This species is only known with certainty from northern Bengkulu Province, Sumatra, Indonesia, where it occurs at low altitudes. It has not been found in West Sumatra, despite attempts to locate it there. There is an old record from Nias Island but there are doubts that the locality of this specimen has been correctly recorded.
Habitat and Ecology
It lives in lowland forest, but it is not known whether or not it can adapt to secondary habitats. It probably breeds by larval development in slow-flowing streams.
It is probably rare, since a number of expeditions have collected only a few specimens, and it probably occurs at low densities.
The primary threat is likely to be habitat conversion due to smallholder farming and logging activities.
Although it is known to occur in forest in a recreational area for tourists, expanded protection of lowland forest habitats is clearly necessary.
Red List Status
Listed as Endangered, because its extent of occurrence is less than 5,000 km2 and its area of occupancy is less than 500 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its habitat in Bengkulu Provice, Sumatra.
