This species is known from hilly areas in south-western China in Sichuan, Yunnan, Guizhou, and possibly Hunan Provinces, and from one location, Hoang Lien Son National Park, in northern Viet Nam (Ohler et al. 2000). It has been recorded from 1,150-3,200m asl.
Habitat and Ecology
It inhabits medium and small hill streams in montane forest, and sometimes also occurs near still-water pools. It may on occasion leave water to live in forest, shrubland and grassland, but it returns to breed in streams.
In China this species was formerly common, but it is now uncommon. In Viet Nam it was found to be relatively common in appropriate habitat (S. Swan pers. comm.)
The main threats to this species in China are over-collecting for local consumption, and habitat destruction and degradation due to shifting agriculture and smallholder farming (which might also be a threat in Viet Nam).
Some protected areas are present within the range of this species in China. The one known location in Viet Nam is within Hoang Lien Son National Park.
