背面の脊椎 (合計) : 1; 肛門の骨: 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).
Body shape (shape guide): fusiform / normal.
Oviparous (Ref. 205). Maximum TL recorded was 800mm (Ref. 57223).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00468 - 0.02950), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
