P. micromma from the south coast of Oman; P. muscat from the Gulf of Oman; P. orbis from the Red Sea; P. pathirana from Sri Lanka; P. peza from southern Mozambique; P. rochai from the south coast of Oman; P. rubricauda from northwest Madagascar; P. sergey from the Red Sea; P. shimoni from Kenya; P. shirleen from the Red Sea; P. smithorum from Zanzibar; P. tau from the Red Sea; P. ternay from the Seychelles; P. tilman from the Gulf of Aqaba, Red Sea; P. tiran from the Strait of Tiran, Red Sea; P. trinco from Sri Lanka; P. viridis from the Red Sea; P. wilsoni from the Gulf of Oman; P. xanthomma from the Gulf of Aden (Yemen); and P. zajonzi from the Socotra Archipelago. Many of the new species are described from single specimens or one location, indicating a need for more collecting to resolve the taxonomy of this group: we emphasize that some decisions are tentative and apply to the state of collections at present. The barcode mtDNA COI sequences for 21 of the 47 WIO species are analyzed, showing some deep divergences between species, but also several sibling species or species complexes that apparently share COI sequences. The genetic analysis is also limited by small sample sizes; more extensive genetic surveys are required to conirm the results. An appendix includes the description of the hybrid P. malabarica × P. russellii, a discussion of a complex of Pempheris in St. Brandon’s Shoals in need of further study, and underwater photographs of potential new species of Pempheris for which we have no specimens. Key words: taxonomy, ichthyology, systematics, coral-reef ishes, sweepers, DNA barcoding. 1 Introduction The ish family Pempheridae, with the common name sweepers, consists of two genera, Pempheris Cuvier 1829, with 35 previously described valid species, and Parapriacanthus Steindachner 1870, with ive species (Eschmeyer & Fricke 2015). These ishes are found in all tropical to warm temperate seas, except the eastern Paciic Ocean. They are characterized by a compressed, rhomboid-shaped body; very large eyes; short snout; the dorsal in near the middle of the body, with VI spines and 9 (rarely 10) rays; and a very long, low anal in with III spines and 35–48 rays. They are unusual in having two layers of scales, those of the outer layer larger and very deciduous. These ishes typically form aggregations in caves or below ledges on reefs by day, and emerge from shelter at night to feed near the surface on zooplankton. The South African Institute for Aquatic Biodiversity (SAIAB) will soon publish a series of volumes on all the coastal ishes of the western Indian Ocean (WIO), including the Red Sea and the Persian Gulf. Most of the family accounts have been written by author(s) recognized as authorities of the group. When it was determined that the family Pempheridae needed a more comprehensive review, the irst author, as one of the editors of the SAIAB volumes, volunteered to prepare it. He enlisted the collaboration of the second author for the latter’s expertise on the molecular taxonomy of coral-reef ishes. The family is now the last needed before the volumes can be published. Pempheris is a particularly troublesome genus for taxonomists, since the species’ morphology varies little, their few distinctive markings are frequently shared, their meristics broadly overlap, their outer scales are deciduous, and they are not frequently collected or targeted in surveys. As a result, most of the literature prior to 2013 on the genus for the western Indian Ocean is based on misidentiications. Of the checklists and guidebooks that have been published in the last 30 years that list species of Pempheris of the western Indian Ocean, none have any species of Pempheris correctly identiied. The irst author’s book Coastal Fishes of Oman, published in 1995, will serve as an example. One species of Pempheris is illustrated on page 244 by two color igures identiied as P. vanicolensis. The irst photograph (Fig. 637) is P. convexa, described by the authors in 2014. The second (Fig. 638) is an underwater photograph of a species of Pempheris in the schwenkii complex, clearly not P. vanicolensis (a species known from the Andaman Sea and Paciic Ocean). An additional species is illustrated by Fig. 639, and identiied only as Pempheris sp. It should have been labeled P. malabarica (however, we suspect that more than one species may be presently included in nominal P. malabarica). Our rsearch on the genus began in 2013 with the description of the new Indian Ocean species Pempheris lavicycla, which had long been misidentiied as P. vanicolensis (Randall et al. 2013). For the irst time, mtDNA sequencing was used in Pempheris to assist in differentiating similar-appearing specimens. Subsequently, Mooi & Randall (2014) described P. bexillon from the southwestern Indian Ocean, Randall & Bineesh (2014) clariied the species from India (with one new species), and Randall & Victor (2014) described four new species from Oman and the African coast. The Pempheris species of the Red Sea have also been recently revised: Koeda et al. (2014) described the new species P. tominagai, but then mistakenly listed three other species which do not occur in the Red Sea. Randall et al. (2014) corrected Koeda et al. (2014) and concluded that there were three Red Sea species. This was conirmed by Azzurro et al. (2015), who documented the invasion of the Mediterranean by P. rhomboidea and recorded P. lavicycla and P. tominagai as the two other Red Sea species. Only ive of the now 47 species of Pempheris in the western Indian Ocean (including India and Sri Lanka) were described before 2013 (all before 1889), one was added in 2013, seven were added in 2014, and 34 more are described herein. An appendix includes the description of the hybrid Pempheris malabarica × P. russellii from Pakistan; underwater photographs of unidentiied species of Pempheris from the western Indian Ocean are also shown in the hope that specimens can be collected, including at least eight probable undescribed species of Pempheris represented by underwater photographs taken by Dawn Goebbels in the Watamu Marine National Park, Kenya; and a discussion of a complex of Pempheris in St. Brandon’s Shoals in need of further study. Little is known of the early life history of Pempheris, but their larvae are known to settle at a particularly small size for reef ishes, as small as 6 mm SL (Leis & Carson-Ewart 2000). This correlates with a relatively short larval life and reduced dispersal, which would promote local adaptation and the development of species complexes in areas with widely dispersed reef habitats such as the broad western Indian Ocean region. While checking the sex of specimens of Pempheris, we have noticed mature gonads in ish of surprisingly small size for the species, as well as a very high percentage of ish in spawning condition, indicating year-round spawning. Underwater 2 photographs and our observations of aggregations of Pempheris often reveal more than one species. Pempheris are broadcast spawners, which could facilitate hybridization and a degree of introgression that may slow the divergence of mitochondrial DNA lineages as species complexes evolve. These speculations require additional evidence, but may account for the high diversity in the genus in the western Indian Ocean and the frequent sharing of mitochondrial haplotypes within some species complexes. Many of the species of Pempheris described below are without enough specimens for adequate description (nine from single specimens!), and most without knowledge of the life color. We hope that this publication, admittedly preliminary, will aid in acquiring more material of this troublesome genus. Materials and Methods Few species of ishes have proven more dificult to classify than those of the genus Pempheris. Most are morphologically very similar, the color is often a near-uniform copper, bronze or silver, and the dorsal in is either broadly black-tipped, or the anterior margin black, or both. Of the ins, only the number of anal-in soft rays is of diagnostic value, but the range is broad (Table 1); therefore, many specimens would be needed for this count to have value. The last segmented ray in the dorsal and anal ins is divided at its base: it is counted as a single ray. Counts of pectoral-in rays include the rudimentary upper ray and vary from 16 to 19, usually 17 or 18; they can be of modal value only when many specimens are available. The pectoral-in rays of both sides are counted but presented as separate counts (Table 1). The ins of museum specimens of Pempheris are often damaged, especially the dorsal and caudal ins. Because the large scales of the outer layer are so easily shed, the only viable scale count is that of the more adherent small scales of the lateral line (Table 2); again, many specimens are needed to obtain the deinitive range. The lateral-line of species of Pempheris continues to the end of the caudal in; the lateral-line scales are counted to the base of the caudal in. Occasional lateral-line scales on some specimens were found with two sensory pores. In such cases, the number of scales is counted, not the pores. Scales with two pores usually have two narrow columns of scales above. These double columns are more easily seen than the pores. The species of Pempheris have both ctenoid and cycloid scales. Whether the scales are ctenoid or cycloid, and on what parts of the body they are found, are also of importance for species identiication. All species of the genus have a midventral row of small scales that bear a median ridge, and all have two rows of small, strongly ctenoid scales to each side of the median ventral row. The scales on the side of the chest (deined as above the ventral two rows of scales, below the base of the pectoral in, posterior to the margin of the operculum, and anterior to a line from the rear base of the pectoral ins to the origin of the pelvic ins) may be ctenoid or cycloid, or divided into a ventroanterior ctenoid part and a dorsoposterior cycloid part. This is often of diagnostic importance when all of the scales of the outer layer are present on the side of the chest (too often they are not). All species of Pempheris have ive longitudinal rows of ctenoid scales dorsally on the body posterior to the dorsal in; the lower row on each side is only about half ctenoid. If any part of a scale is ctenoid, it is regarded here as ctenoid. Depending on the species, the scales may be either ctenoid or cycloid on the nape, below the dorsal in, on the mid-side of the caudal peduncle, and on the chest. The caudal peduncle has the highest loss of scales of any part of the body, so one can rarely determine whether the scales on the side of the peduncle are cycloid or ctenoid. Gill-raker counts are important meristic data, in general, but the range is also broad. The counts are divided into the dorsal and ventral parts, with the raker at the angle included in the ventral part. However, only the total count is recorded in the species accounts and Table 3. The low, rounded ventroposterior margin of the preopercle usually has one or two lat triangular spines and thin, lexible, translucent projections of variable shape, some with small holes. There is so much intraspeciic variation with this ridge that we have not used it for species identiication; also it is normally covered by scales. The species of Pempheris have steeply oblique jaws, the edge of the maxilla varying from 59–75° to the horizontal axis of the body. The angle is a useful diagnostic character. It is measured by protractor at the ventral edge of the maxilla with the jaws slightly open. The horizontal axis of the body is taken from the tip of the snout through the center of the eye to a point at the middle of the ventral half of the caudal peduncle. The teeth in the jaws are small, but their features are often important for species identiication. Very small teeth are consistently 3 4 present on the vomer and palatines, but they are of little diagnostic value. All specimens of Pempheris we have examined have a close-set pair of vertically oval nostrils directly anterior to the orbit. Most of the specimens of Pempheris examined for this study are from the ish collections of the Bishop Museum, Honolulu (BPBM); South African Institute for Aquatic Biodiversity, Grahamstown, South Africa (SAIAB); and the United States National Museum of Natural History, Washington, D.C. (USNM). We have also obtained loans from the Natural History Museum, London (BMNH); California Academy of Sciences, San Francisco (CAS); Australian National Fish Collection at Hobart, Tasmania (CSIRO); Hebrew University of Jerusalem (HUJ); King Abdulaziz University Marine Museum, Jeddah (KAUMM); Muséum national d’Histoire naturelle, Paris (MNHN); National Bureau of Fish Genetic Resources, Kochi, India (NBFGR); Natural History Collection of Yemen (NHCY; now curated at SMF); Phuket Marine Biological Centre, Phuket, Thailand (PMBC); Senckenberg Museum, Frankfurt (SMF); Steinhardt Museum of Natural History, Tel Aviv University (SMNHTAU); the Université de La Réunion, St. Denis (URUN); and the Zoological Survey of India, Kozhikod (formerly Calicut), India (ZSI/CLT). Data in parentheses in the descriptions refer to paratypes. Lengths of specimens are given as standard length (SL), measured from the median anterior end of the upper lip to the base of the caudal in (posterior end of hypural plate); head length is measured from the same anterior point to the posterior end of the opercular lap, and upper-jaw length from the same anterior point to the posterior end of the maxilla; body depth is taken from the origin of the anal in vertically to the internal base of the dorsal in (not always the maximum depth); body width is measured just posterior to the opercular lap (used only for adults; juveniles are much thinner); predorsal and prepelvic lengths have proven to be of value as identiication characters, often more important than the length of rays of the ins, because the latter are so often broken on museum specimens, the measurements are taken from the origin of the irst spine to the tip of the upper lip; eye diameter is the horizontal length of the bony orbit; interorbital width the least bony width; lengths of spines and rays of median ins are measured from their extreme base to tip of longest ray; caudal-in length is taken horizontally from the base to a perpendicular at the end of the longest ray, however, most museum specimens have lost enough of this in to prevent taking this measurement, The same is true to a lesser extent for the dorsal in. Pectoral- and pelvic-in lengths are the lengths of the longest ray, taken to the extreme base. The head of ishes of the genus Pempheris is much broader (thickness) than the strongly tapering body. When photographing a specimen, it is necessary to elevate the tail end to have the ish in optimal focus. This results in a shorter snout in the photograph. Measurements of specimens were taken from specimens, not photographs. Proportional measurements are rounded to the nearest 0.05. A small number of the more recently collected specimens have been preserved for DNA sequencing studies, a number clearly inadequate to assess the degree of genetic variation in the genus. DNA extractions were performed with the NucleoSpin96 (Machery-Nagel) kit according to manufacturer speciications under automation with a Biomek NX liquid-handling station (Beckman-Coulter) equipped with a iltration manifold. A 652-bp segment was ampliied from the 5′ region of the mitochondrial COI gene using a variety of primers (Ivanova et al. 2007). PCR ampliications were performed in 12.5 µL volume including 6.25 µL of 10% trehalose, 2 µL of ultra pure water, 1.25 µL of 10 × PCR buffer (10 mmol/L KCl, 10 mmol/L (NH4)2SO4, 20 mmol/L Tris-HCl (pH 8.8), 2 mmol/L MgSO4, 0.1% Triton X-100), 0.625 µL of MgCl2 (50 mmol/L), 0.125 µL of each primer (0.01 mmol/L), 0.0625 µL of each dNTP (10 mmol/L), 0.0625 µL of Taq DNA polymerase (New England Biolabs), and 2 µL of template DNA. The PCR conditions consisted of 94°C for 2 min, 35 cycles of 94°C for 30 s., 52°C for 40 s., and 72°C for 1 min, with a inal extension at 72°C for 10 min. Specimen information and barcode sequence data from this study were compiled using the Barcode of Life Data Systems (Ratnasingham & Hebert 2007). The sequence data is publicly accessible on BOLD and GenBank. Additional sets of comparison COI sequences were obtained from prior studies compiled in GenBank. Sequence divergences were calculated using BOLD with the Kimura 2-parameter (K2P) model generating a mid-point rooted neighbor-joining (NJ) phenogram to provide a graphic representation of the species’ sequence divergence. Mitochondrial DNA lineages obtained in the BOLD database have been assigned code numbers, or BINs (Barcode Index Numbers), to permanently name lineages. BINs are clusters calculated by an algorithm taking into account similarities and connectivity and assessing cluster boundaries. The BINs occupied by the mtDNA lineages for the species that have been sequenced for this paper are presented under the species title after the Figures and Tables. Key to the Species of the Genus Pempheris of the western Indian Ocean 1a.

