RESUMO

Anthias xanthomaculatus is redescribed from re-examination of the holotype. On the basis of fin shape, meristic details and presence of two closely spaced supraneural bones, it is assigned to the genus Odontanthias Bleeker. It is compared with known Odontanthias species, and shown to be a valid species of the genus and a possible senior synonym of O. grahami Randall Heemstra. Comparative data for the holotype and three non-type specimens of O. grahami are provided.

RESUMO

A checklist of the marine and estuarine fishes of New Ireland Province is presented, with special emphasis on Kavieng District, combining both previous and new records. After the recent KAVIENG 2014 expedition, a total of 1325 species in 153 families were recorded from the region. The largest families are the Gobiidae, Pomacentridae, Labridae, Serranidae, Apogonidae, Lutjanidae, Chaetodontidae, Blenniidae, Carangidae, Acanthuridae, Scaridae, Holocentridae, Syn-gnathidae, Lethrinidae and Scorpaenidae. A total of 810 fish species (61.1 % of the total marine and estuarine fish fauna) are recorded from New Ireland for the first time.The fish fauna of New Ireland includes 142 species in transitional waters and 1264 species in marine habitats, and 54 species species in freshwater habitats. Zoogeographically, 1179 species have a wide distribution range, most frequently a broad Indo-West Pacific distribution. Among the remaining species, just 12 are endemic to New Ireland.

RESUMO

Scolopsis igcarensis Mishra, Biswas, Russell, Satpathy Selvanayagam, 2013 was described from specimens collected from coastal waters of southern India and Sri Lanka. A comparison of recently collected specimens from Bangladesh, initially identified as S. igcarensis, with Scolopsis vosmeri (Bloch, 1792) showed morphological differences between the two species are minor, and that specimens of S. igcarensis in fact represent juvenile and subadult colour forms of S. vosmeri. Underwater and aquarium observations, as well as molecular data based on the COI barcode region, support this conclusion. Accordingly, S. igcarensis is regarded as a junior synonym of S. vosmeri, which is redescribed herein. Phylogenetic analysis of COI barcodes of Scolopsis specimens produced in this study, together with those available from GenBank, indicate S. vosmeri is part of a species complex which includes two additional cryptic sister species that require further taxonomic investigation.

RESUMO

Scolopsis meridiana n. sp., described from 30 specimens collected from northern Australia, is closely related to S. taenioptera, both species having a dorsal scaled area on the head extending anteriorly to between the anterior margin of the eye and anterior nostril, the upper part of the pectoral-fin base with a reddish blotch when fresh, and lacking a small antrorse spine below the eye. However, the new species is distinguished from the latter by having two bands across the snout dorsum (vs. one band in S. taenioptera), 18-20 diagonal lines on the lateral body surface below the lateral line (diagonal lines absent), the posterior nostril horizontally elongated (vertically elongated), a deep caudal-peduncle and short pre-dorsal-fin length. Scolopsis meridiana is distributed in northern Australia, whereas S. taenioptera occurs in Southeast Asia. Two geographic populations of S. taenioptera (Philippines and remaining Southeast Asian region) are recognized following morphological and genetic analyses.

RESUMO

A new species of threadfin bream, Nemipterus andamanensis n. sp. from the Andaman Islands is described and figured. N. andamanensis resembles N. marginatus (Valenciennes, 1830) in general body form and colour pattern, but differs from the latter by having four yellow stripes on the head region, upper lobe of caudal fin and filament yellow, and lower lobe of caudal fin pinkish. The mitochondrial cytochrome oxidase C subunit I (COI) gene sequence comparison with close species revealed that Nemipterus andamanensis n. sp. has distinct genetic divergence (8.5%) from Nemipterus marginatus and other species of the genus occurring in the area.

RESUMO

Trachinocephalus gauguini Polanco, Acero Betancur, 2016 was described based on eighteen specimens collected from off the Marquesas Islands, the only location where this species has been recorded until now. Through morphological and molecular examination of Trachinocephalus specimens collected from an exploratory cruise conducted in June 2014 under the Tropical Deep-Sea Benthos program along the northern coast of the New Ireland Province, Papua New Guinea, we demonstrate the presence of this species in Papua New Guinea waters. This new record suggests a wide distribution for this rarely collected species in the western Pacific Ocean.

