Needs updating
Assessor(s): Sabitry Bordoloi, Annemarie Ohler, Tej Kumar Shrestha

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.

Habitat and Ecology [top]

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.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

Conservation Actions: 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.
