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.
Habitat and Ecology
It inhabits forests and breeds in pools and seepage pools. The larvae develop in water.
It is uncommon.
The major threat to this species is habitat loss and degradation due to agriculture, clear-cutting and infrastructure development for tourist activities.
All three known locations of this species are within protected areas: Wuzhishan, Jiangfenling and Diaoluoshan National Nature Reserves.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2 and its Area of Occupancy is probably less than 500km2, with all individuals in fewer than five locations, and the extent of its habitat is probably declining.
The taxonomic validity of this species is disputed.
