A new species of pinguipedid fish, Parapercis nigrodorsalis, is described from 17 specimens collected off the North Island of New Zealand and Wanganella Bank, Norfolk Ridge, Tasman Sea, in depths of 56280 m. The species has also been photographed underwater off the Poor Knights Islands Reserve and Burgess Island, Mokohinau Group, in New Zealand. It is most similar to Parapercis binivirgata (Waite, 1904) in morphology, coloration and meristic values, but is unique among the genus in having a combination of dorsal-Fin rays V, 23, anal-Fin rays I, 19, lateral-line scales 5763, vomer with 12 irregular rows of robust conical teeth, palatines with 12 rows of small teeth, angle of subopercle smooth, 10 abdominal and 22 caudal vertebrae, and coloration, including seven broad reddish-brown bands on the upper body between the spinous dorsal-Fin and the caudal peduncle, most bands bifurcated into close-set double bars with black smudge-like blotches below, and membrane of the spinous dorsal fin black. Comparison of the mitochondrial cytochrome c oxidase subunit 1 (CO 1) genetic marker utilised in DNA barcoding produced a genetic divergence of 5.38% and 7.63% between the new species and its two closest sampled congeners. The holotype of P. binivirgata is identified from two specimens previously regarded as syntypes, some revisions are made to meristic data in the original description of the latter, and a detailed description of the revised geographic range of P. binivirgata is provided. © 2014 Magnolia Press.

The platycephlid genus Ratabulus Jordan and Hubbs, 1925 is reviewed taxonomically. The genus is defined by the long, slender canines on its upper jaw, palatine and vomer, the presence of a small free spine between the two dorsal fins, the iris lappet broad and simple dorsally, the suborbital ridge with numerous spines, the suborbitals and preopercle lacking sensory tubes in the cheek region, and lateral line scales with only a single pore posteriorly. Although the genus has been regarded as comprising only a single species, Ratabulus diversidens (McCulloch, 1914), this study presents descriptions of four: R. megacephalus (Tanaka, 1917) in southern Japan to the South China Sea, R. diversidens in eastern Australia, R. fulviguttatus sp. nov. in northwestern Australia and R. ventralis sp. nov. in northeastern Australia. R. megacephalus, having been regarded as a junior synonym of R. diversidens, is easily separable from that species in having more anteroventrally slanted oblique scale rows above the lateral line (94-112 versus 80-93). R. fulviguttatus sp. nov. is similar to R. megacephalus in having small dark spots dorsally on the body, but differs from it in having a shorter snout (30.4-34.8% HL versus 31.2-35.7% HL), longer pelvic fin (20.9-25.7% SL versus 19.5-23.1% SL), and a pale brown head and body (versus dark brown). Although R. ventralis sp. nov. resembles R. diversidens in having the nasal bone with tubercles, the former is distinguished from the latter and R. megacephalus by its longer pectoral fin (15.8-18.6% SL versus 13.9-17.0% SL). R. diversidens also differs from its three congeners in having larger brownish spots on the pelvic fin. Source

Tomiyamichthys levisquama is described as a new species from the Northern Territory and Queensland, Australia from estuaries and soft bottom marine environments. It is distinctive in body and head shape, head coloration and by the absence of ctenoid scales on the body. It is compared with the related species Tomiyamichthys russus (Cantor 1849), which has ctenoid scales on the posterior part of the body. The validity of the name Tomiyamichthys over Flabelligobius is discussed, with both genera being described in the same paper, here accepting Tomiyamichthys as the appropriate name. © Copyright 2016 Magnolia Press.

Chlorophthalmus corniger is redescribed on the basis of recently collected specimens. The species is redefined as a species of Chlorophthalmus with the lower jaw terminating in a distinctly projecting horizontal plate with strong, spine-like processes directed forward from the plate's corners; body silvery grey, with numerous minute black spots and traces of broad darker crossbars; base of anterior dorsal fin spines and distal parts of dorsal fins black; adipose fin tiny with numerous black spots; caudal fin black; 3·5 scales above lateral line; three rows of cheek scales; head very large, 34·3-40·1% standard length (LS); eye large, 29·8-40·8% head length (LH); pectoral fin long, extending to beyond dorsal fin base, 21·7-26·2% LS. Chlorophthalmus bicornis is a junior synonym of C. corniger based on the examination of the type series of both species. It is confined to the northern half of the Indian Ocean, reliably recorded from Somalia and the Gulf of Aden to southern Java, Indonesia, at depths between 200 and 500m. A lectotype and three paralectotypes were designated for C. corniger. DNA barcodes for Indian species of Chlorophthalmus were generated. © 2014 The Fisheries Society of the British Isles. Source

A new species of pinguipedid fish, Parapercis pariomaculata, is described from seven specimens collected from Lombok and the southeast coast of Bali, Indonesia. The species appears locally common, having also been photographed underwater in several other locations off Bali. It is most similar to Parapercis clathrata in morphology, colouration and meristic values, but is unique among the genus in having a combination of dorsal-fin rays IV, 21, anal-fin rays I, 17, lateral-line scales 57-58, vomer with 2-4 rows of robust conical teeth, palatines edentate, angle of subopercle produced and with small spinules, 10 abdominal and 20 caudal vertebrae, some nape scales weakly ctenoid in males, pelvic fins not reaching anal-fin origin in males, and colouration, including two small black spots on the suborbital, one above the other within a triangular reddish-brown blotch, and the arrangement of black and white blotching and other markings on the caudal fin. Comparison of the mitochondrial cytochrome c oxidase subunit 1 (CO 1) genetic marker utilised in DNA barcoding produced a significant genetic divergence of about 12.8% between the new species and its closest congener. A lectotype is designated from the two syntypes of Parapercis quadrispinosa (Weber) which is determined to be a junior synonym of P. clathrata Ogilby. Copyright © 2012 · Magnolia Press. Source
