From the IUCN Red List Species Account:


Range Description

This species ranges from India (West Bengal and Sikkim and smaller, isolated populations in Manipur and Arunachal Pradesh) and eastern Nepal through the Kachin and Shan Hills of Myanmar to western Yunnan (Longchuan county and its vicinity), China and scattered mountains in northern Thailand. It has recently been recorded from Lai Chau and Lao Cai Provinces in northwestern Viet Nam. It most likely also occurs in Lao People's Democratic Republic and Bhutan, although at present there are no known records. It probably occurs more widely than current records suggest, especially in areas between known sites. The boundary between this species and Tylototriton shanjing is not clear. In the southern part of its range it is generally an upland species occurring at elevations between 1,000-3,000 m asl. In the northern part of its range it is reported from low hills below 1,000 m asl.

Habitat and Ecology

Its terrestrial habitat is largely moist forest, with the animals generally remaining close to water. Aquatic habitats include various freshwater sources, including permanent pools, forest streams and even small waterbodies. Breeding occurs in the shallow areas of these waterbodies; there is little information on egg deposition although the larval stage is known to be relatively short. During the dry summer period animals may go into aestivation.


It is an uncommon species through most of its range, although it was reported locally common in Myanmar (Gyi 1969). Reports from different sites in northern West Bengal varied from less than 10 salamanders to hundreds of individuals per site (Hedge and Deuti 2007). It might be extinct in Viet Nam.

Population Trend


Major Threats

Habitat loss from infrastructure development and regular human-induced forest fires (in Southeast Asia) are a threat to this species. Water pollution from agrochemicals and domestic detergents, and the extraction of water for irrigation are also degrading its habitat. The species is considered a bad omen and thus killed in Myanmar in certain areas (Gyi 1969). It is used as bait for fishing in Myanmar and is in demand in the domestic and international pet trade. It is also harvested for use as a traditional medicine in India. In northern West Bengal, the flatlands in the Darjeeling Hills are being converted to housing and tourist complexes, while the slopes are being converted to tea estates. This region also suffers from livestock grazing, siltation and pollution (from pesticide runoff and domestic waste) of waterbodies and introduced carp (Hedge and Deuti 2007).

Conservation Actions

It is protected by legislation in Nepal, India, China and Thailand. Its range overlaps at least five protected areas in Thailand, one in China, one in India (Namttingpokkdi Wildlife Sanctuary, West Bengal) and one (Kanchanjanga Conservation Area) in Nepal. It has been bred in captivity in Europe.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Taxonomic Notes

There might be a nomenclatural problem with this species (A. Ohler pers. comm.).
