Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 3; Mjukstrålar i ryggfenan (totalt) : 7; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 5; Ryggkotor: 41 - 43. Head conical, wide, slightly flattened. Barbel long, reaching beyond posterior edge of eye, caudal peduncle low, epithelial crests on dorsal scales absent; supraorbital seismosensory canal not connected with infraorbital one (Ref. 28796); and anal fin with 5½ branched rays (Ref. 59043).

Inhabits high-gradient stretches of large rivers with fast (not turbulent) current and gravel or sand bottom. Nocturnal, found near shores at night on mud or sand bottom. Appears to spawn early and have a short spawning period. Only large juveniles were encountered in July (Ref. 59043).