Mitochondrial DNA sequences can assist in decisions on the taxonomic status of populations, but cannot be used in isolation to decide species status (Victor 2015). Although most reef ish species show monophyletic mtDNA COI lineages more than 2% different from their nearest relatives (Steinke et al. 2009, Ward et al. 2009), there is no clear threshold degree of divergence between the mtDNA lineages of established species. Indeed, many cases of species that share COI sequences (the “barcode” mtDNA marker used in the Barcode of Life project) have been documented, i.e. “phenovariant” species sensu Victor (2015). Two species that are on their own evolutionary trajectories can share mtDNA sequences due to insuficient time since speciation events for mitochondrial mutations to accumulate (incomplete lineage sorting) or some degree of hybridization allowing mitochondrial haplotypes to be traded (via maternal descent, and then taking extensive time to be eliminated by chance). In cases of phenovariant populations, a close look at the morphological, meristic, and marking differences is required to make taxonomic decisions about species status. Where we ind non-overlapping monophyletic sets of haplotypes (i.e. divergent lineages), it conirms that there is some degree of reproductive isolation between populations. This alone does not deine species, and when there are no corresponding morphological, meristic, and marking differences of a “suficient” degree, the populations would be considered “genovariant” populations of the same species (Victor 2015). The inal decision on species status is essentially a taxonomist’s subjective determination. In the case of the western Indian Ocean Pempheris, there is limited information on the genetic structure of populations and species. At present, 21 of the 47 regional species have been barcoded (sequenced for the COI marker), however many are based on single specimens. An additional lineage occurs in South Africa based on a sequence from an egg (P. sp. 1); it may represent one of the many unsequenced species or an additional species. The phenetic tree based on the COI sequences of Indian Ocean populations of Pempheris is presented in Fig. 1. Many species form deeply divergent monophyletic lineages well isolated from their nearest relatives, but some are only minimally divergent lineages, although clearly distinct (e.g. the 1% divergence between the P. rhomboidea complex vs. P. mangula). Several new species described here have sequences only slightly different from their nearest relatives, but, since they are based on single sequences, the consistency of the divergence is untested. Several more new species share identical haplotypes with their closest relatives, but those are also mostly based on single sequences. In general, most phenovariant species documented in this study are allopatric, suggesting that regional species complexes are in the process of diverging. In one case the phenovariants are both from Oman (P. kuriamuria from the south coast of Oman and P. wilsoni from the northern coast in the Gulf of Oman), but this is also based on single sequences and clearly needs to be conirmed. The P. rhomboidea species complex appears to be the largest complex of phenovariant species documented to date, with six putative species in the region mostly sharing haplotypes (and many more unsequenced) and ranging from the Red Sea (and invasive in the Mediterranean), south to South Africa, and eastward to Pakistan. The six sequenced phenovariants are mostly allopatric, but several species in the complex occupy the coastline from Yemen to Oman; unfortunately these species are among the least well documented and this area is now one of the more dificult places to work on the globe. The true P. schwenkii complex (excluding the distantly related “schwenkioid” species, most of which are from the southwestern Indian Ocean) is another group that contains sets of phenovariant species, falling into two distinctly divergent sets of species that either share haplotypes (P. bineeshi/hadra/schwenkii) or are fractionally different (P. tominagai/xanthomma/ternay/rubricauda). The true P. schwenkii complex in the Indian Ocean is entirely allopatric, with the larger genetic split between the far western Indian Ocean species and the central/eastern species, i.e. from Maldives, India, to Indonesia. It is unclear what exactly is the origin and signiicance of these shared lineages in Pempheris; it is an unusual inding among tropical marine reef ishes that needs to be further explored. One could speculate that it may be a result of an increased opportunity for accidental hybridization among crepuscular or nocturnal groupspawning ishes, or something to do with the presumably short larval duration of Pempheris facilitating regional differentiation, but not complete enough to develop corresponding genetic structure. Clearly, much more information on the genetics of this particularly dificult genus is needed. Figure 1 (opposite).

This species is named Pempheris andilana for the beach on the island of Nosy Be, NW Madagascar, adjacent to the reef from which the type specimens were collected. The speciic epithet is a noun in apposition. Remarks. This new species is one of the large group of species of Pempheris that we term the schwenkii complex, named for the irst species, P. schwenkii Bleeker, that was described from the Batu Islands off the SW coast of Sumatra in 1855. The last twenty-ive species in the above key are from this group. They tend to be more slender, on average, than the remaining species of Pempheris, and all have a broad, dark brown to black band at the base of the anal in, as well as a dark brown to black anterior margin on the dorsal in that, on some species, expands to a dark distal spot. Also they lack the lateral dark stripes on the lanks made up of darkened scale centers characteristic of the rhomboidea complex of species. Two other members of the schwenkii complex are known from Madagascar: P. rubricauda from the same region as P. andilana and P. hollemani from the SE of the island: both differ in having a shorter predorsal length. No DNA sequences are available for P. andilana. Pempheris argyrea Randall & Victor, n. sp. Figures 3 & 4, Tables 1–3. Pempheris schwenkii [non Bleeker] Randall & Bineesh 2014: 37. Holotype.

Color when fresh as in Fig. 3. Etymology. This species is named Pempheris argyrea, from Greek for silvery, in reference to its overall silvery coloration, as noted when irst collected and photographed as a specimen. Remarks. This species has been observed and collected only from the three main islands of the Seychelles, Figure 4. Pempheris argyrea, aggregation, La Digue, Seychelles (J.E. Randall). 19 with La Digue selected as the type locality. It is typically seen by day in aggregations in the shelter of coral reefs, at times in less than 1 m. One of 25 species of the broad schwenkii complex presently conirmed for the western Indian Ocean, distinguished by relatively large eyes, low count of 36–40 anal-in soft rays, modally 17 pectoralin rays, 26–30 gill rakers, small size (largest specimen, the holotype, 102 mm SL), and silvery coloration. P. ternay, the other member of the schwenkii complex from the Seychelles, is distinguished by a black-bordered bright red-orange caudal in. Two non-schwenkii complex species also occur in Seychelles: P. lavicycla and P. megalops. No DNA sequences are available for P. argyrea. Pempheris bineeshi Randall & Victor, n. sp.

