This species is known from eastern Nepa and from north-eastern India in West Bengal, Sikkim and Arunachal Pradesh Provinces, between 1,500 and 3,000m asl. It is presumed to occur in Bhutan.
Habitat and Ecology
It is associated with rocky streams and brooks in montane forests, and with pools in forest clearings. It needs moderate temperatures and high humidity. The tadpoles develop in streams.
The population status of this species is unknown.
It is generally threatened by habitat destruction as a result of localized deforestation and changes in waterway management (such as dam construction).
It is not known whether or not it occurs in any protected areas, although it is protected by national legislation in India. Recent field studies have been undertaken by Bordoloi in India in 2001 and by Shresthra in Nepal in 2001. Surveys are needed to determine more accurately its distribution (especially its probably occurrence in Bhutan), ecological requirements and conservation needs.
