Three new species of Cobitis C. fasciola sp. nov., C. crassicauda
sp. nov. and C. stenocauda sp. nov. are found from the River Xinjiang and the River Le’anjiang, tributaries of Lake Poyang, belonging to the River Yangtze system, Jiangxi Province, China. These cobitid fish are described based on the morphology features such as the pigmentation pattern, shape of lamina circularis, body scales, mouth character and sequences of mitochondrial cytochrome b (cyt b) gene, which can be used for molecular identification and diagnosis of these species. Illustrations of the morphology characters of new species are given, and phylogenetic analysis identifies
deoxyribonucleic acid (DNA) lineages closely related to these cobitid fish. Traditional taxonomy of cobitid fish of the subfamily Cobitinae is discussed based on the recent molecular phylogenies of these cobitid fish.
