This species is present in central and eastern Nepal and also in parts of northeastern India (Sikkim, West Bengal and Meghalaya). It probably occurs more widely than current records suggest, especially in areas between known sites, and it can be expected to occur in Bhutan. It has been recorded from elevations between 1,000 and 2,000m asl.
Habitat and Ecology
While this species is known to inhabit mountain streams in forested areas, very little other information is available on its ecology or breeding habits. It presumably breeds in streams by larval development.
It is considered to be very rare, although no quantitative data exist.
Loss of forest surrounding streams, potential siltation of breeding sites, changes in water resource management (dam construction) and other infrastructure development are all major threats.
It has not been recorded from any protected areas. Recent field studies have been undertaken by Shresthra in Pashupati nagar (2001). It is protected by national legislation in India.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
