This species is known with certainty from Xinduqiao County, Sichuan Province, China. A second population from Zhendoushan might belong to this species. In general, this species might be more widespread, but further investigation is needed to confirm the identity of populations other than the Xinduqiao County population reported by Fu et al. (2001). It can be found at elevations of 1,800 to around 4,000m asl.
