Abstract:
Triplophysa xuanweiensis sp. nov., a new blind loach species from the family Nemacheilidae, is described based on specimens collected from a subterranean river in Xuanwei City, Yunnan Province, China. The new species can be distinguished from all known congeners by a combination of the following characters: eyes absent, dorsal-fin origin anterior to pelvic-fin origin, tip of pelvic fin reaching anus, dorsal fin with 7–8 branched rays, caudal fin forked with 16–18 branched rays, body scaleless and colorless, lateral line complete, and posterior chamber of air bladder well developed and connected to anterior chamber by long, slender tube. Maximum-likelihood phylogenetic analysis based on the cytochrome b (cyt b) gene placed Triplophysa xuanweiensis sp. nov. in a well-supported clade with seven other species of the genus, and three specimens of the new species formed a monophyletic group, consistent with morphological comparisons