Color when fresh as in Fig. 6. Etymology. This species is named for K.K. Bineesh of the ICAR-National Bureau of Fish Genetic Resources (NBFGR) in Kochi, Kerala, in recognition of the extensive efforts he has made to collect, photograph, and DNAbarcode species of Pempheris in India. Remarks. Presently known only from the type location, but to be expected elsewhere in SE India, and maybe well beyond. All of our specimens have been obtained from ishermen in Tuticorin, one of the oldest cities of India. The sweepers are typically collected as bycatch on small trawlers that ish in the evening and at night off the coast; the objective is shrimp and ishes of far more value than the small, thin-bodied species of Pempheris. Specimens collected by trawling have always lost nearly all of their scales. P. bineeshi is the only representative of the schwenkii complex from Indian waters, although P. trinco is described from nearby Sri Lanka. Other congeners from south India include P. malabarica, P. mangula, and P. sarayu. The barcode mtDNA COI sequences of P. bineeshi are the same as the sequence from P. hadra from the Maldives well to the south and specimens of presumed true P. schwenkii from Bali, Indonesia (the type location of P. schwenkii is Sumatra, midway between the Indian subcontinent and Bali). The three species form a lineage 3.4% divergent from a set of schwenkiicomplex species from the western Indian Ocean, i.e. P. tominagai from the Red Sea, P. xanthomma from Yemen, P. ternay from Seychelles, and P. rubricauda from Madagascar (Fig. 1). 21 Pempheris bruggemanni Randall & Victor, n. sp.

This species is named for Professor Henrich Bruggemann of the Laboratoire d’Ecologie Marine, Université de la Réunion, who collected the type specimens with N. Hubert and S. Planes and provided the photographs. He was supported by the BIOTAS program of the French Agence Nationale de Recherche (ANR06-BDIV), with the collaboration of Gustav Paulay (Florida Museum of Natural History). Figure 7. Pempheris bruggemanni, holotype, MNHN 2015-002, male, 108 mm SL, Réunion (H. Bruggemann). 22 Figure 8. Pempheris bruggemanni, paratype, URUN 2007-1419, female, 97 mm SL, Réunion (H. Bruggemann). Remarks. Presently known only from Réunion and Mauritius. The head of the holotype of P. bruggemanni must have been bent inwardly when photographed, resulting in an unnaturally short snout (a distortion also noted in some photographs of other species of the genus). The 83-mm male and 86.5-mm female paratypes are sexually mature. The paratype from Mauritius is in poor condition and was not used for measurements. Prof. Bruggemann conirms our identiication of Alain Diringer’s underwater photograph of Fig. 9 as the subadult of the present species. One other member of the schwenkii complex, P. heemstraorum, has also been collected in the Mascarene Islands, a single specimen from Rodrigues: it is a larger ish with a deeper body than the present species. The barcode mtDNA COI sequences of P. bruggemanni form a lineage 6.5% divergent (K2P; 6.3% uncorrected pairwise) from their nearest relatives, the clade including the common P. connelli of South Africa as well as P. hollemani from Madagascar and P. rochai from Oman (Fig. 1).

Color when fresh as in Fig. 10; no black spot at base of pectoral ins, but a narrow, curved dark brown line at base of pectoral-in rays (not crossing entire base); axil of pectoral ins dark brown to black; no black posterior border on caudal in; color in life as in Fig. 11. Largest specimen examined, 126.5 mm SL. Etymology. This species is named for Dr. Allan D. Connell, whose untiring efforts to document the ishes of KwaZulu-Natal have resulted in the discovery of many new species. He collected several of the recent lots of the types of this species, as well as numerous specimens, photographs, and tissue samples of other species of ishes from southern Africa. Remarks. Presently known only from KwaZulu-Natal, South Africa. A second member of the schwenkii complex, P. ibo, occurs in South Africa and Mozambique and can be found on the same reef and in the same collections as P. connelli. Dr. Connell speared one of each species in 24 m at Aliwal Shoal. The two species are easily confused as preserved specimens, but can be fully separated by the lateral-line scale count: 50–58 for P. connelli vs. 43–49 for P. ibo. Also P. connelli appears to attain larger size; the largest of 14 specimens of P. ibo examined by us measures 93 mm SL. Fortunately, despite their outward similarity, the barcode mtDNA COI sequences of the two species are very different: P. connelli sequences are 13.3% divergent (K2P; 12% uncorrected pairwise) from P. ibo. In fact, P. bruggemanni from the Mascarene Islands are actually closer genetically to P. connelli (6.3% divergent) and are the nearest-neighbor lineage (Fig. 1). The barcode sequence from the type specimens of P. hollemani from Madagascar and P. rochai from Oman have the same COI sequence as P. connelli, indicating either a recent split of closely related species or occasional hybridization may occur between the three species across the western Indian Ocean.

Dorsal-in rays VI,9; anal-in rays III,39 (36–40); pectoral-in rays 18 (17–19, strongly modal 18; only one count of 19); lateral-line scales 53 (50–57); lateral line very strongly arched anteriorly, rising 3/4 orbit diameter above level of origin of lateral line; scales on nape and below dorsal in ctenoid; scales on ventroanterior third of side of chest ctenoid, remaining chest scales cycloid; most scales missing from caudal peduncle, but the few intact scales are cycloid; gill rakers 27 (26–30); body deep, the depth 2.1 in SL, and moderately thick, the width 2.95 in depth; head length 3.35 in SL; eye forming a vertical ellipse (bony orbit width 12.2 mm; bony orbit height 13.9 mm); orbit diameter 7.45 in SL; interorbital width 10.9 in SL; jaws steeply oblique, the edge of maxilla forming an angle of 70° (69–75° in juveniles) to horizontal axis of body; upper jaw with a close-set, double row of small, recurved, sharply conical teeth that are progressively smaller laterally, ending in a single row of very small nodular teeth; band of teeth medially in lower jaw crossed by four to six irregular rows of very small recurved teeth, not clearly larger inwardly; tongue narrowly triangular with pointed tip; predorsal length 2.8 in SL; longest dorsal-in ray 3.75 in SL; caudal in broken; pectoral-in length 3.3 in SL; prepelvic length 2.65 in SL; pelvic ins reaching origin of anal in, their length 5.65 in SL. Color of holotype in alcohol as shown in Fig. 12; the body is uniform brown, only the scale edges a little lighter, except for a reddish hue on the chest and a faint greenish zone beneath the pectoral in and continuing ventrally to the pelvic ins. Color of a juvenile in alcohol as in Fig. 13. Life color not reported. Etymology. This species is named Pempheris ellipse in reference to the longer vertical axis of the orbit, giving the eye an elliptical shape. The speciic epithet is a noun in apposition. Figure 12. Pempheris ellipse, holotype, BPBM 35867, female, 93 mm SL, Rahah Bay, south coast of Oman, with two spear wounds on side below dorsal in (H.A. Randall). 26 Figure 13. Pempheris ellipse, paratype, juvenile, 41 mm, Rahah Bay, southern Oman (H.A. Randall). Remarks. Fifteen juveniles collected from a tidepool at Rahah Bay were identiied as this species by the shape of the eye, the highly arched anterior end of the lateral line, the very steep angle of the upper jaw, and meristic characters. Three other species of Pempheris were collected in the bay: P. convexa Randall & Victor 2014, P. micromma, described in the present paper, and a subadult of an unidentiied schwenkioid species collected from a cave in 14 m (BPBM 36325, 72 mm SL), for which no photograph or color note was taken. It has a very steep jaw angle, straight dorsal proile of the head and nape, ctenoid scales on the nape and below the dorsal in (all scales missing from chest), but differs from P. ellipse in that the eye is round, the body more slender, and the anal in has a blackish margin. Pempheris rochai, described herein from the nearby coast of Oman, might also be expected in the bay. A photograph of the tidal channels of Rahah Bay was published by Randall & Victor (2014: Fig. 2).

Dorsal-in rays VI,9; anal-in rays III,38; pectoral-in rays 17; lateral-line scales 49; gill rakers 26; body depth 2.45 in SL; body very stout, the width (taken just behind gill opening) 2.2 in body depth; head length 3.5 in SL; eye relatively small, orbit diameter 8.4 in SL; interorbital width 12.5 in SL; mouth oblique, forming an angle of 64° to horizontal axis of body; tip of lower jaw slightly anterior to upper jaw when mouth fully closed; teeth in upper jaw in two well-separated rows medially, narrowing to a single row posteriorly; conical teeth medially in lower jaw in four or ive densely packed rows, those of outer row nearly erect, the remaining teeth progressively more recurved inwardly; scales on nape and below dorsal in cycloid; scales on ventroanterior two-ifths of chest and along edge of operculum ctenoid, cycloid on the remaining three-ifths; scales on caudal peduncle ctenoid; predorsal length 2.7 in SL; longest dorsal-in ray 3.95 in SL; caudal in emarginate, the caudal 27 Figure 14.

Color in alcohol dark orangish brown, the scale edges narrowly pale yellow; ins yellowish, the leading edge of dorsal in blackish, expanding into a large black apical spot; dark reddish streaks following longitudinal scale rows below lateral line: anal in with a very dark brown band at base, 3 times broader anteriorly (comparable to the width of the in); a middorsal V-shaped blackish mark on nape before dorsal in; caudal in with a broad blackish posterior margin, the upper and lower margins only slightly darker; no black spot on base or axil of pectoral ins, but a curving dark brown line following base of rays. Color when fresh as shown by Fig. 14. Etymology. This species is named Pempheris hadra, from Greek for thick or stout, in reference to the unusual stocky body. Remarks. We are aware of only a single specimen of Pempheris hadra. It is distinct in being more stoutbodied than any schwenkii-complex species we have examined, and unusual in having cycloid scales on the nape, but ctenoid scales on the side of the caudal peduncle. The unusual habitat is a pool constructed in the lagoon of Kaafu Atoll from which water is taken for cooling the electric power plant. The pool is also used for recreational swimming by the locals. We suspect that this ish found shelter in the incurrent cooling pipe (as have two other species of Pempheris we have documented in Guam). This species is the only schwenkii-complex species collected in Maldives; two unrelated species, P. convexa and P. lavicycla, are the other species known from the archipelago. The barcode mtDNA COI sequence of P. hadra is the same as a lineage of Pempheris that includes P. bineeshi from India and the probable true P. schwenkii (type location Sumatra) from Bali, Indonesia (Fig. 1). The lineage is 3.4% divergent from the nearest lineage in the neighbor-joining tree, which contains the western Indian Ocean complex of P. tominagai from the Red Sea, P. xanthomma from Yemen, P. rubricauda from Madagascar, and P. ternay from Seychelles. 28 Pempheris heemstraorum Randall & Victor, n. sp.

