背棘 (总数) : 1; 背的软条 (总数) : 5; 脊椎骨: 31 - 32. 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).
Body shape (shape guide): elongated.
与在 Akysis variegatus 种群 (除了 A. pictus, A. prashadi 与 A. varius) 中的它的同类有区分了没有在胸棘的后缘上的锯齿。 有别于 A. varius 在持有一个逐渐地分岔 (vs. 截形) 的尾鳍方面, 从 A. pictus 在有一个方面较大的眼 (12-16% HL vs.8-10) 与一个较小的脂鳍 与从 A. prashadi 在有一个方面較大的眼 (12-16% HL vs.8-12) 與一個較長的尾柄 (19.4-23.3% SL vs.16.5-18.4).(參考文獻 55399)
