Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 6 - 7; Anale zachte stralen: 4; Wervels: 35 - 36. Belongs to the Oreoglanis delacouri species group as it lacks a distinct median notch on the posterior margin of the lower lip. Can be distinguished from other members of the genus by the following combination of characters: maxillary barbel with rounded tip, dentary tooth patches separated by approximately one-quarter their width, tip of pectoral fin reaching pelvic-fin origin, body depth at anus 10.9-13.0 % SL, and adipose fin confluent with upper procurrent caudal-fin rays, caudal peduncle length 20.3-24.4 % SL, caudal peduncle depth 5.4-6.3 % SL, caudal peduncle depth 3.31-4.23 times in its length and an emarginate caudal fin (Ref. 83406).
Occurs in a rocky, fast-flowing stream (Ref. 83406).