Stapely, Oct. 8, 200l. Description. Dorsal-in rays VI,9; anal-in rays III,37; pectoral-in rays 18; lateral-line scales 59; gill rakers 31; body depth 2.2 in SL; body width 3.35 in body depth; head length 3.05 in SL; eye relatively small, the orbit diameter 8.45 in SL; interorbital width 10.7 in SL; mouth oblique, forming an angle of 63° to horizontal axis of body; tip of lower jaw slightly projecting when mouth fully closed; teeth anteriorly in upper jaw recurved, in two rows medially, reduced to an irregular single row of progressively smaller teeth about one-third back in jaw; teeth of lower jaw very small, conical and recurved, in a dense band of ive to six rows medially, progressively more retrorse inwardly; upper lip with dense papillae; lower lip with small well-separated papillae; tongue narrowly triangular; outer layer of scales missing from nape, side of chest, and caudal peduncle; predorsal length 2.45 in SL; longest dorsal-in ray 3.85 in SL; caudal in slightly forked, caudal concavity about 5 in head length; pectoral ins long, 3.0 in SL; prepelvic length 2.5 in SL; pelvic ins long, reaching origin of anal in, 5.3 in SL. Color in alcohol of body below lateral line nearly uniform light brown, the scale edges a little paler; head and body above lateral line darker brown; dorsal in translucent with dusky rays, the spinous portion and irst ray dark brown, with a little dark pigment extending onto distal end of next few rays; anal in with a dark brown band at base, half depth of in anteriorly, but narrowing posteriorly to only one-ifth height of in; caudal in with translucent yellowish membranes and light brown rays, the upper and lower margins dark brown, a narrow brown band following lateral line to end of in, no posterior dark margin; paired ins pale yellowish, the pectoral ins without a dark brown spot on base or axil. Color when fresh as shown in Fig. 15. Etymology. This species is named for Dr. Phillip C. Heemstra and Elaine Heemstra of the South African Institute for Aquatic Biodiversity, in recognition of their extensive body of work in ichthyology. They collected and photographed the holotype of this species, along with providing many other specimens and photographs of western Indian Ocean ishes. Remarks. This species is unusually large for the schwenkii complex, although the markings are typical for the complex. Three other species are found in the Mascarenes: another schwenkii-complex species, P. bruggemanni, which has more anal-in rays and fewer gill-rakers, and the rhomboidea-complex species P. nesogallica, which was described from Mauritius, and the unrelated P. bexillon. No DNA sequences are available for P. heemstraorum. Figure 15. Pempheris heemstraorum, holotype, SAIAB 69487, 127 mm SL, Rodrigues, Mascarene Islands (P.C.

Color in alcohol pale brown, the head and body above lateral line a little darker; dorsal in with dense melanophores anteriorly and distally; caudal in with ine melanophores on rays, fewer on membranes, the margins of in a little darker; a broad dark band at base of anal in, as if stippled with large melanophores; a curved blackish line at base of pectoral-in rays, and a large black spot in axil of ins. Color when fresh as in Fig. 16. Etymology. This species is named for Dr. Wouter Holleman of the South African Institute for Aquatic Biodiversity, in recognition of his extensive research on western Indian Ocean ichthyology. He provided the data on this species from the two type specimens when they could not be sent on loan. Remarks. The two specimens of P. hollemani were collected during the Atimo Vatae Expedition to southern Madagascar (Philippe Bouchet of the Museum national d’Histoire naturelle, Principal Investigator). Koeda et al. (2014: 317) erred by including this species as a paratype of their new species P. tominagai, type locality Sharm Figure 16. Pempheris hollemani, holotype, SAIAB 200564, 118 mm, SE Madagascar (E. Heemstra). 30 el-Sheikh, northern Red Sea. The specimens are clearly not P. tominagai, a Red Sea species with a different color pattern and more than 15% different mtDNA sequences (Randall et al. 2014). All species of Pempheris of the schwenkii complex share a broad dark brown to black band at the base of the anal in. Pempheris hollemani has this dark anal-in band, but instead of being uniformly dark brown or black, it is unique in consisting of discrete black dots of variable size. The barcode mtDNA COI sequence of P. hollemani is the same as P. connelli from South Africa and P. rochai from Oman, indicating either a recent split of closely related species or some degree of gene low across the western Indian Ocean between the three species (Fig. 1).

Color in alcohol of holotype shown in Fig. 17. The faint blackish border on the anal in is not shared by all specimens. The life color is variable, as shown in Fig. 18. Etymology. This species is named for the type locality, Ibo Island, Mozambique. The speciic epithet is a noun in apposition. Remarks. The 34-m lighthouse at Ibo Island, Pinda, Mozambique was erected in 1923 to warn mariners of nearby shoal waters. Fifty years later, Margaret M. Smith and Robin Stobbs made a small collection of ishes off the lighthouse that included 11 specimens of Pempheris. Ten were identiied as P. adusta Bleeker, later corrected by us to P. eatoni Randall & Victor. The remaining 93-mm specimen is the holotype of the present species. Ten days later, Smith & Stobbs made an inshore ish collection at Quilalea Island, Mozambique that included eight juveniles of P. ibo. Recent collections have extended the range to KwaZulu-Natal, the most southern at Aliwal Shoal, where P. ibo can be found in the same collections as their similar-appearing and more abundant relative, P. connelli. The small size, slender body, meristic data, broad blackish band at base of anal in, and dark leading edge of the dorsal in identify this species as one of the schwenkii complex. It is readily identiied as a distinct species by having 43–49 lateral-line scales (lowest for any species of the genus in the western Indian Ocean– see Table 2), steeply angular anterior lateral line, relatively low count of anal-in soft rays, long pectoral ins, and short predorsal length. The ish of Fig. 18 are readily identiied as P. ibo by the slender body, relatively small eye, angular anterior lateral-line, long pectoral ins, and especially by being able to count the low number of anal-in soft rays and lateral-line scales. One other species of the schwenkii complex, P. peza, has been collected in Mozambique and one other in South Africa, the common P. connelli; both have many more lateral-line scales. Despite the similarity in appearance, the barcode mtDNA COI sequences of P. ibo are very different from the P. connelli lineage, 13.3% divergent (K2P; 12% uncorrected pairwise). The nearest-neighbor lineage to P. ibo is P. bruggemanni from the Mascarenes, but still far distant with 11.8% divergence (K2P; 11% uncorrected pairwise)(Fig. 1). Figure 18.

Largest specimen examined, the holotype. Etymology. This species is named for Dr. Fareed Krupp of the Forschungsinstitut Senckenberg, authority on the ishes of the Gulf of Aden and Red Sea, and principal collector of the irst series of type specimens of the species. Remarks. Presently known only from the Gulf of Aden off Yemen and from the islands of the Socotra Archipelago. It is one of several species in the rhomboidea complex in the region, and is closely related to P. pathirana from Sri Lanka, from which it primarily differs by tooth arrangement. Pempheris rhomboidea from the adjacent Red Sea and P. kuriamuria from Oman have longer pectoral ins; P. darvelli from Oman has a longer head length; P. wilsoni from Oman has a shorter head and prepelvic length; P. muscat, also from Oman, has divided scale types on the chest (vs. entirely ctenoid); and P. russellii from Pakistan has a different shape of the tongue. Moteah Shaikh Aideed earned a coauthor role for the description of this species by providing specimens, collection data, tissue samples, and photographs. The barcode mtDNA COI sequences of P. kruppi from Yemen are the same as others of the rhomboidea complex, including two species described from specimens from nearby Oman: P. kuriamuria and P. wilsoni (Fig. 1). 34 Pempheris kuriamuria Randall & Victor, n. sp.

Darvell & K.D.P. Wilson, Nov. 27, 2013. Description. Dorsal-in rays VI,9; anal-in rays III,40 (38); pectoral-in rays 18 (one side 19); lateral-line scales 61 (59); scales on nape and side of chest ctenoid, mixed cycloid and ctenoid below dorsal in, and cycloid on side of caudal peduncle; gill rakers 30; body depth 2.15 in SL; body width 2.95 (2.85) in body depth; head length 3.3 (3.35) in SL; eye relatively small, equal to postorbital length, the orbit diameter 7.45 (7.3) in SL; interorbital width 12.4 (10.4) in SL; mouth forming an angle of 66° (69°) to horizontal axis of body; upper jaw with small, slender, recurved, conical teeth in two close-set rows to below nostrils, continuing as a single row to end of jaw; teeth in lower jaw in a narrow band, crossed where broadest by six or seven rows of extremely small, recurved, conical teeth that are progressively more retrorse posteriorly; tongue narrowly triangular with slightly incurved sides; predorsal length 2.45 (2.55) in SL; longest dorsal-in ray 3.75 (3.65) in SL; caudal in slightly forked, 3.6 in SL in paratype, caudal concavity about 3.5 in HL (estimated, longest rays broken); pectoral-in length 2.9 (2.95) in SL; prepelvic length 2.5 in SL; pelvic ins just reaching origin of anal in, 5.65 (5.2) in SL. Color in alcohol (Fig. 21) with dark band at base of anal in (very broad anteriorly and progressively narrower posteriorly), broad translucent light middle zone of in, densely stippled with dark brown, and a narrow transparent outer margin; a curved dark purplish brown band at base of pectoral ins; and dorsal in with a black apical spot, no dark leading edge, and a narrow black band at base. Color in life as shown in Fig. 22. Etymology. This species is named for the type locality, the Kuriamuria Islands off the south coast of Oman. The speciic epithet is a noun in apposition. Remarks. The underwater photographs of Fig. 22 are identiied as P. kuriamuria by the long pectoral ins, eye size (equal to postorbital head), body and in proportions, lateral-line scale count, and color pattern, especially the dark brown band at the base of the anal in that narrows posteriorly. Although this band is a typical feature of the schwenkii complex, P. kuriamuria has the stripes along the lank following the scale rows typical of the rhomboidea-complex. The holotype is notable for the relatively long pectoral ins distinguishing it from the other species in the complex (shared only with P. rhomboidea of the Red Sea which differs by having two scale types on the chest vs. all ctenoid). The barcode mtDNA COI sequence of P. kuriamuria is the same as others of the rhomboidea complex, including P. wilsoni, also from Oman (Fig. 1). Figure 21.

