Range Description

This species is only known from Wuzhishan, Diaoluoshan, and Jianfengling in Hainan Province, China, from 770-950m asl. However, it is possible that some previous records of Tylototriton asperrimus from Vietnam (i.e., Nguyen and Ho, 1996) refer to this species (Böhme et al., 2005), but this requires verification.
