Parapercis randalli, a new sandperch (Pisces: Pinguipedidae) from Southern Taiwan

Parapercis randalli sp. nov. is described on the basis of four specimens collected in southern Taiwan by angling at a depth of 5–150 m. It differs from its congeners in having five broad reddish brown saddles on the dorsal surface; both jaws and anterior portion of snout reddish orange; a yellow bar with red margin on cheek; a series of 8 red bars below body axis; configuration of spots on head, dorsal and caudal fins; and a combination of morphological characters: three pairs of canine teeth anteriorly in lower jaw; no palatine teeth; vomerine teeth stout, in a single curved row; lateral-line scales 53; margin of preopercle smooth; 4th dorsal spine longest; caudal fin slightly rounded on ventral half, truncate on dorsal half, with a prolonged upper lobe; appressed pelvic fin extends beyond anus. A total of 21 valid pinguipedid species are now recorded from Taiwanese waters.

The genus Homalopteroides Fowler 1905 is resurrected and distinguished from the genus Homaloptera van Hasselt 1823based on a combination of characters including a unique mouth morphology, dorsal-fin origin over pelvic fin,≤60 lateral-line scales, and≤30 predorsal scales. Species included in Homalopteroides are H. wassinkii (Bleeker 1853), H. modestus(Vinciguerra 1890), H. rupicola (Prashad & Mukerji 1929), H. smithi (Hora 1932), H. stephensoni (Hora 1932), H. weberi(Hora 1932), H. tweediei (Herre 1940), H. indochinensis (Silas 1953), H. nebulosus (Alfred 1969), H. yuwonoi (Kottelat1998), and possibly H. manipurensis (Arunkumar 1999). Homalopteroides modestus (Vinciguerra 1890) is a poorlyknown species that was originally described from the Meekalan and Meetan rivers of southern Myanmar. It occurs in theSalween, Mae Khlong, and Tenasserim basins, and can be distinguished from all other species of Homalopteroides by thecombination of caudal-fin pattern (black proximal and distal bars, median blotch), 15 pectoral-fin rays, pectoral-fin lengthgreater than head length, 5½–6½ scales above and 5–6 scales below the lateral line (to the pelvic fin), 39–44 total lateral-line pores, no axillary pelvic-fin lobe, pelvic fin not reaching anus, orbital length less than interorbital width in adult, and maxillary barbel reaching to or slightly past the anterior orbital rim.

ABSTRACT A redescription of Bryconops gracilis is provided, a species poorly known for more than a century. Bryconops gracilis differs from all congeners by having the following combination of features: eight branched pelvic-fin rays, 31-36 anal-fin rays, 15-17 predorsal scales arranged in a regular series, two rows of premaxillary teeth, and 53-60 lateral-line scales. The species was often misidentified as B. alburnoides by sharing an overall elongated body shape, caudal fin yellowish in life, and a high number of lateral-line scales. A diagnosis between B. alburnoides and B. gracilis is provided. The holotype of B. gracilis which for many years had whereabouts unknown, was recovered, examined and illustrated by CT-Scan. Additionally, more detailed information about the type locality, morphology, color pattern (including in living specimens), habitat and distribution pattern of species are provided.

A new species of Microglanis is described from the upper rio Tocantins basin, Barro Alto, Goiás State, Brazil. This species is distinguished from the others by presenting a unique color pattern, consisting of round spots in the flank between the larger dark brown blotches. Moreover, it can be distinguished by the combination of the following features: caudal fin emarginate, the upper lobe slightly larger than the lower, lateral line relatively long, reaching vertical through posterior margin of the pelvic fin, and light stripe on supra-occipital region absent or very narrow and with irregular shape.

Chelidoperca pleurospilus (Günther, 1880) (Perciformes: Serranidae) is redescribed on the basis of the lectotype (designated herein) and 69 non-type specimens from the eastern Indian and western Pacific oceans, ranging from the Andaman Sea east to New Caledonia, and northwestern Australia north to Japan. Literature records of the species from the Red Sea and Madagascar are considered applicable to Chelidoperca occipitalis Kotthaus 1973. Chelidoperca pleurospilus is characterized by the following combination of characters: pectoral-fin rays 14–16 (modally 15); pored lateral-line scales 40–43 (43); scale rows in longitudinal series 42–47 (44); scale rows between lateral line and base of 6th dorsal-fin spine 4 (3 full-sized scales plus 1 half-sized); interorbital scales reaching mid-orbit level, not extending beyond anterior margin of orbit; scales on lower jaw ventral surface restricted to angular, not extending anteriorly onto dentary; posterior tip of upper caudal-fin lobe slightly elongate with rounded or pointed contour, that of lower lobe not elongate, with rounded or truncate contour; longitudinal row of ca. 5 dark, laterally elongate blotches (more-or-less continuous in small specimens <60 mm SL) along mid-body from behind head to caudal-fin base. The species is compared with its congeners, and morphological changes with growth in the former discussed in detail.

Schistura madhavai, new species, is described from Suriyakanda, Sri Lanka. It is distinguished from all other species of Schistura in the peninsula of India and Sri Lanka by the combination of the following characters: 8–9 wide, brown postdorsal bars separated by narrow, white interspaces; width of interspaces ¼–⅓ times width of bars; black bar at caudal-fin base wider than interspaces on the body; incomplete lateral line, ending beneath dorsal-fin base; absence of an axillary pelvic lobe; adpressed pelvic fin just reaching anus; origin of the pelvic fin on a vertical through the last unbranched dorsal-fin ray. Schistura notostigma, the only other Sri Lankan species of Schistura, is redescribed. It can be distinguished from all other species of Schistura in the peninsula of India and Sri Lanka by the combination of the following characters: 6–7 wide, brown postdorsal bars; width of interspaces ½–1 times width of bars; complete, black bar at caudal-fin base narrower than width of interspaces between bars on body; emarginate caudal fin; incomplete lateral line ending beneath dorsal-fin base; adpressed pelvic fin surpassing anus; and origin of pelvic fin beneath first branched dorsal-fin ray. Schistura madhavai is separated from S. notostigma by an uncorrected pairwise distance of 3.0–3.8% for the 16S rRNA gene fragment.

Species of the anglerfish genus Chaunax Lowe, 1846 from the New Zealand region are taxonomically reviewed with six species recognized and described: Chaunax penicillatus McCulloch; C. nudiventer Ho & Shao, a new record for New Zealand; and four species new to science. Chaunax flavomaculatus sp. nov. distinguished by having its skin covered with a mix of numerous bifurcated and simple spinules, large yellow spots on dorsal surface of fresh specimens, and brownish coloured escal cirri; Chaunax mulleus sp. nov. by having a uniformly pink body with a deep red colour on ventral surfaces of the outer pectoral-fin and pelvic-fin, and lower part of caudal fin; Chaunax reticulatus sp. nov. by having cirri on the dorsal surface of head, and a pale reticulate colour pattern on a greyish background dorsally; and Chaunax russatus sp. nov. by its very wide illicial trough that is usually as wide or wider than the diameter of the pupil, and uniformly deep red body colour with creamy white to fuzzy greyish spots or patches on its dorsal surface. A key to species recognized from the study area is given.
