簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 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).
與在 Akysis variegatus 種群 (除了 A. pictus, A. prashadi 與 A. varius) 中的它的同類有區分了沒有在胸棘的後緣上的鋸齒。 有別於 A. varius 在持有一個逐漸地分岔 (vs. 截形) 的尾鰭方面, 從 A. pictus 在有一個方面較大的眼 (12-16% HL vs.8-10) 與一個較小的脂鰭 (17.6-21.1% SL vs.22.0-23.6) 與從 A. prashadi 在有一個方面較大的眼 (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)
描述: 背鰭有 I,4,i ， I,5個鰭條 ; 臀鰭有 iii,4,i ， iii,6, iii,6,i ， iv,4,i ， iv,5, iv,5,i 鰭條; 胸鰭有我,6 歲, i ， I,7, 我,7 歲, i 鰭條; 腹鰭有 i,5個鰭條.(參考文獻 55399)
Occurs in clear, fast-flowing stream with a gravelly bottom (Ref. 55399).
出現於清澈又快速流動的水流具有一個多碎石的底部.(參考文獻 55399)