Dorsal-in rays VI,9; anal-in rays III,37; pectoral-in rays 18; lateral-line scales 53; scales on nape, below dorsal in, and side of caudal peduncle cycloid; scales on side of chest cycloid, except for two or three ventral ctenoid scales adjacent to operculum; gill rakers 28; body depth 2.4 in SL; body moderately compressed, the width 2.6 in body depth; head length 3.0 in SL; dorsal proile of head nearly straight; eye diameter 7.75 in SL; interorbital width 11.6 in SL; mouth oblique, forming an angle of about 63° to horizontal axis of body; teeth in upper jaw typical of those of lower jaw of the genus, with three or four irregular rows of small conical teeth that are progressively larger and more recurved posteriorly; teeth of lower jaw much smaller and more densely packed, in a maximum of approximately six rows; tip of lower jaw expanded to a small knob that projects slightly forward when mouth irmly closed; tongue triangular with slightly indented sides, the tip rounded and very lexible; predorsal length 2.5 in SL; outer part of dorsal and caudal ins broken; pectoral-in length 3.15 in SL; prepelvic length 2.4 in SL; pelvic ins just reaching origin of anal in, their length 6.2 in SL. Color in alcohol as shown in Fig. 23; the body is a nearly uniform orangish brown, except for a reddish hue to the chest and a greenish zone beneath the basal part of the pectoral in, continuing to the base of pelvic ins; note the absence of a prominent dark spot at the base of the pectoral ins (instead there is a blackish line that nearly crosses the upper part of the in base). Color in life unknown. Etymology. This species is named Pempheris leiolepis, from the Greek meaning smooth scales, in reference to its having the greatest cover of the body in cycloid scales. Remarks. The type locality, Chumbe, is a 16-acre, privately-owned island 8 miles SW of Zanzibar, famous for its spectacular coral reefs. Details are lacking for the Smiths’ collection of our single specimen. The species is a member of the schwenkii complex; it is the only species of the complex we have examined along the African coast north of Mozambique, where there are two other species, P. ibo and P. peza. The upper-jaw dentition is very similar to that of P. andilana and P. argyrea, the basis for grouping them in the same part of the identiication key. No DNA sequences are available for P. leiolepis.

Dorsal-in rays VI,9; anal-in rays III,42; pectoral-in rays 17; lateral-line scales 58; outer layer of scales on nape and side of caudal peduncle missing; scales on about ventroanterior half of side of chest ctenoid, those on remaining half cycloid; gill rakers 31; body depth 2.35 in SL; body width 2.9 in body depth; head length 2.95 in SL; eye extremely large, the orbit diameter 6.2 in SL; interorbital width 11.0 in SL; upper jaw with a narrow symphyseal gap, the larger teeth sharply conical and recurved, mainly in two irregular rows, those of the upper row more jutting, narrowing to a single irregular row nearly half way to end of jaw; very small recurved teeth above and interspersed among larger teeth; lower jaw with a band of very small, nodular, recurved teeth in four or ive irregular rows where broadest medially; predorsal and prepelvic lengths 2.4 in SL; longest dorsal-in ray 3.35 in SL; caudal in damaged; pectoral-in length 3.0 in SL; pelvic ins just reaching origin of anal in, 5.8 in SL. Color in alcohol as in Fig. 24; the caudal in had a broad blackish posterior margin in life, as well as one on the outer margin of anal in, though not as strongly developed. There is no dark spot at the base or axil of the pectoral ins. Color in life unknown. Etymology. The species is named Pempheris megalops from the Greek meaning large eye, in reference to the type having the largest eye of any species of the genus that we have examined. Remarks. This species is apparently not a member of the schwenkii complex, but its placement is uncertain. Three other Pempheris species are found in Seychelles: two in the schwenkii complex, P. ternay and P. argyrea (type specimens of the latter in the same collection as this holotype), and the unrelated P. lavicycla. Pempheris species typically occur in aggregations, so more than one specimen was probably collected in the rotenone station that resulted in the holotype of P. megalops. Not realizing the species was undescribed, only one specimen was preserved, and no photograph was taken. It is odd that this species, with such a large eye, was found by day at a depth of less than one meter. No DNA sequences are available for P. megalops. Figure 24.

The holotype was collected from a large tidal channel in Rahah Bay on the south coast of Oman, along with 15 juveniles of what was believed to be the same species. However, the juveniles were later identiied, chiely by meristics, to be the same as an adult specimen of P. ellipse speared in the bay at a depth of 8 m. The species of the underwater photograph of Fig. 26 is identiied as P. micromma by the very small eye, steep angle of the upper jaw, predorsal and prepelvic lengths, and by the locality of the south coast of Oman near Rahah Bay. The eye of the holotype in Fig. 25 appears vertically elliptical, but this is a result of the head not being in the same plane as the body for the photograph. The left eye measures only 0.5 mm higher than broad, and the right eye is a Figure 25. Pempheris micromma, holotype, BPBM 41157, female, 117 mm, Rahah Bay, southern Oman (H.A. Randall). 39 Figure 26. Pempheris micromma, underwater aggregation, south coast of Oman (J.E. Randall). perfect circle, clearly distinguishing this species from P. ellipse. The holotype does not have the dark band at the base of the anal in characteristic of the schwenkii complex, but the appearance in the underwater photograph is consistent with schwenkii-complex sweepers. Additional material will resolve the status of this species. Two other species co-occur in Rahah Bay with P. micromma: P. ellipse, distinguished by elliptical eyes and a highly arched anterior lateral line, and P. convexa, diagnosed chiely by having a pronounced convex head proile and by lacking a dark brown band at the base of the anal in. Pempheris rochai, described from one specimen from Ras Hamar, nearby on the southern coastline of Oman, might be expected from the bay. It differs markedly by having relatively large eyes, only a single row of teeth medially in the upper jaw, and the unusual count of 10 dorsal-in soft rays. A photograph of the tidal channels of Rahah Bay was published by Randall & Victor (2014: Fig. 2). No DNA sequences are available for P. micromma. Pempheris muscat Randall & Victor, n. sp.

Pempheris muscat, holotype, BPBM 35845, male, 127 mm SL, Cat Island, Gulf of Oman (H.A. Randall). Description. Dorsal-in rays VI,9 (one of six with VI,10); anal-in rays III,40 (35–40); pectoral-in rays 18 (17–19); lateral-line scales 59 (54–59); outer layer of scales on nape and side of caudal peduncle missing; scales ctenoid on about ventroanterior half of side of chest, those remaining cycloid; gill rakers 31 (30–32); body depth 2.35 (2.2–2.35) in SL; body width 2.95 (2.9–3.5) in body depth; head length 3.15 (3.1–3.25) in SL; eye large, orbit diameter 6.85 (6.8–7.4) in SL; interorbital width 11.7 (11.1–12.4) in SL; jaws moderately oblique, the edge of maxilla an angle of 65° (63–68°) to horizontal axis of body; upper jaw dentition similar to that of the generic lower jaw, with a band of 3 to 5 irregular rows of very small, recurved, sharply conical teeth, progressively more sessile inwardly, gradually narrowing posteriorly to side of jaw to a short single row of very small nodules; lower jaw dentition similar to that of upper jaw, the teeth more widely spaced; predorsal and prepelvic lengths 2.5 (2.45–2.55) in SL; longest dorsal and caudal rays broken; longest pectoral ray in paratype with intact in 3.15 in SL; pelvic ins just reaching anus, 6.8 (6.0) in SL. Color of holotype in alcohol as in Fig. 27, the scales of body gray-brown, each with a vertically elongate orange-brown bar stippled with dark brown dots; dorsal in with apical black spot, a narrow dark brown band at base, but no darker leading margin; caudal in with a blackish posterior margin, judging from black pigmentation midposteriorly on remaining in; anal in densely stippled with dark brown, darkest anteriorly, except for translucent whitish margin; paired ins pale orangish, the pectoral ins with a faint narrow dark bar across base of rays. Color in life unknown. Etymology. This species is named for the port city of Muscat, the capital of Oman, the only locality given for the irst museum collection of the species. The speciic epithet is a noun in apposition. Remarks. Pempheris muscat has as few as 35 anal-in soft rays, the lowest count for the genus in the region, shared only with two species in the schwenkii complex, of which the new species is apparently not a member. The appearance broadly overlaps other rhomboidea-complex species, including P. russellii Day, a species from the Sind coast of Pakistan, which was our initial identiication for these specimens until the dentition was closely examined. The teeth at the front of the lower jaw of P. muscat are twice as large as those of P. russellii, well spaced, and in regular rows; those of the upper jaw are unique in the genus in being essentially the same as the teeth of the lower jaw. Further comparison revealed that the new species has a larger head, less body depth, and, if specimens of equal size are compared, a larger eye than P. russellii. No DNA sequences are available for P. muscat. 41 Pempheris orbis Randall & Victor, n. sp. Figure 28, Tables 1–3. Holotype. SMNHTAU P.5284, female, 85 mm SL, Red Sea, Gulf of Aqaba, Dahab, L.

Scales below the lateral line of the largest paratype with light golden centers and orange margins, brightest in pectoral region; dorsal in with black membranes distally between last three spines and irst four soft rays; broad anterior margin of dorsal in darker than rest of in, except distal black part of in. Color in life unknown. Etymology. This species is named orbis, Latin for circle or ring, for the most striking color feature of this species in alcohol (and presumably also in life), i.e. the bright copper ring around the pupil of the eye. The speciic epithet is a noun in apposition. Remarks. No information is available on the habitat of this species; the collectors of the holotype and paratypes are deceased. Evidently a small species; the smallest paratype is a fully mature female. One of seven schwenkii complex species in the Red Sea, distinguished by high lateral-line scale counts, along with more than two rows of teeth medially in the upper jaw, a wide dark band at the base of the anal in, and the copper ring around the pupil.

