簡短描述

背棘 (總數) : 1; 臀棘: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at most 60% of snout length; maxillary barbels unbranched, not fringed or very slightly fringed at base, shorter than head, without tubercles or basilar membrane; mandibular barbels with a long simple and relatively thin ramifications; mandibular teeth numbering 10-16; dorsal-fin spine smooth anteriorly, pectoral-fin spines weakly denticulate; humeral process triangular and rather pointed posteriorly, its upper margin concave; adipose fin poorly developed, distinctly separated from rayed dorsal fin; colour uniform, sometimes with very fine punctuations (Ref. 57223).
Coloration: uniformly brownish, with numerous small, rounded spots on sides and adipose fin (this colour corresponds to a stuffed specimen)(Ref. 57223).
Oviparous (Ref. 205). Maximum TL recorded was 800mm (Ref. 57223).
