A new loach species (Cypriniformes: Nemacheilidae: Yunnanilini), , was caught from Chuanhe in the upper reaches of the Lixianjiang River, a tributary of the Red River in Nanjian County, Yunnan Province, China. This species is a member of the traditional species group based on the presence of a lateral line and cephalic lateral-line canals. It can be distinguished from other species in the species group by the following characters: lips without papillae, anterior and posterior nostrils separated, whole body scaled, eye diameter smaller than interorbital width, outer gill raker absent on first gill arch, eye diameter greater than 18% of head length, 10-11 inner gill rakers on first gill arch, and lateral line not extending to vertical through dorsal fin insertion. To the best of our knowledge, this is the first species recorded from the Red River drainage.
一种新的泥鳅物种（鲤形目：条鳅科：云南鳅属）， ，于云南省南涧县李仙江上游的川河被捕获。该物种是传统的 物种组的成员，其特征为存在侧线和头部侧线管。它可以通过以下特征与 物种组的其他物种区分开来：嘴唇无乳突，前鼻孔和后鼻孔分开，全身有鳞片，眼睛直径小于眼间距，第一鳃弓上没有外鳃耙，眼睛直径大于头部长度的 18%，第一鳃弓上有 10-11 个内鳃耙，侧线不延伸到通过背鳍插入处的垂直方向。据我们所知，这是红河流域首次记录到的 物种。
