পৃষ্ঠীয় কাঁটা (মোট ) : 1; পায়ূ কাঁটা : 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; eye at most 23% of head length and 46% of snout length; post-orbital length at least 60% of snout length; maxillary barbels unbranched, longer than head, without tubercles and bordered by a distinct basal membrane; outer mandibular barbels with many thick and short ramifications; branches of inner mandibular barbels subdivided and tuberculate; mandibular teeth moderately developed, numbering 37-43 (37 in the holotype); denticulations of pectoral-fin spines weaker on outer than on inner margin; dorsal-fin spine smooth anteriorly; humeral process triangular and keeled ventrally; adipose fin well developed and close to rayed dorsal fin; branched dorsal-fin rays, as well as dorsal- and pectoral-fin spines prolonged into filaments; spots present on body and fins (Ref. 57223).
Coloration: body more or less dark brownish, covered, as the head and adipose fin, with large, rounded, black spots; other fins with smaller black spots; membranes of maxillary barbels black (Ref. 57223).
Maximum TL was recorded at 23.8 cm (Ref. 57223). Oviparous (Ref. 205).
