背面の脊椎 (合計) : 1; 肛門の骨: 0. Diagnosis: 85-90 movable mandibular teeth, forming a long series; head width 96.6-99.4% HL; postocular length at least 60% of snout length; maxillary barbels without a basal membrane, slightly longer than head length and reaching to base of pectoral spine; dorsal spine prolonged by a short filament, without serration along anterior edge and a few serrations along posterior edge; entire margin of opercle smooth; caudal fin without single dark patch at base of each fin lobe (Ref. 81251).
Body shape (shape guide): fusiform / normal.
Oviparous (Ref. 205). Maximum total length reported as 31.4 cm (Ref. 3202, 81251) seems based on Ref. 82238 (holotype size), but is more likely 21.4 cm based on the holotype picture on the MNHN collection website, which agrees to the maximum standard length reported and observed (T. Musschoot, pers. comm.).
