Can be distinguished by the following unique combination of characters: adipose-fin base not confluent with caudal fin (vs. confluent); premaxillary tooth patches appear joined (vs. separate); lower lip connected to base of maxillary barbel by skin flap, without sulcus between them (vs. not connected, with sulcus); 6 upper + 7 lower branched caudalfin rays (vs. 7+8); dorsal fin i-5 (vs. i-7); anal fin ii-3 (vs. ii-8); pelvic-fin origin to anal-fin origin distance shorter than pelvic-fin origin to mouth distance (vs. equal); pectoral fin extending beyond pelvic-fin origin (vs. not reaching); origin of pelvic fin anterior to end of dorsal-fin base (vs. opposite to or posterior to end of dorsal-fin base); anus nearer to posterior end of pelvic-fin base than anal-fin origin (vs. nearer to anal-fin origin); anal-fin origin nearer to posterior end of pelvic-fin base than to caudal-fin base (vs. nearer to caudal-fin base); short interdorsal, tip of dorsal-fin reaching origin of adipose fin when depressed (vs. not reaching); snout length 49.1-52.9% HL; predorsal length 26.1-27.8% SL; head length 25.7-28.0% SL; head width 26.8- 27.2% SL; caudal peduncle length 22.4-26.2% SL; and caudal peduncle depth 4.8-6.6% SL (Ref. 75856).
