The head is typically sharp and narrow; the inter-orbital distance is 1.2-1.9 times the eye diameter in males and 1.4-1.9 times in females; the skull is narrow, with the ethmoid bone longer than wide; the frontal bones are narrower relative to other reophilic barbs, notably in the anterior part; infraorbital bones are narrow, and the lachrymal bone is longer than in other reophilic barbs and possesses a long manubrium; the height of the manubrium is 10-13% the lachrymal bone length; the kinethmoid bone is more robust than the one found in other reophilic barbs (Ref. 107618). Thick lips and barbels with granular appearance; the first pair of barbels is short and positioned at the anterior extreme of the mouth, reaching the insertion of the second pair of barbels; the second pair of barbels is thick and reaches the posterior edge of the eye; the anterior barbel length is 20.1-29.9%, and the second 29.7-39.5% of head length; the snout is prominent, with preorbital length 10.9-12.1% of standard length in females and 10.6-13.2% of standard length in males; the preorbital length is greater than the postorbital length (Ref. 107618). The dorsal fin is located posteriorly on the body, with the predorsal distance being 48.9-52.5% of standard length in females and 48.5-52.5% in males; the profile of the dorsal fin is concave, with the last single ray of the dorsal fin ossified with few and strong denticulations; dorsal fin with 3-5 unbranched rays and 8 branched rays; anal fin with 3 unbranched rays and 5 branched rays; pectoral fin with 1 unbranched ray and 15-16 branched rays; ventral fin with 1 unbranched ray and 6 branched rays; the caudal fin length is 20-23% of standard length in females and 18.4-24.5% of standard length in males (Ref. 107618). Number of scales on the lateral line 49-53; 8.5-9.5 scales above lateral line; 5.5-7.5 scales below lateral line (Ref. 107618). The caudal peduncle is elongated, and the least body depth is 11-11.9% of standard length in females and 9.5-11.8% of standard length in males; the length of the anal caudal peduncle is 2.1-2.3 times the height of the anal peduncle in females and 2.1-2.6 times in males (Ref. 107618). Pharyngeal teeth in adults 4.3.2 (Ref. 107618). Number of gill rakers 13-16; number of vertebrae 41-43 (Ref. 107618).Colouration: The colouration is brownish with a paler ventral area and some black spots along the body (Ref. 107618).
