From the IUCN Red List Species Account:
This species is known only from Doi [Nga] Chang, north of Chiang Mai city, in northern Thailand (Smith 1922; Taylor 1962). The type series was collected at 1,500m asl according to the original description, presumably at or near the top of the mountain, which is 1,462m high. It might occur more widely.
Habitat and Ecology
The habitat at the type locality is montane evergreen forest. This species presumably breeds by larval development in streams.
This species was first recorded in 1920, and has been recorded only once since, in the 1980s.
Possible threats to it might include shifting agriculture and water pollution from agricultural activity, although it is known that no logging occurs at this location.
Its one known locality is within Su Thep National Park. Assessment of the taxonomic status of this species, particularly its affinity to Chaparana palavanensis, C. fansipani, C. tweediei and C. nitida, and its generic assignment, would be desirable.
