Distinguished from its congeners in the Akysis variegatus species group (except for A. pictus, A. prashadi and A. varius) in having no serration on the posterior edge of the pectoral spines. Differs from A. varius in possessing a gently forked (vs. truncate) caudal fin, from A. pictus in having a larger eye (12-16% HL vs. 8-10) and a smaller adipose fin (17.6-21.1% SL vs. 22.0-23.6) and from A. prashadi in having a larger eye (12-16% HL vs. 8-12) and a longer caudal peduncle (19.4-23.3% SL vs. 16.5-18.4) (Ref. 55399). Description: Dorsal fin with I,4,i, I,5 rays ; Anal fin with iii,4,i, iii,6, iii,6,i, iv,4,i, iv,5, iv,5,i rays; Pectoral fin with I,6,i, I,7, I,7,i rays; Pelvic fin with i,5 rays (Ref. 55399). |