Color in alcohol as in Fig. 29; note the absence of black pigment at the base of the pectoral ins (also lacking in axil), no black on base or margin of anal in, and black pigmentation forming a spot only distally on the dorsal in. Color in life unknown. Etymology. This species is named for Yohan Pathirana of Aquamarines International in Sri Lanka, who has provided specimens and photographs of Pempheris from the island nation. He also had his divers search for P. pathirana at Trincomalee, where it was collected in 1969 and 1970, but they failed to ind it. Figure 29. Pempheris pathirana, holotype, USNM 432500, male, 129 mm, Trincomalee District, Sri Lanka (S. O’Hara). 43 Remarks. Pempheris pathirana is presently known only from Sri Lanka, but it might be expected in suitable shallow reef habitat in southern India. Specimens from the 1969 and 1970 collections of this species from Sri Lanka in the U.S. National Museum of Natural History were irst identiied as Pempheris nesogallica Cuvier in C. & V. The two species appear very similar as preserved specimens. Pempheris nesogallica was described from the Mascarene Islands and was recently found in KwaZulu-Natal. It has slightly longer predorsal and prepelvic lengths (2.55–2.65 vs. 2.6–2.7 in P. pathirana); slightly longer pectoral ins (3.05–3.2 in SL vs. 3.15–3.3 in P. pathirana); ctenoid vs. cycloid scales on side of caudal peduncle; a few cycloid scales above ctenoid scales on side of chest of P. nesogallica (vs. all ctenoid on P. pathirana); a large black spot on base and axil of pectoral ins of P. nesogallica (at most dark brown on P. pathirana); and 30–34 gill rakers for P. nesogallica (vs. 29 or 30 for P. pathirana). Pempheris pathirana is also a close relative of P. kruppi, found on the coast of Yemen and Socotra. Pempheris kruppi differs in the steeper angle of the jaws, 37–41 anal-in soft rays (vs. 38–43 in P. pathirana), and in dentition. Specimens of P. pathirana have a single row of recurved teeth anteriorly in the upper jaw, compared to two in most other species in the rhomboidea species complex, followed in P. pathirana by many irregular rows of very small teeth. Two related species are found in India: P. sarayu and P. mangula. Pempheris sarayu differs in having a shorter pelvic in, 6.15 in SL, and a mode of 19 pectoral-in rays. Pempheris mangula has a characteristic dark brown or dark red margin on the anal in. The representative of the schwenkii complex in India is P. bineeshi, and in Sri Lanka the local representative is P. trinco. The unrelated P. malabarica is also found in the region. No DNA sequences are available for P. pathirana. Pempheris peza Randall & Victor, n. sp. Figure 30, Tables 1–3. Holotype.

Color in alcohol as in Fig. 30; scales brown with whitish edges; dorsal in with a broad anterior black margin expanding slightly to a distal spot; caudal in with broad blackish border posteriorly and on dorsal and ventral margins; anal in with a broad, very dark brown band at base, the outer part of in pale yellowish and nearly as broad; three blackish spots at margin of in (one to three such spots on a few paratypes); these are not remnants of a black border, nor are they parasites (though they could be of parasitic origin); iris light yellow, the upper half of the yellow dorsal part of the iris abruptly black (irregular on holotype, but a straight margin on most paratypes). Color in life unknown. Etymology. This species is named Pempheris peza from the Greek meaning border, in reference to the very broad blackish border on all of the outer edge of the caudal in. Remarks. The 16 specimens of the new species are all from a single collecting station at Ponta do Ouro, a small coastal town 10 km north of the border of South Africa and Mozambique. Two of the collectors were asked for details of the collection. They only recall that rotenone was used in relatively shallow water. Two other species of the schwenkii complex occur along the southern Mozambique coast, P. ibo and P. connelli: P. ibo has many fewer lateral-line scales (43–49), and P. connelli has a wider body and less marked caudal in. No DNA sequences are available for P. peza. Pempheris rochai Randall & Victor, n. sp. Figure 31, Tables 1–3. BIN AAC6084 (in part). Holotype.

Dorsal-in rays VI,10; anal-in rays III,39; pectoral-in rays 17 or 18; lateral-line scales 59; lateral line moderately arched anteriorly, rising 1/2 orbit diameter above level of origin of lateral line; outer layer of scales almost totally missing (no cycloid vs. ctenoid scale characters possible); gill rakers 28; body moderately deep, depth 2.25 in SL, and compressed, the width 3.1 in depth; head length 3.15 in SL; eye moderately large, orbit diameter 6.8 in SL; interorbital width 11.6 in SL; jaws moderately oblique, the edge of maxilla forming an angle of about 68° to horizontal axis of body; knob at tip of lower jaw bulges more posteriorly than anteriorly; upper jaw with a single row of sharply conical, recurved teeth that are progressively smaller posteriorly to side of jaw, ending as small nodules; lower jaw with a narrow band of very small conical teeth in three to ive rows medially, progressively more recurved inwardly; predorsal length 2.65 in SL; longest dorsal-in rays broken; pectoral-in length 3.0 in SL; prepelvic length 2.5 in SL; pelvic ins just reaching anus, 6.15 in SL. Color in alcohol as shown in Fig. 31; the scales silvery with thin brown margin (when wet, they show lavender iridescence; however these are the scales of the inner layer); leading edge of dorsal in dark brown, broadening to a dark spot distally; dark brown band at base of anal in broad; tips of heavily abraded anal rays with traces of black pigment, suggesting a blackish margin when intact; caudal in probably fully bordered in dark brown or black in life; pectoral ins with 45 Figure 31. Pempheris rochai, holotype, CAS 236522, female, 116.5 mm, Ras Hamar, Oman (H.A. Randall). Spear wound below pectoral in. a narrow blackish band at base of rays, except lateral two or three rays. Color in life unknown. Etymology. This species is named for the collector, Dr. Luiz A. Rocha, Curator of Ichthyology at the California Academy of Sciences, in recognition of his broad body of ichthyological research on the phylogenetics of reef ishes. Remarks. Species of Pempheris typically have 9 dorsal soft rays, but one can expect an occasional rare individual of any species of the genus to have 10. The holotype of P. rochai, with 10 dorsal soft rays, may be such an individual, or 10 may be the true count for the species. More specimens will provide the answer. It is distinctive for its single row of enlarged curved teeth medially in the upper jaw (vs. two or three in other species), relatively large eye, and the unusually broad dark brown band at the base of the anal in. The barcode mtDNA COI sequence of the holotype of P. rochai is the same as P. connelli from South Africa and P. hollemani from Madagascar, indicating either a recent split of closely related species or some degree of gene low across the western Indian Ocean between the three species (Fig. 1).

Color of holotype when fresh in Fig. 32. Etymology. This species is named Pempheris rubricauda from the Latin for red-tailed, in reference to the bright red-orange coloration of the broad central part of the caudal in. Remarks. The new species is presently known only from NW Madagascar. The barcode mtDNA COI sequences of P. rubricauda (along with a sequence from P. ternay from Seychelles) form a barcode lineage very close, only 0.66% divergent, to the lineage comprising P. tominagai from the Red Sea and P. xanthomma from Yemen. That set of four species is sister to two other clades of schwenkii-complex lineages that occupy nonoverlapping ranges in the Indo-Paciic: 3.4% divergent from the lineage that comprises P. hadra from Maldives, P. bineeshi from India, and probably true P. schwenkii from Indonesia (Fig. 1), as well as 3.6% divergent from a lineage of P. aff. schwenkii from the Paciic Ocean.

This species is known from a single collection at Obhur Creek, 36 km north of Jeddah, Saudi Arabia; the topography is a broad tidal channel with steep marginal reefs. S. Bogorodsky observed feeding on zooplankton by this species and P. lavicycla near the surface from the light of a nearby boat landing. Pempheris sergey is one of seven species of the schwenkii complex from the Red Sea; it is distinguished by color in life, having two rows of teeth medially in the upper jaw, and a slender body, i.e. the body depth more than 2.5 in SL. The color is similar to the closely related P. viridis: morphological differences include three rows of teeth medially in the upper jaw and a straight dorsal proile in the latter. Both P. sergey and P. viridis have relatively narrow dark bands at the base of the anal in, vs. P. xanthomma and some others. Pempheris tominagai differs by having three rows of teeth in the medial upper jaw, a wider body, and at most dusky edges to the caudal in. Mitochondrial DNA sequences from the type specimen (obtained during review) match those of P. tominagai; more specimens are needed to resolve the genetic relationships in this group. 48 Pempheris shimoni Randall & Victor, n. sp.

This species is named for the type locality, the small town of Shimoni, a port near the border of Kenya and Tanzania. The speciic epithet is a noun in apposition. Remarks. Measurements in the above description are from our only adult specimen (the paratypes are all juveniles). We regret not having more information on the ish collection made at Shimoni by the Smiths 63 years ago. No DNA sequences are available for P. shimoni. Figure 34.

Color in alcohol as in Fig. 35. Color in life unknown. Etymology. This species is named for Shirleen Smith of the Division of Fishes, United States National Museum of Natural History, in appreciation of the many loans of Pempheris and other ishes that she has prepared for the senior author. The speciic epithet is a noun in apposition. Remarks. This species is known from a single collection at Hurghada in Egypt. Pempheris shirleen is one of seven species of the schwenkii complex from the Red Sea; it is distinguished by very short pelvic ins, having three rows of teeth medially in the upper jaw, cycloid scales on the nape and most of chest, a thinner body (body width more than 2.7 in body depth), and a moderately deep body (body depth less than 2.4 in SL). No DNA sequences are available for P. shirleen. Figure 35. Pempheris shirleen, holotype,USNM 402228, female, 105 mm SL, Hurghada, Egypt, Red Sea (H.A.

Dorsal-in rays VI,9; anal-in rays III,41 (40); pectoral-in rays 17 (17 or 18); lateral-line scales 59 (56); gill rakers 30 (31); body depth 2.35 (2.3) in SL; body width 2.6 (2.8) in body depth; head length 3.25 (3.3) in SL; eye diameter 7.0 (7.4) in SL; interorbital width 11.7 (11.8) in SL; mouth oblique, forming an angle of 61– 66° to horizontal axis of body; upper-jaw dentition typical of the genus, with two irregular rows of recurved teeth on each side of symphyseal gap, one protruding forward, the other strongly recurved, reduced to a single row of gradually smaller teeth nearly half way back in jaw; tip of lower jaw expanded to a distinct knob, extending both anteriorly and posteriorly, and strongly protruding when jaws fully closed; lips with well-developed bristle-like papillae; lower-jaw teeth to either side large for the genus, beginning medially with seven rows, those of outer row erect or slightly recurved, the remaining inner teeth progressively longer and more recurved, teeth smaller and in fewer rows posteriorly in jaw; tongue triangular, straight-sided, with irm pointed tip; scales on nape, below dorsal in, and on chest ctenoid; scales on side of caudal peduncle cycloid; predorsal length 2.7 in SL; prepelvic length 2.45–2.5 in SL; dorsal, caudal, and pectoral ins damaged; pelvic ins reaching anus, 6.35 in SL. Color of holotype in alcohol as in Fig. 36; large spot at pectoral-in base probably dark brown in life. Color in life unknown. Etymology. This species is named in honor of James Leonard Brierly Smith and Margaret Mary Smith, not only for being the collectors of the holotype, but also for the major contributions they have made in pioneering ichthyology in South Africa, describing hundreds of species, and writing numerous publications on the ishes of southern Africa. Remarks. Two specimens of Pempheris were collected at Chumbe Island in 1952 by the Smiths, each the holotype of a new ish, i.e. the present species and P. leiolepis, the former with ctenoid scales on the chest and the latter with cycloid scales and three rows of upper-jaw teeth. The paratype of P. smithorum was collected by the irst author and associates from nearby Maia Island with no suspicion at the time that it might be an undescribed species. No photographs and no color notes were taken. It is more copper-colored than the holotype. No DNA sequences are available for P. smithorum. Figure 36.

