背棘 (總數) : 2. Diagnosis: caudal peduncle relatively long, with minimal depth as large as horizontal distance between adipose and caudal fin bases, or slightly larger (never twice as large)(Ref. 81642). Pectoral spine only partially and slightly, or not at all, serrated on its anterior margin; preorbital head length less than maximum head depth (Ref. 50834, 81642).

Barbels long, e.g. external mandibular barbel minimally 1.3 times HL, reaching to beyond tip of pectoral fin spine, maxillary barbel always reaching base of pectoral fin spine or even further (Ref. 50834, 81642). Whole body with equally large dots (Ref. 81642).
