Psilorhynchus nudithoracicus Tilak & Husain 1980

Differs from other species of Psilorhynchus by the presence of large and flap-like skin folds at the lateral corner of the mouth, which reach further posteriorly than the lower jaw cushion and are covered in large 'head of cauliflower' papillae (vs. skin folds not reaching past posteriormost part of lower jaw cushion, non-papilliated or with small dome-like papillae). Can be further diagnosed from other members of P. nudithoracicus species group by the possession of the following characters: two dorsal saddles positioned at dorsal-fin origin; L+2 row present, composed of 5-10 obvious dark brown blotches; mostly 17+17 vertebrae. Can be further separated from P. melissa by its dorsal fin with irregular dark brown or black margins (vs. dorsal fin marked with a dark brown or black band along distal edge); from P. robustus by having dorsal saddles posterior to the dorsal fin poorly developed (vs. dorsal saddles posterior to the dorsal fin well-developed), and by having the anteriormost lateral blotch equal in size or smaller than more posterior blotches (vs. anteriormost lateral blotch larger than more posterior blotches), and from P. tenure by having 9-10+9 principal caudal-fin rays (vs. 9+8); caudal peduncle length 9-13% SL (vs. 14-16% SL); presence (vs. absence) of a short mandibular canal along the anguloarticular; and presence (vs. absence) of a series of indistinct horizontal rows formed by small dark brown spots on the scales above and below the lateral line scale row (Ref. 93866).Description: Dorsal-fin rays iii.9 or iii.10; anal-fin rays ii.6; pectora-finl rays iv.10, iv.11, iv.12, v.10, v.11 or v.12; pelvic-fin rays ii.7 or ii.8 (Ref. 93866).

Dorsal soft rays (total): 12 - 13; Analsoft rays: 8; Vertebrae: 34

Occurs over small pebbles in shallow running waters where the bottom is mainly sand (Ref. 4832). Also found in a slow moving stream with a sandy bed (Ref. 93866).

Psilorhynchus nudithoracicus also known as the rainbow minnow is a freshwater ray-finned fish, a torrent minnow, which is found in the drainage systems of the Ganges and the Brahmaputra in India, Nepal and Bangladesh, as well as the Meghna River and Surma River drainage basins in India and Bangladesh. the habitat of this species is shallow running streams with sandy bottoms, usually with some pebbles laying on the sand. This species reaches a length of 8.4 cm (3.3 in).