Dorsal-in rays VI,9; anal-in rays III,39 (38 or 39); pectoral-in rays 17 (17 or 18); lateral-line scales 50 (52–55); scales on nape, below dorsal in, and side of caudal peduncle cycloid, scales on side of chest cycloid except for a few ctenoid scales ventroanteriorly; gill rakers 31 (30–33); body depth 2.5 (2.3–2.6) in SL; body width 2.45 (2.55–2.7) in body depth; head length 3.3 (3.2–3.3) in SL; dorsal proile of head slightly convex; eye very small, orbit diameter 7.9 (8.1–8.65) in SL; interorbital width 11.5 (11.3–11.8) in SL; mouth oblique, forming an angle of 63°(62–63°) to horizontal axis of body; tip of lower jaw projecting anterior to upper jaw when mouth fully closed; teeth conical and recurved, those medially in upper jaw in three irregular rows, soon reduced to two rows, and inally to a single row of very small teeth near end of jaw; teeth in lower jaw similar but much smaller, more slender, in three to four irregular rows medially, then progressively fewer and smaller toward end of jaw; lips yellowish brown, densely stippled with small purple papillae; tongue triangular, straight-sided, with pointed tip; predorsal length 2.75 (2.7–2.75) in SL; prepelvic length 2.5 (2.5–2.6) in SL; longest dorsal-in ray 3.8 (4.0–4.1) in SL; all caudal-in rays broken; pectoral-in length 3.05 (3.15–3.3) in SL; pelvic ins reaching or extending slightly posterior to anus, their length 6.3 (6.8–6.85) in SL. Color in alcohol as in Fig. 37. Color in life unknown. Etymology. This species is named for the acronym of Tel-Aviv University, in appreciation of their large loan of Red Sea specimens of the genus Pempheris, including the largest specimen of the present species. The speciic epithet is a noun in apposition. Remarks. The most distinctive morphological character of this species is the small eye, smaller than for the other six members of the schwenkii complex in the Red Sea. Only P. micromma from Oman has a smaller eye; note that the preserved holotype of P. micromma in Fig. 25 has a different body shape and has different tooth row patterns. Pempheris zajonzi from Yemen shares the small eye and three tooth rows in the upper jaw, but has a larger head and fewer gill rakers. No DNA sequences are available for P. tau. Figure 37.

Dorsal-in rays VI,9; anal-in rays III,36; pectoral-in rays 17; lateral-line scales 51; gill rakers 28; body depth 2.45 in SL; body width 2.85 in body depth; head length 3.25 in SL; eye relatively small and precisely circular, the orbit diameter 7.45 in SL; lips smooth; interorbital width 11.3 in SL; mouth oblique, forming an angle of 60° to horizontal axis of body; tip of lower jaw slightly anterior to upper jaw when mouth fully closed; teeth small, pointed, and recurved, those in upper jaw in two rows medially, the teeth of the upper row projecting forward, those of the lower row curving downward; teeth progressively smaller and narrowing to a single row about half way back in jaw; teeth in lower jaw very small and densely spaced, in a band of three or four rows medially, progressively more retrorse inwardly, those of inner row largest and nearly horizontal; outer layer of scales totally missing, and many of inner layer as well; predorsal length 2.65 in SL; longest dorsal-in ray (from photograph) 2.7 in SL; pectoral-in length 3.0 in SL; prepelvic length 2.5 in SL; pelvic ins just reaching origin of anal in, 6.0 in SL. Scaleless color silvery gray with a vertical brown line on each scale pocket; color when fresh as shown in Fig. 38. Etymology. This species is named for the type location, Ternay Marine National Park on the island of Mahé, where one can no longer collect ishes, but where one can enjoy viewing and photographing them at close range. The speciic epithet is a noun in apposition. Remarks. This species shares the black-bordered red caudal in with P. rubricauda from Madagascar; it is separated by length of the pectoral ins, the number of lateral-line scales, and the angle of the maxilla. Pempheris ternay is the second schwenkii-complex species identiied from Seychelles; P. argyrea shares most meristics with P. ternay, but does not have the prominent red tail. The barcode mtDNA COI sequence of P. ternay is almost the same as for P. rubricauda, and the two form a lineage diverging by only 0.66% from the lineage including both P. tominagai from the Red Sea and P. xanthomma from Yemen (Fig. 1). That set of four species diverges by 3.4% from the lineage comprising P. hadra from Maldives, P. bineeshi from India, and probable true P. schwenkii from Bali, Indonesia. Figure 38.

Dorsal-in rays VI,9; anal-in rays III,40 (36–41); pectoral-in rays 17 (17); lateral-line scales 50 (49–52); gill rakers 30 (29–30); body depth 2.45 (2.4–2.55) in SL; body width 2.5 (2.55–2.65) in body depth; head length 3.0 (2.9–3.2) in SL; dorsal proile of head slightly convex; eye small, orbit diameter 7.7 (7.6–7.65) in SL; interorbital width 11.1 (11.4–11.8) in SL; mouth oblique, forming an angle of 64° (65–67°) to horizontal axis of body; tip of lower jaw projecting anterior to upper jaw when mouth fully closed (very slightly on smallest paratype); teeth conical and recurved, those at front of upper jaw in two irregular rows, reduced opposite nostrils to a single irregular row of progressively smaller teeth ending as a row of tiny nodular teeth in lower jaw very small, in three to four irregular rows medially, progressively fewer and smaller toward end of jaw; lips brown with numerous, very small, dark brown papillae; tongue a straight-sided triangle with pointed tip; many outer-layer scales missing from nape, below dorsal in, and on chest of all type specimens, but enough to conclude that these areas have cycloid scales, except for a few ctenoid scales ventrally on chest near opercle; predorsal length 2.75 (2.75–2.8) in SL; prepelvic length 2.7 (2.7–2.8) in SL; longest dorsal-in ray 3.85 (broken on paratypes) in SL; all caudal-in rays damaged; pectoral-ins broken on all but 88-mm paratype, its length 3.6 in SL; pelvic ins just reaching anus, their length 6.2 (6.45–6.8) in SL. Color of holotype in alcohol as in Fig. 39; color in life unknown. Etymology. This species is named for Dr. Tilman J. Alpermann of the Senckenberg Research Institute and Natural History Museum Frankfurt in recognition of his studies on Red Sea ishes and his assistance with loans and collection data from the Museum. The speciic epithet is a noun in apposition. Remarks. The three known specimens of this species came on loan with the original label only as follows: “Pempheris vanicolensis, Roten Meer, Aqaba, 1980”. They represent one of the seven schwenkii complex species in the Red Sea, due to their small adult size (the smallest paratype is a fully mature female), slender body, and dark band at the base of the anal in. They are distinguished from other members of the complex in the Red Sea by having two rows of teeth medially in the upper jaw, a short prepelvic length, and the dark line on the pectoralin base at the insertion of the rays (vs. a band lower on the base). No DNA sequences are available for P. tilman. Figure 39. Pempheris tilman, holotype, SMF 35779, male, 96.5 mm SL, Aqaba, Jordan, Red Sea (H.A. Randall). 54 Pempheris tiran Randall & Victor, n. sp.

Collection location on wreck of ferry for type specimens of Pempheris tiran, Strait of Tiran, Saudi Arabia, Red Sea (J. DiBattista). (width nearly equal to pupil diameter) and narrow black dorsal and ventral margins; anal in dark brown at base, this color merging with dark brown of body, a middle zone of light yellowish gray, and an outer black border more than half in width anteriorly, progressively narrower posteriorly; paired ins light yellowish gray; iris bluish black, greenish gray lens nearly encircled by two pale yellowish arcs. Color in life brownish gray with red-tinged in membranes, iris with a golden ring around pupil, anal in translucent and colorless below black band along in margin. Etymology. This species is named for the type location, the Strait of Tiran between the tip of Sinai and Saudi Arabia. The speciic epithet is a noun in apposition. Remarks. The two type specimens were irst identiied as P. vanicolensis (a Paciic species) because of the prominent black border on the anal in and the in-ray and lateral-line scale counts (P. vanicolensis can be quickly distinguished by lacking the prominent dark spot around the base of the pectoral in). However, when the dentition was examined, the new species showed a distinctive tooth pattern shared only with P. malabarica in the region: an external patch of teeth on the lower jaw that is apparent when the jaws are closed. Pempheris tiran can be clearly distinguished from P. malabarica by non-overlapping gill-raker counts and very different colors and marking patterns. Both the markings and meristics of P. tiran are similar to those of P. bexillon, from the southwest Indian Ocean (see Mooi & Randall 2014), in particular the black margin along the anal in; the main difference is the distinctive external patch of teeth on the lower lip of P. tiran. In addition, P. bexillon has a predominantly yellow coloration on the ins, not apparent on the fresh photograph of the holotype of P. tiran. Pempheris lavicycla is found in the Red Sea and also shares the dark margin of the anal in, but has a bright yellow iris, a lower range of lateral-line scale counts, and no external patch of teeth. No DNA sequences are available for P. tiran. 56 Pempheris trinco Randall & Victor, n. sp. Figure 42, Tables 1–3. Pempheris schwenkii [non Bleeker] Randall & Bineesh 2014: 36. Holotype.

Fig. 42 of the holotype shows the fresh coloration with the scales intact; note the scale centers are silvery gray, and the scale edges copper-colored. A dark band along the base of the pectoral in when fresh. Holotype in alcohol orangish brown (the brown from very ine dark brown stippling), the scale edges silvery gray. Etymology. This species is named for the type location, Trincomalee, which is both a district and a major port city on the east coast of Sri Lanka. It is generally called Trinco by Sri Lankans. The speciic epithet is a noun in apposition. Remarks. Pempheris trinco is a relatively small species of the schwenkii complex; our largest specimen measures only 107 mm SL. The species is usually encountered on reefs or rocky substrata in small aggregations. Presently known only from Sri Lanka, but the range may extend more widely in the appropriate habitat. The schwenkii-complex species in neighboring south India is P. bineeshi, which differs by having a shorter predorsal and prepelvic distance, a narrower body, and a lower range of lateral-line scales. Other Pempheris species found in Sri Lanka comprise P. pathirana of the rhomboidea complex, the unrelated P. malabarica (see Appendix Fig. 2), and P. mangula might be expected on the island as well.

