| Diagnosis |
Differs from congeners from Java, Sumatra and Borneo by the combination of following features: lateral line scales 30-31+2-3; absence of black blotch on end of caudal peduncle; specimens about 10 cm SL with faint midlateral stripe, posteriorly slightly more distinct, extending on median caudal rays; presence of crescentric mark (apex pointing backwards) on posterior half of exposed scales; 4 barbels in about 13 cm SL specimens, mandibullary ones about smaller than eye diameter, snout ones minute, barely distinct, larger in adults; pectoral fin extending about ¾ of distance to pelvic -fin origin; pelvic fin extending between anus and anal-fin origin; dorsal-fin tip reaching extending vertical through anal-fin origin, when folded backwards; scale rows between lateral line and dorsal fin origin 5½; and arched sheath edge of lower jaw (Ref. 75626). Description: D iii,8½, iii,9½, the last two rays articulating on same pterygiophore ; A iii,5½ , the last two rays articulating on same pterygiophore; P i+15, i+16; V i+8 (Ref. 75626). |
