摘　　要：A new spined loach, Cobitis gracilis sp. nov., is described based on specimens collected from Jilin and Heilongjiang Provinces, China. Morphological and molecular data showed that C. gracilis sp. nov. is closely related to C. granoei Rendahl and C. melanoleuca Nichols. The new species differs from its sister species in lamina circularis, suborbital spine, and pigmentation at the base of caudal fin. In addition, both morphological and molecular analyses revealed that specimens of C. lutheri Rendahl from China differs from those from Korea. Korean specimens are appropriately placed in a separate species. Molecular analyses revealed that C. choii Kim ＆ Son is a new record in China.A new spined loach, Cobitis gracilis sp. nov., is described based on specimens collected from Jilin and Heilongjiang Provinces, China.
