Taggstrålar i ryggfenan (totalt) : 1; Taggstrålar i analfenan: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels longer than head but not reaching to pelvic fins, unbranched and without tubercles or distinctly visible basilar membrane; outer mandibular barbels with thin, rather long ramifications; branches of inner mandibular barbels short, thick and globose; mandibular teeth numbering 22-26 (25 in the holotype); denticulations of pectoral-fin spines weak, but stronger on outer than on inner margin; dorsal-fin spine smooth anteriorly; dorsal- as well as pectoral-fin spines distinctly curved distally; humeral process scarcely keeled ventrally; adipose fin rather well developed, low, distinctly separated from the rayed dorsal; maxillary barbels lemon-yellow; outer margins of caudal-fin lobes black (Ref. 57223).
Coloration: back black, belly lighter, bronze-coloured; maxillary barbels citric-yellow in fresh specimens (white after preservation in formalin); all fins blackish, except the caudal which is centrally yellow and has black-edged outer margins (Ref. 57223).
Body shape (shape guide): fusiform / normal.
Oviparous (Ref. 205). Maximum TL recorded was 23.8 cm (Ref. 57223).
