This species is recorded from India (Himanchal Pradesh, Uttaranchal, Nagaland, Meghalaya, Arunachal Pradesh and Assam), northern Bangladesh and much of Nepal. It probably occurs more widely than current records suggest, especially in areas between known sites. It has an altitudinal range of 1,000-2,500m asl.
Habitat and Ecology
It is associated with streams and riparian vegetation within tropical evergreen forest. Breeding takes place in streams. There is little available information on egg deposition or larval ecology.
It is generally considered to be rare.
There is a continuing loss of suitable stream habitats, through both deforestation and changes in water management (dams).
It has been recorded from Namdhapa National Park and Dibang Wildlife Sanctuary (both in Arunachal Pradesh). It is protected by national legislation in India. Recent field studies have been undertaken by Sabitri Bardoli and Maren Ao.
We follow Dubois (1992) and Schleich and Kästle (2002) in considering Amolops himalayanus to be a synonym of A. formosus.
