This species is present in northern Bangladesh, northeastern India (Meghalaya, Assam, Arunachal Pradesh and Sikkim), Myanmar and Peninsular Thailand (Bourret, 1941, Taylor, 1962). A record from Mao Son, in northern Viet Nam, was based on a misidentified Huia nasica (Bourret, 1941: 350). It occurs at elevations below 1,000m asl.
Habitat and Ecology
In South Asia this species is associated with riparian grasses and shrubs. Known occurrences in Southeast Asia are in evergreen forest near large streams in hill areas, usually within the vicinity of waterfalls. Tadpoles inhabit these large streams with boulders and sandy bottoms.
Adults are only occasionally encountered, but the distinctive tadpoles are impossible to overlook. Indications are that the species is not uncommon in areas where it occurs (P. van Dijk pers. comm). In Bangladesh the species is observed to be declining.
The species would be threatened by major impacts on forest streams such as clear cutting of forests or water diversion, but seems able to tolerate modest impacts from tourism in Southeast Asia.
The species is known to inhabit a number of protected areas in Peninsular Thailand, as well as several informally protected waterfall recreation areas. It has also been recorded from Madhupur National Park in Bangladesh and Mouling National Park and Dihang-Dibang Biosphere Reserve in India. It is protected by national legislation in India.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This form is probably a complex of more than one species (A. Ohler pers. comm.). The populations in Peninsular Malaysia probably refer to an undescribed species.