RESUMO

Type specimens were located in the Macleay Museum for five species described by F.L. de Castelnau: Kurtus gulliveri (syntype), Pseudoambassis macleayi (lectotype and two paralectotypes), Pseudoambassis elongatus (lectotype and paralectotype), Acanthoperca gulliveri (syntype) and Engraulis nasutus (syntypes). The last-named is shown to be a senior subjective synonym of Anchovia aestuaria Ogibly 1910, and is referred to the genus Thryssa Cuvier 1829.

RESUMO

Psammoperca datnioides Richardson 1848, long considered a synonym of P. waigiensis (Cuvier in Cuvier Valenciennes 1828), is redescribed as a valid species of Psammoperca Richardson 1848. The species is likely to be endemic to Australia, where it was formerly considered to be P. waigiensis, but differs from P. waigiensis in having the following characters: more slender body (mean depth 28.9% of SL vs. mean depth 36.7% of SL in P.  waigiensis), pored lateral-line scales 49-54 (vs. 46-48 in P. waigiensis), scale rows above and below lateral line 6½ / 10½-11½ (vs 4½ / 9½-10½ in P. waigiensis), and vertical at hind margin of maxilla posterior/behind center of eye (vs. vertical at hind margin of maxilla anterior to/in front of hind margin of eye in P. waigiensis). Live specimens of Psammoperca datnioides have a uniformly dense black or brownish body, with this dark colour on body scales and pored lateral-line scales persisting even in preserved specimens. Live specimens of Psammoperca waigiensis have a brownish body, often golden in colour, and pored lateral-line scales that are yellow-edged. The COI sequence (cytochrome c oxidase subunit I, 612 bp) of P. datnioides also is distinct from P. waigiensis, and the related and poorly known Hypopterus macropterus (Günther 1859). The latter species is redescribed and diagnosed with eight indistinct dark bands on the head and body, and dorsal-fin rays VII-I, 14-15 (vs. no dark bands and dorsal-fin rays VII-I, 12-13 in Psammoperca). Nominal species in the genus Psammoperca are discussed and Cnidon chinensis Müller Troschel 1849 (type locality: Manila, Philippines) is included as a junior synonym of P. waigiensis. Psammoperca vaigiensis Boulenger 1895 is an unneeded emendation and thus an invalid name. Psammoperca macroptera Günther 1859 is retained in the monotypic genus Hypopterus Gill 1861 in the family Latidae, although the species has been overlooked in most studies on the Latidae and/or Centropomidae. A key to the Latidae is provided.

RESUMO

A new species of threadfin bream, Nemipterus sugillatus, from Taiwan and Indonesia is described and figured. Nemipterus sugillatus n. sp. resembles N. virgatus (Houttuyn) in colour pattern but differs from the latter, notably in lacking a second yellow stripe along the base of the dorsal fin, and by the absence of a red spot at the origin of the lateral line. Nemipterus sugillatus n. sp. is also distinct from N. virgatus in having only 7 anal soft rays (versus 8) and in lacking a long trailing caudal filament. Nemipterus nematophorus Bleeker is reported for the first time from Taiwan. A key to the species of Nemipterus from Taiwan is provided.

RESUMO

Saurida lessepsianus n. sp., a lizardfish (Aulopiformes: Synodontidae) from the Red Sea and Mediterranean Sea, previously misidentified as S. undosquamis (Richardson) and more recently as S. macrolepis Tanaka, is described as a new species. It is characterised by the following combination of characters: dorsal fin with 11-12 rays; pectoral fins with 13-15 rays; lateral-line scales 47-51; transverse scale rows above lateral line 4½, below lateral line 5½; pectoral fins moderately long (extending to between just before or just beyond a line from origin of pelvic fins to origin of dorsal fin); 2 rows of teeth on outer palatines; 0-2 teeth on vomer; tongue with 3-6 rows of teeth posteriorly; caudal peduncle slightly compressed (depth a little more than width); upper margin of caudal fin with row of 3-8 (usually 6 or 7) small black spots; stomach pale grey to blackish anteriorly; intestine whitish. The species is common in the Red Sea and as a result of Lessepsian migration through the Suez Canal, it is now widely distributed in the eastern Mediterranean. The taxonomic status of two other Red Sea nominal species, Saurus badimottah Rüppell [= Saurida tumbil (Bloch)] and Saurida sinaitica Dollfus in Gruvel (a nomen nudum), is clarified. A key is provided for the species of Saurida in the Red Sea.

