Diagnosis

A species of Clupisoma in which the pectoral spine does not reach past the base of the pelvic fin, the abdomen is keeled only from a vertical through the pelvic-fin origin to the anus, pectoral fin with a spine and 11 segmented rays, anal fin with 4 or 5 unbranched, and 43-50 branched rays, and first gill arch with fewer than 18 rakers on the outer face. The body is silvery or white below the lateral line posterior of the pectoral fin, and steel gray above; more anteriorly, the grayish region extends to level of the pectoral-fin origin. D. II, 7; A. iv-v, 43-50; Pt. I, 11; Pv. i, 5. Four pairs of barbels: one pair of nasal barbels, one pair of maxillary barbels; two pair of mental barbels, and one pair of outer mental barbels.

Ease of Identification easy to distinguish from other species.
