ຄີ (ໜາມ)ແຂງຢູ່ຫຼັງປາ (ທັງໝົດ): 2; ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ): 7; ຄີກົ້ນຂອງປາ: 11 - 13. Diagnosis: body elongated and rounded; head broad and only slightly flattened above, snout rounded (slightly pointed in small specimens); mouth inferior; maxillary barbels just reaching to pectoral fin bases, mandibular ones being shorter; osseous head shield, fairly visible through the skin, coarsely rugose with a very slight median keel; occipital process moderately broad at base and truncated posteriorly (Ref. 57224). Base of supra-occipital process moderately wide (Ref. 2683). Predorsal plate rugose, crescent-shaped; premaxillary teeth villiform forming 2 plates meeting at midline; palatine teeth in 2 large subtriangular patches which are only slightly separated at midline; no gill-rakers on posterior face of the 1st and 2nd arches; total number of anterior gill-rakers on first arch 18 to 21, on second arch 18 to 20; dorsal and pectoral fins with a strong osseous, erectile spine with anterior rim granulose and posterior rim serrated; long dorsal fin spine preceded by a very short one; adipose fin well developed; caudal fin forked, upper lobe slightly elongated (Ref. 57224). Coloration: bluish grey on the upper part, lightening progressively towards belly which is white; distal rim of fins blackish (Ref. 57224).
