简单描述
型态特徵 | 形态测量图
背的软条 (总数): 6-7; 臀鳍软条: 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).
藉由持有下列特征的一个独特组合与它的同类区分了: 36-38个脊椎骨, 最后的 2-3个肛门前而第一的 6-7 的强烈升高髓棘肛门后的脊椎骨，脂鳍基底 26.8-30.4% SL 的长度, 腹鳍达到第一个臀鳍鳍条的基底与那在身体上有灰白的斑点.(参考文献 55391)
描述: 背鳍有 i,5, i,5,i 或 i,6个鳍条; 臀鳍有 iv,7, iv,8, v,6, v,6,i, 或 v 7个鳍条; 胸鳍有 i,12, i,13, 否则 i,14个鳍条; 腹鳍有 ii,5个鳍条.(参考文献 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).