RESUMO

A new species of sparid fish, Dentex carpenteri, is described from nine type specimens collected off Ningaloo Reef near Exmouth, Western Australia. Four valid species of Dentex are currently known in the western Pacific, Dentex abei and D. hypselosomus in the Northern Hemisphere, and D. fourmanoiri and D. spariformis in the Southern Hemisphere. These four species comprise the "Dentex hypselosomus complex". Dentex carpenteri n. sp. is most similar to D. spariformis in overall body form, but differs from D. spariformis in having the posterior margin of the upper jaw not reaching or reaching slightly beyond a vertical at the anterior margin of eye; often with the greater part from the snout to the second infraorbital yellowish; deeper suborbital (9.7-10.9% SL); and a considerably deeper body (vs. posterior margin of upper jaw reaching clearly beyond anterior margin of eye; slight yellow region on snout; suborbital depth shallow (7.6-9.6% SL); and a less deep body in D. spariformis). The mitochondrial 16S ribosomal RNA genes (16S rRNA, 545 bp) of the above five species were analyzed using the Atlantic congener, Dentex macrophthalmus as an out-group, the results clearly indicating that D. carpenteri n. sp. is a valid and distinct species. A key to the "Dentex hypselosomus complex" is provided. The distributional information available for the five species from the western Pacific, including western Australia and the nearby eastern Indian Ocean, are discussed, with the species considered to be allopatric.

RESUMO

A new species of the fish family Labridae, Suezichthys rosenblatti, is described from specimens collected at Isla San Felix, Isla Juan Fernandez and Isla San Ambrosio, off the coast of Chile. Suezichthys rosenblatti is distinct in having a combination of 11 dorsal fin soft rays and 11 anal fin soft rays. It falls in the group of species that has 1½ scale rows above the lateral line and lack a scaly sheath at the base of the dorsal and anal fins (S. aylingi Russell, S. caudovittatus Russell, S. gracilis (Steindachner & Döderlein) and S. soelae Russell). Unlike other members of this group, S. rosenblatti has haemal arches on vertebrae 10-11 (versus haemal arch only on vertebra 10). The monotypic Nelabrichthys ornatus (Carmichael) is now included in the genus Suezichthys and a revised generic description and key to species of Suezichthys is provided. The occurrence of S. rosenblatti in the south-eastern Pacific and S. ornatus in the south-western Indian Ocean and south Atlantic Ocean represent major range extensions of the genus Suezichthys.

RESUMO

A new species of threadfin bream, Nemipterus flavomandibularis, from the Western Indian Ocean is described and figured. The new species appears most closely related to N. bipunctatus (Valenciennes), but differs principally in colour pattern: N. flavomandibularis is distinct from N. bipunctatus in having two yellow bands on the snout, the upper lip narrowly edged with yellow; and lower lip and chin beneath lip yellow, this colour extending as a narrow band posteriorly to lower margin of opercle. Also, in N. flavomandibularus the scale rows below the lateral line are more or less horizontal (versus distinctly ascending anteriorly in N. bipunctatus), and the maxillary reaches to between level of posterior nostril and anterior margin of eye (versus reaching to below the anterior half of the eye in N. bipunctatus).

RESUMO

Anampses viridis Valenciennes 1840 is known from only three specimens collected from Mauritius, and despite intensive sampling, the species has not been seen or reported since it was originally described. This apparent failure to 'rediscover' A. viridis at Mauritius has led to speculation that it is extinct, and the species has been widely cited as an example of a marine fish extinction. Far from being extinct, Anampses viridis has been taxonomically confused and actually is the adult male (terminal phase) colour form and a junior synonym of A. caeruleopunctatus Rüppell 1829, a species that is common and widespread throughout the Indo-West Pacific region.
