This species is known from two localities in Thailand: the type locality in Doi Inthanon, and Thongphaphum, in Kanchanaburi Province. It has only recently been discovered, and is cryptic and easily overlooked and might be found to be more wide-ranging. It has been recorded between 930 and 1,650m asl.
Habitat and Ecology
This species inhabits forest on sloping land, generally in the vicinity of small streams. It breeds in waterfalls, and the larvae develop in the water.
It is apparently not rare in suitable habitat (Matsui et al. 1998).
The type locality is a national park, but this area is under some threat from habitat degradation through agricultural encroachment. This species is used in medical research, but it is not collected at a level that constitutes a threat. The American bullfrog (Rana catesbeiana) has also been deliberately introduced to this region and does pose a potential threat.
Regarding this species' conservation, the type locality is within Doi Inthanon National Park, while the second known locality is from an area that is being proposed as a national park, but improved protection and management are recommended. Studies of its population status, distribution and natural history are needed, and ecological studies are ongoing.
