型态特徵 | 形态测量图
Diagnosis: Disc diamond-shaped (rhomboid). Snout elongated, preorbital distance 35.7-37.7% in DW. Lower lip outline with a dark, well-defined band. Shoulder region to base of tail with a row of small tubercles along the midline of disc, tubercles somewhat randomly distributed. Posterior margin of the pectoral fins uniformly rounded; of the triangular-shaped pelvic fins, almost straight or slightly sinuous, with its tips exceeding posterior margin of disc. Dorsal caudal keel absent in the holotype, vestigial in the 2 paratypes (Ref. 56441).
