Triplophysa ferganaensis sp. nov. is described from the Shakhimardan stream, a small tributary of the Syr Darya, which does not reach the river in Fergana Valley. It can be distinguished from other valid Triplophysa loaches based on the following combination of characters: body smooth and scaleless, lateral line complete, posterior chamber of air bladder degenerated, inner gill rakers 10-11 on the first-gill arch, outer gill rakers absent, vertebrae 4 + 35-36, 8 + 8 branched caudal-fin rays, caudal peduncle depth 2.1-2.7 times its length, two supratemporal pores, dorsal-fin origin closer to the caudal-fin base than to the snout tip, caudal fin emarginated and pelvic-fin tip reaching the anus. The new species can also be distinguished from its congeners based on the molecular analyses of mitochondrial cytochrome oxidase subunit I (coI) gene sequences. The phylogenetic position of this new species indicates that it is a sister taxon of Triplophysa tenuis.
新疆高原鳅（Triplophysa ferganaensis sp. nov.）是从锡尔达里亚河（Syr Darya）的一条小支流沙赫里马尔丹溪（Shakhimardan stream）中描述的，这条支流并未到达费尔干纳山谷（Fergana Valley）的河中。它可以通过以下特征组合与其他有效三须高原鳅（Triplophysa loaches）区分开来：身体光滑无鳞，侧线完整，气囊后室退化，第一鳃弓上的内鳃耙 10-11 个，外鳃耙缺失，椎体 4+35-36，8+8 分支尾鳍鳍条，尾柄深度为其长度的 2.1-2.7 倍，有两个颅顶孔，背鳍起点比吻尖更靠近尾鳍基部，尾鳍截形，臀鳍末端到达肛门。该新种还可以通过线粒体细胞色素氧化酶亚基 I（coI）基因序列的分子分析与其同属种区分开来。这个新种的系统发育位置表明它是细尾高原鳅（Triplophysa tenuis）的姊妹分类群。
