A New Species

Acanthocobitis pictilis, new species, is described from the Ataran drainage in Myanmar and the Mae Khlong drainage inThailand. It had earlier been misidentified as A. rubidipinnis. It is distinguished by, among other characters, its colour pat-tern, especially the dark brown triangular saddles in the upper half of the body, strongly slanted anteriorly and becomingalmost vertical posteriorly, becoming paler in the middle, and forming pairs of narrow saddles in large individuals; lateralline complete; 12 ½ or 13 ½ branched dorsal-fin rays. Acanthocobitis mandalayensis is a valid species, removed from the synonymy of A. botia.

Heteroclinus argyrospilos, n. sp. is described as a new species from specimens sampled by sled and dredge in 55–100 m off South Australia and Western Australia. The species has a strongly compressed body and spatulate orbital tentacle similar to some shallow water species, particularly those of the Heteroclinus heptaeolus complex, which is characterized by having three segmented dorsal-fin rays, with the last two rays widely separate from the first ray. It is distinct from other Australian clinids in having two segmented dorsal-fin rays, well separated from the last dorsal-fin spine and a reduced lateral line on the body. It is known from a greater depth than other members of the genus.

Depth Distributions

A new species of the uranoscopid genus Kathetostoma Günther, 1860, is described from New Zealand waters, where it is broadly sympatric with its sole local congener K. giganteum Haast, 1873. The new species is readily recognised by its broad, saddle-like dark bands that cross the body dorsally (versus bands absent or only faintly developed), rather robust and short body (vs slender and elongate), and fewer numbers of vertebrae (30–31 versus 33–34), dorsal fin rays (15–17 versus 17–19) and anal fin rays (15–16 versus 17–18). Although both species have extremely broad depth distributions, the new species appears to be restricted to less than about 500 m, with its greatest abundance at 100–300 m, while K. giganteum reaches over 1000 m, and has its greatest abundance at 200–400 m. A brief redescription of K giganteum is also provided. Kathetostoma fluviatilis Hutton, 1972, the oldest New Zealand name that applies to this genus, is regarded as a nomen dubium.

The Pseudochromis reticulatus complex is diagnosed to include species of Pseudochromis with the combination of a pointed caudal fin (rounded with middle rays produced), a reticulated colour pattern on the upper part of the body, dorsal-fin rays modally III,26, anal-fin rays modally III,15, and pectoral-fin rays modally 18. Members of the complex include P. reticulatus Gill & Woodland, P. pictus Gill & Randall, P. tonozukai Gill & Allen, P. jace Allen, Gill & Erdmann and P. stellatus new species. The last-named is herein described from six specimens from Batanta and Batu Hitam in the Raja Ampat Islands, West Papua, Indonesia. It is distinguished from other members of the complex in live coloration, and in having higher mean numbers of scales in lateral series and of anterior lateral-line scales (36–38 and 29–32, respectively), and a deeper body as measured from the dorsal-fin origin to pelvic-fin origin (31.8–33.5 % SL).

Parapercis macrophthalma is confirmed as a valid species and redescribed on the basis of the holotype and other specimens collected from the type locality, Taiwan, and Japan. It is morphologically similar to P. muronis Tanaka, 1918, but differs in having five vertical transverse bars that extend well below the lateral line versus five oblique transverse bars, with the third to fifth bars ending on or above the lateral line. A new species is also described on the basis of a specimen collected from southwestern Taiwan. It is distinct in having numerous pores interconnected by canals on the head, forming 10 vertical or oblique rows on the cheek and opercular apparatus, predorsal scales extending to the level of the posterior margin of the eye, four dorsal-fin spines, six oblique bars laterally on the body, and a combination of other characters. A key to species of Parapercis with narrow transverse bars on the upper body is provided.

A New Species

Botia udomritthiruji sp. nov. is described from the Tenasserim River drainage in southern Myanmar. It can be distinguished from congeners by its color pattern, consisting of five dark vertical bars on the body, with the central portion of these bars paler than its edges; with increasing age, the edges of these bars become more irregular and darker, and irregular dark spots on the pale interspaces begin to form, sometimes fusing with the edges of the vertical bars. In morphology, it differs from congeners by a combination of: body depth at anus 23.4–27.7% SL, caudal peduncle depth 15.9– 18.7% SL, and 12 dorsal-fin rays. Evidence for considering B. macrolineata a junior synonym of B. dario and for considering B. rostrata a species distinct from B. almorhae is also presented here.

A New Species

A new species of Characidium Reinhardt, 1867 endemic to tributaries of the upper rio Paraguaçu in the Chapada Diamantina, Bahia, Brazil, is described. The new species can be distinguished from its congeners except C. bahiense, C. bimaculatum, C. laterale, C. nana, C. nupelia, and C. xavante, by having a conspicuous peduncular blotch in addition to the basicaudal spot on the base of the middle caudal-fin rays. Among other features, the new species differs from C. bahiense, C. laterale, C. nana, C. nupelia, and C. xavante by having a complete lateral line with 32–36 perforated scales (vs. lateral line short, with 9–11 perforated scales), and from C. bimaculatum by the body pigmentation pattern, with secondary bars present (vs. absent), total bars 11–16 (vs. 10–12), peduncular blotch rounded (vs. horizontally elongated), and mature males not having a darker dorsal fin (vs. proximal third of dorsal fin darker in mature males). Characidium bimaculatum, a poorly known species from Northeastern Brazil, is redescribed.
