This species is known only from Jingdong and Yongde counties in south-western Yunnan Province, China, from 1,400-2,400m asl. It might occur a little more widely than records suggest.
Habitat and Ecology
It inhabits the forest floor of evergreen broadleaf forests. It breeds in the head of streams and the larvae are then washed some distance downstream.
It is a very rare species.
The major threat to this species is habitat loss and degradation due to agriculture (including plantations) and subsistence wood collection.
The range of this species includes the Great Snow Mountain National Nature Reserve (Yongde County), and the Wuliangshan National Nature Reserve (Jingdong Country).
