A new blind species of the cave genus Oreonectes from Guizhou China (Nemacheilinae)

摘要

This study aimed to describe a new specimen of cavefish collected from a karst cave in the Daqikong area of Libo County, Guizhou. Twenty-six cavefish specimens were collected and identified as a new species of Balitoridae: Nemacheilinae, and named Oreonectes daqikongensis >sp. n. A genetic analysis was performed and showed that its genetic distances from Oreonectes shuilongensis and Oreonectes platycephalus are higher than intraspecific distances. Discovery of this species will be helpful to understand the distribution of Oreonectes.
