簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 6-7; 臀鰭軟條: 11 - 12; 脊椎骨: 36 - 38. Distinguished from its congeners by possessing a unique combination of the following characters: 36-38 vertebrae, strongly elevated neural spines of the last 2-3 preanal and first 6-7 postanal vertebrae, length of adipose-fin base 26.8-30.4% SL, pelvic fins reaching the base of the first anal-fin ray and the presence of pale spots on the body (Ref. 55391).
藉由持有下列特徵的一個獨特組合與它的同類區分了: 36-38個脊椎骨, 最後的 2-3個肛門前而第一的 6-7 的強烈升高髓棘肛門後的脊椎骨，脂鰭基底 26.8-30.4% SL 的長度, 腹鰭達到第一個臀鰭鰭條的基底與那在身體上有灰白的斑點.(參考文獻 55391)
描述: 背鰭有 i,5, i,5,i 或 i,6個鰭條; 臀鰭有 iv,7, iv,8, v,6, v,6,i, 或 v 7個鰭條; 胸鰭有 i,12, i,13, 否則 i,14個鰭條; 腹鰭有 ii,5個鰭條.(參考文獻 55391)
Found in broad and shallow, well-oxygenated riffles with swift water velocities over rocky substrate (Ref. 55391). Feeds on aquatic insects (Ref. 55391). May spawn in upper reaches of rivers, then migrate downstream following spawning season (Ref. 55391).
