This species is known only from a tiny area on the island of Sumatra, Indonesia. The type locality is unspecified. It is apparently confined to Lubuk Selasi, at the head of the Terusan River at about 1,000m asl, on the borders of three districts, Padang Pariaman, Solok and Pesisir Selatan. Despite searches, it has not been found above 1,260m, or below 800m asl. Surveys in several other parts of Sumatra have failed to find this species, and it is likely to have a very restricted distribution.
Habitat and Ecology
It has been found along a small, clear stream with a width of 15m in secondary forest. No evidence of breeding has been found, but it presumably breeds by larval development in streams. It is not known whether or not the species is dependent on forest, though this is likely.
This species was rediscovered in 2001 after a gap of 141 years. At present, it is only known from one area, but is relatively abundant within its tiny range.
Since its rediscovery, there has been extensive and very rapid habitat destruction for rice paddies in its only known locality, leading to the siltation of streams, which might affect its ability to breed.
The species is not known from any protected area (it has not been recorded from a conservation forest about 10km from the only known locality). A community-based initiative involving local NGOs and communities is urgently needed to save the only known population of this species.
