This species is known from eastern Assam, northern Mizoram and Meghalaya in northeastern India, from Chittagong and Rangamati Hill-district in Bangladesh, and from the Bago Yoma Mountains and Tenasserim, in Myanmar (Bourret 1942). It is also reported from adjacent western Thailand (Nabhitabhata 1989), in Thong Pha Phum district and Sang Ksla Buri district, Kanchana Bui Province. An old record from central Viet Nam might be based on a misidentified specimen (Bourret 1942: 315) and is not included here. It probably occurs more widely than current records suggest, especially in areas between known sites. In Thailand it has been recorded from 600-700 m asl, but in India it is known only from below 500 m asl.
Habitat and Ecology
It is known from streams in evergreen forest, and is presumed to breed in streams.
It is reportedly uncommon in Thailand (T. Chan-ard pers. comm.), and relatively common where collected in Myanmar (G. Wogan pers. comm.). In Mizoram, India, it is considered moderately common during the rainy season (Lalremsanga et al. 2007).
Deforestation, fire impacts and agricultural encroachment might be a threat to this species.
It is known from Alaungdaw Kathapa National Park in northern Myanmar and Thung Yai Naresuan Wildlife Sanctuary and Thong Pha Phum National Park in Thailand. Re-evaluation of the taxonomic status and surveys of forest areas in its known range are desirable. It is protected by national legislation in India.
