Diagnosis

Distinguished from all its congeners by the following unique combination of characters: slender body (body depth at anus 8.2-10.3% SL; depth of caudal peduncle 3.5-4.5% SL); extremely narrow head (head width 17.5-20.2% SL); small and close-set eyes (eye diameter 6-10% HL; interorbital distance 20-26% HL); short nasal barbels (11-17% HL); the presence of 6-8 serrae along the posterior edge of the pectoral spine and 8-9 branchiostegal rays; and caudal fin strongly forked with pointed lobes (Ref. 30226).
