背棘 (總數) : 1; 臀棘: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; snout at most 50% of head length and at most 80% of head width; post-ocular length at least 30% of head length; maxillary barbels shorter than head, bearing externally rather long and more or less tuberculate ramifications and a short, but distinct, basal membrane; outer and inner mandibular barbels with long, simple and finely tuberculate branches; mandibular teeth long, numbering 6-10; pectoral-fin spines more strongly denticulate on inner than on outer margin; dorsal-fin spine denticulate on lower half of anterior margin; humeral process triangular and deep, short and granulose, but not keeled ventrally; adipose fin very well developed and rather close (in large individuals contiguous) to rayed dorsal fin (Ref. 57223).
Coloration: ground colour greyish-brown, ventral areas lighter; caudal fin red, at least in live specimens; young individuals with fine specks scattered over dorsal body region and fins (Ref. 57223).
Body shape (shape guide): fusiform / normal.
