Vertèbres: 195 - 199. This species is distinguished by the following set of characters: body with numerous longitudinal wrinkles, with more than five longitudinal wrinkles on the posterior part of eye; head length 5.7-7.2% TL; tail length 65.7-67.5% TL; with two protrusions along the upper lip (rarely 1 on one side); dorsal-fin origin behind pectoral-fin tip by less than one pectoral-fin length; SO 1 + 3; POM 4-6 (usually 5) + 2; teeth on maxilla uniserial initially, becoming biserial posteriorly; vomerine and dentary teeth are biserial anteriorly, uniserial posteriorly; total vertebrae 195-199, MVF 15-63-197 (n = 9). Colouration: body bicolored; dorsal fin dark with a narrow margin entirely, anal fin pale except ending (Ref. 133101)
Cross section: circular.
Found in shallow water (Ref. 40865), collected adjacent to a river mouth (Ref. 133101). Probably spends most of the day in a burrow along the river bank and forages actively at night for small fishes (Ref. 12693); in soft bottom (Ref. 7300).
