Onychostoma brevibarba, a new cyprinid species, is described from two tributaries flowing into the Xiang Jiang (= River) of the middle Chang Jiang basin in Hunan Province, South China. The new species is morphologically similar to two Chinese congeners, O. minnanense and O. barbatulum, but differs from them in the anteromedian extension of the postlabial groove. It further differs from O. minnanense in the maxillary-barbel length, shape and body coloration, and from O. barbatulum in the number of lateral-line perforated scales and the width of the mouth opening. The validity of the new species and its close relationship with these two species were affirmed by a molecular phylogenetic analysis based on the mitochondrial cyt b and CO1 genes.
短须突吻鱼，一种新的鲤科鱼类，采自中国南方湖南省长江流域中部流入湘江的两条支流。该新物种在形态上与两种中国同属鱼类，即闽南突吻鱼和长须突吻鱼相似，但在后唇沟的前中位延伸方面与之不同。它在上颌须长度、形状和体色方面与闽南突吻鱼也有差异，在侧线穿孔鳞片数量和口裂宽度方面与长须突吻鱼不同。基于线粒体细胞色素b和CO1基因的分子系统发育分析证实了该新物种的有效性及其与这两个物种的密切关系。
