The Pectoral rays are16 (rarely 15 or 17). Gill rakers count to be 29 to33. The body is depth 3.25-3.8 in SL, the head length (HL) is 2.85-3.1 in SL, long snout small eye, barbels very long, the longest dorsal spine 1.5-1.7 in HL, the penultimate dorsal ray is 1.1-1.2 in length of last dorsal ray; pectoral-fin length is 1.5-1.7 in HL; pelvic-fin length is 1.35-1.55 in HL.
