Differs from congeners from Java, Sumatra and Borneo by having the following unique combination of features: lateral line scales 30-31+3; absence of black blotch on end of caudal peduncle; absence of crescentric mark along posterior edge of scales; 2 barbels, less than eye diameter or absent; pectoral fin extending to or almost to the pelvic-fin origin; pelvic fin extending to anal-fin origin; dorsal-fin tip reaching behind vertical through anal-fin origin, when folded backwards; scale rows between lateral line and dorsal fin origin 5-6½; and curved sheath edge of lower jaw (Ref. 75626). Description: D iii,8½, the last two rays articulating on same pterygiophore ; A iii,5½ , the last two rays articulating on same pterygiophore; P i+16-17; V i+8 (Ref. 75626). |
