Pethia poiensis, a new cyprinid species, is described from the Challou River, Chindwin Basin, Manipur, India. The new species is characterised by an incomplete lateral line with 7–9 pored scales, the absence of barbels, 19–20 scales in lateral series, 9–10 pre-dorsal scales, 18 pre-anal scales, 3½ scales between dorsal-fin origin and lateral line, three scales between lateral line and pelvic-fin origin and a unique colour pattern consisting of a humeral spot encompassing the third and fourth lateral-line scales, a caudal spot on the 16th and 17th lateral series scales and a black stripe along the flank. A revised key to the species of Pethia found in the Chindwin-Irrawaddy drainage is presented.

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).

Cabdio crassus, a new fish species, is described from the Kaladan River in Mizoram, India. The new species is distinguished from all its congeners by having a ventral keel extending from the middle of the chest, between the posterior base of the pectoral fin and along the abdomen up to the anus (vs. more or less keeled median scales from mid-point of abdomen between posterior base of pelvic fin up to anus in all other Cabdio) and 11½–12½ branched anal-fin rays (vs. 7 in C. jaya and 9 in both C. morar and C. ukhrulensis). It is further distinguished from C. morar and C. ukhrulensis by possessing more lateral-line scales (45–51 vs. 38–42 in C. morar and 35–37 in C. ukhrulensis), more predorsal scales (20–23 vs. 17–18 in C. morar and 14 in C. ukhrulensis) and more lateral transverse scales (½7/1/3½ vs. 5/1/2 in both C. morar and C. ukhrulensis). It also differs from C. jaya in having fewer lateral-line scales (45–51 vs. 52–60), more lateral transverse scales (½7/1/3½ vs. 5/1/3) and more pharyngeal tooth-rows (3 vs. 2). Furthermore, the cytochrome c oxidase sub unit I (coi) gene sequence separates Cabdio crassus from all other Cabdio species (interspecies distance ranges from 7.8–12.3%). The anomalies observed among the GenBank sequences of the genus Cabdio are discussed and resolved.

Garra findolabium, new species, is described from the Red River (Yuan-Jiang in Chinese, Song Hong in Vietnamese) in Yunnan, China. It can be distinguished from all other congeners in Southeast Asia and China by the following combination of characters: posterior edge of the oral sucking disc with a median fissure and divided it into two lamellas; caudal fin with an anomalistic dark patch, extending to 50% of length of caudal fin; no barbels; absence of proboscis in front of nostrils; 37–38 lateral-line scales; 16 circumpeduncular scales; distance of anus to anal-fin origin about 33.3–38.7% of distance of pelvic-fin origin to anal-fin origin.

Bangana brevirostris, new species, is described from the Lancang-Jiang in Yunnan, Southwest China. It can be distinguished from all other congeners by the following combination of characters: a pair of minute rostral barbels; mental groove short and shallow; dorsal fin with 12–13 branched rays; 42–44 lateral line scales; eye large, its diameter 28.1–32.9 % of head length; snout short, its length 25.5–32.7 % of head length. It shares the same postlabial groove-type with Bangana dero and B. devdevi, which makes them very different from other congeners.

ABSTRACT A new species of Boehlkea is described from rio Japurá, Amazon basin. The new species differs from B. fredcochui by the presence of a vertically elongate humeral spot (vs. absence), complete lateral line (vs. incomplete), four rows of scales below lateral line (vs. three), and lower number of branched anal-fin rays (17-21 vs. 22-25), and from B. orcesi by the higher number of maxillary teeth (13-14 vs. 5-12), greater head length (27.9-29.9% vs. 24.3-27.5% of SL), and by the color pattern (basal half of dorsal-fin, distal portion of pelvic-fin, lower caudal-fin lobe and anal-fin with black chromatophores vs. absence of black chromatophores in the fins).

A new Tyttocharax species from the Güejar River system, near the Macarena Mountains in Colombia is described. This is the first record for the genus from the Orinoco basin. The combination of the following characters distinguish Tyttocharax metae from its congeners: presence of bony hooks on the pectoral and caudal-fin rays; bony hooks on the anal-fin rays larger than those on the pelvic-fin rays; pectoral-fin rays i,5-6,i; presence of three unbranched dorsal-fin rays; absence of an adipose fin; four scales rows between the anal-fin origin and the lateral line; and four scale rows between the pelvic-fin and the lateral line. Ecological characteristics of the habitat of the new species are also presented.

A new species of Bryconops is described from the rio Maicuru, a tributary of the left margin of the lower Amazon River, Pará, Brazil. Bryconops chernoffi new species, differs from all its congeners by the presence of an elongated dark patch of pigmentation immediately after the posterodorsal margin of the opercle, running vertically from the supracleithrum to the distal margin of the cleithrum (vs. absence of a similar blotch), and by a dark dorsal fin with a narrow hyaline band at middle portion of dorsal-fin rays (vs. dorsal fin hyaline or with few scattered chromatophores). It differs further from all its congeners, except B. colanegra, by the presence of a blurred black stripe at the anal fin base. It differs from B. colanegra by possessing fewer predorsal scales (8–9 vs. 10–11) and in that the third infraorbital contacts the preopercle ventrally (vs. third infraorbital not contacting preopercle ventrally). The new species is assigned to the subgenus Creatochanes by the number of maxillary teeth, and ossification and denticulation of the gill rakers.

A new species of large-sized brackishwater threadfin, Polydactylus luparensis, is described from the Batang Lupar River in Sarawak, Malaysia, Borneo on the basis of 5 specimens (610–715 mm standard length).

Polydactylus luparensis is currently known only from the mouth of the Batang Lupar River.

A new species of Schistura is described from the Kwai Noi, Mae Khlong basin, in the Thong Pha Phum District ofKanchanaburi Province in western Thailand. The species is distinguished from all other species of Schistura by a uniformdusky brown color pattern without marks on the dorsum or side of body and with many conspicuous supplementaryneuromasts along the lateral line and on the head. It is further distinguished from other species of Schistura lacking markson the body by its dark brown color, an incomplete lateral line extending only to beneath the dorsal fin, and the origin ofthe dorsal fin located above the origin of the pelvic fin. The species is small, reaching only 46.0 mm SL, 55.1 mm TL, and inhabits shallow gravel and rubble riffles in small streams.
