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 in having a combination of the following characters: short nasal barbel reaching to midway between its base and anterior orbital margin, tip of maxillary barbel rounded, tip of pectoral fin reaching pelvic-fin origin, adipose fin separate from upper procurrent caudal-fin rays, caudal peduncle length 20.8-26.6 % SL, caudal peduncle depth 2.9-4.4 % SL, caudal peduncle depth 4.88-8.42 times in its length, and a lunate caudal fin with upper and lower first principal rays of approximately equal length (Ref. 83406). Description: Dorsal fin rays i,5 or i,6; anal fin rays i,3 or i,5; pectoral fin rays i,17, i,18 or i,19; pelvic fin rays i,5. Paired fins greatly enlarged, forming an elongate ovoid adhesive disc with body (Ref. 83406). |