Color in alcohol: side of body light orangish brown, the margin of scales darker; head and back grayish brown, the head darker; dark brown band at base of anal in. Color when fresh as in Fig. 43. Etymology. This species is named for its principal color, i.e. Latin viridis for green. Remarks. Pempheris viridis is one of seven species in the schwenkii complex in the Red Sea. The unique specimen was irst identiied by the senior author as P. tominagai, but differs from the underwater photograph of the holotype of P. tominagai (Fig. 44) by its more slender body (the holotype described in Koeda et al. 2014 has body depth 2.35 in SL), a straight dorsal proile (vs. convex in P. tominagai), a highly arched anterior lateral line (in P. tominagai of equal length, the vertical rise is two-ifths orbit diameter, 17.6 in SL), and in color. Pempheris viridis is bright metallic green, has a bright yellow eye, and has a very dark band at the rear margin of the caudal in. Pempheris sergey is similar in color to P. viridis but differs by having two rows of teeth medially in the upper jaw and a convex dorsal proile. Mitochondrial DNA sequences from the type specimens of P. viridis and P. sergey (obtained during review) match those of P. tominagai; more specimens are needed to resolve the genetic relationships in this group.

Etymology. This species is named for Keith D.P. Wilson, an expert on the dragonlies of China, who collected ishes in Oman for our studies on Pempheris and took the photographs of Figs. 46 and 48. Remarks. K.D.P. Wilson and Brian W. Darvell went to Oman at the request of the irst author to collect and photograph species of Pempheris. Because they were passengers on a commercial dive boat, they had little opportunity to collect ish specimens, succeeding only in three of P. darvelli described in Randall & Victor (2014). We were fortunate to ind a specimen of P. wilsoni in a loan from the California Academy of Sciences for the holotype. It was collected at Fahal Island in the Gulf of Oman, about 4 km from the dive sites of Wilson and Darvell. The label indicates ive collectors. All divers were spearing various species of ishes, so no attempt was made to link each specimen to a collector. The underwater photographs of Figs. 46–48 were identiied as P. wilsoni by eye size, the 60° angle of the maxilla, predorsal and prepelvic lengths, lengths of the longest rays of the dorsal in as well as the paired ins, and the dark markings on the ins. Figs. 47 and 48 were irst believed to represent different species, but counts and measurements from the photographs fail to show any differences, and the group in Fig. 47 has individuals of intermediate color.

The barcode mtDNA COI sequence of the holotype of P. wilsoni is the same as several other species of the rhomboidea complex, mostly species from other locations in the region, i.e. P. rhomboidea from the Red Sea and Mediterranean, P. russellii from Pakistan, P. eatoni from southern Africa, but also P. kuriamuria which is described from the southern coast of Oman (vs. P. wilsoni from the northern coast in the Gulf of Oman)(Fig. 1).

This species is named Pempheris xanthomma from the Greek for yellow-eyed, in reference to the dominant color of the iris in both live individuals and preserved specimens. Remarks. This species was irst identiied by us as P. tominagai. Pempheris xanthomma is distinguished from the seven schwenkii-complex species in the neighboring Red Sea by having a particularly wide dark band at the base of the anal in and two rows of teeth medially in the upper jaw. The new species is separated from P. zajonzi, the neighboring schwenkii-complex species from offshore Socotra Archipelago of Yemen, by having the normal two rows of teeth medially in the upper jaw (vs. three). The barcode mtDNA COI sequence of P. xanthomma is almost the same as the sequences for P. tominagai (only 0.16% divergent) and close to P. ternay from the Seychelles and P. rubricauda from Madagascar. The group of four species diverge by 3.4% from the lineage comprising P. hadra from Maldives, P. bineeshi from India, and probably true P. schwenkii from Bali, Indonesia (Fig. 1).

Color in alcohol uniform brown except for paler scale edges (Fig. 51); leading edge of dorsal in black, expanding slightly distally; caudal in yellow with a very broad black posterior margin and narrow black upper and lower margins; black band at base of anal in very broad, about equal in width to the outer ray part of in; base of pectoral in only slightly darker than adjacent body; iris very dark bluish gray. Color in life unknown. Etymology. This species is named for the collector, Uwe Zajonz, of the Senckenberg Museum, Frankfurt, who plans to collect more specimens and obtain photographs of the new species. Remarks. Pempheris zajonzi was irst identiied by us as P. tominagai, but that species differs in having fewer lateral-line scales, and predorsal and prepelvic lengths of about 2.45 in SL. The new species is also separated from P. xanthomma, the neighboring schwenkii-complex species from the mainland coast of Yemen, by having three rows of teeth medially in the upper jaw (vs. two in P. xanthomma). Uwe Zajonz plans to make a special effort to collect more specimens and take photographs when travel to Socotra Archipelago becomes possible. No DNA sequences are available for P. zajonzi.

Williams et al. Appendix Pempheris malabarica x Pempheris russellii Appendix Figure 1; Appendix Table 1 A project of the Food and Agriculture Organization of the United Nations to document the ishery resources of the Sind Coast of Pakistan provided us with the opportunity to request specimens of Pempheris from the region. Dr. Peter Psomadakis of FAO and Hamid Badar Osmany of the Marine Fisheries Department in Karachi sent specimens, tissue samples, and photographs of P. malabarica C. & V. and P. russellii Day from the sea off Karachi. While making routine counts of in rays and scales of the specimens, one that looked like P. malabarica (BPBM 41183, male, 125 mm SL) was noted to have the unusual low number of 59 lateral-line scales (60 on the other side)(Appendix Fig. 1). Pempheris malabarica has the highest lateral-line scale count (65–75) for the genus. Other meristic data of the specimen are within the range for P. malabarica. The eye size is precisely the same as that of P. malabarica for the standard length, and the upper-jaw angle of 65° is the same; also it has a dark anterior margin on the dorsal in like P. malabarica, instead of a large distal black spot found on most species of Pempheris, including P. russellii. However, it has a deeper body like that of P. russellii and is intermediate to the two species in its pectoral-in length (Appendix Table 1). Appendix Fig. 2 of a specimen of P. malabarica and Appendix Fig. 3 of a specimen of P. russellii are provided for comparison. Suspecting the specimen to be a hybrid, the dentition was carefully compared. P. malabarica has the most distinctive dentition of the genus: the teeth in the usual two rows anteriorly in the upper jaw are nearly three times larger than those of P. russellii and project horizontally forward instead of obliquely downward. The teeth anteriorly in the lower jaw are in a pair of patches shaped like a comma, separated by a narrow medial gap. The patches are half exposed when the jaws are fully closed. The teeth are progressively larger anteriorly (the reverse is typical of the genus), the ive or six teeth at the front are stoutly conical, twice as large as remaining teeth, Appendix Figure 1.

The remaining teeth in the patches are well separated, progressively smaller, more slender, and recurved. There are two rows of small, slender, recurved teeth to the side of the jaw, narrowing to a single row posteriorly. The dentition of P. russellii is typical of the genus Pempheris, in general; that of the hybrid is intermediate. The underwater photograph of Appendix Fig. 4 shows a mixed aggregation of P. malabarica (orangish and no dorsal-in spot) and P. russellii (grayish brown with black-tipped dorsal in) on a reef off Karachi, Pakistan. In view of the proximity of the two species, it is not dificult to predict that the ova of one might at times be fertilized by the sperm of the other. Appendix Figure 4. Mixed aggregation of Pempheris malabarica and P. russellii, Karachi Reef, Pakistan (M. Farooq). 71 Appendix Figure 5. Pempheris sp. USNM 343770, 98.5 mm SL, St. Brandon’s Shoals (H.A. Randall). St. Brandon’s Shoals Fish Collections. Large ish collections were made, mainly with rotenone, in the St. Brandon’s Shoals (Cargados Carajos) of the Indian Ocean, from a sailing vessel in April 1976. The expedition was sponsored by Lewis H. Strauss and included the ichthyologists Victor G. Springer, Thomas H. Fraser, and C. Lavett Smith. Among the many species of ishes collected are what seemed to be a single small species of Pempheris of the schwenkii complex from three stations: USNM 343769, 35: 70–107 mm, SE side of Grande Passe (16°28’ S, 59°40’ E) at 0–20 feet on April 5, 1976; USNM 343770, 44: 44–114.5 mm SL, 0.5 miles S of Île Raphael (16°27’ S, 59°36’ E) at a depth of 0–30 feet, April 12, 1976; and USNM 343768, 8: 101.5–110.5 mm SL, off NW shore of Albatross Island (16°15’ S, 59°15’ E), at 0–18 m, April 14, 1976. Appendix Fig.5 illustrates a 98.5-mm specimen from the second collection. Routine measurement and meristic data were taken of the three St. Brandon’s collections in the expectation that all would be essentially the same. They are for body and in proportions and within one count for anal-in rays (38–43) and lateral-line scales (49–60). However, a surprise came with gill-raker counts. The ish of the irst collection have 27–29 gill rakers, while the next two collections have 28–30. We then searched for other characters that might show differences. The angle of the maxilla averaged about 65° for all the specimens. Whether scales on the side of the chest are cycloid or ctenoid is a valuable character for species of Pempheris. Unfortunately there are usually at least some scales missing. When the chest scales are fully present or nearly so, the ish of the irst collection have all or nearly all cycloid scales, while those of the second and third collections are mainly or all ctenoid. Unexpectedly, we found ish of all three St. Brandon’s collections that clearly had too many of the wrong kind of chest scales, suggesting hybridization. To determine the status of the species of Pempheris of these three collections is beyond our present capability, in view of the time frame to complete the manuscript. A future expedition to St. Brandon’s Shoals, with observations on habitat, underwater photographs, and taking tissue samples for genetic analysis, should be able to resolve this interesting complex of species. Unidentiied species of Pempheris. Many species of Pempheris are dificult to positively identify from underwater photographs. However, there are a few photographs that are suficiently distinct to suggest undescribed species. Appendix Figs. 6 and 7, the former from Madagascar, the latter from Sri Lanka, are examples of new species for which specimens are needed. We also believe Appendix Figs. 8 through 15, taken by Dawn Goebbels in the Watamu Marine National Park in Kenya, represent undescribed species of Pempheris. 72 Appendix Figure 6. Pempheris sp., 60 km north of Tuléar, Madagascar (G.R. Allen). Koeda et al. (2014: ig. 7a) mistakenly identiied this photograph as P. tominagai. Appendix Figure 7.
