This species inhabits various types of moist evergreen forest, including monsoon and perennial rainforest types, being generally associated with hilly regions (Dring 1979, Inger et al. 1999, Stuart 1999, Berry 1975), and often found near streams (Stuart 2005). It also occurs in secondary growth. Breeding mainly takes place in still pools by larval development.

This species ranges from southern Yunnan Province (Jinghong, Mengla and Mengyang counties) in China and northeast India including Arunachel Pradesh, Assam, Manipur, Mizoram, Tripura, and Meghalaya, into central, northeastern and southeastern Bangladesh (Khan 2018), through Myanmar, Thailand, Lao People's Democratic Republic (Lao PDR), Cambodia, and central and southern Viet Nam, south into Peninsular Malaysia and Indonesia, including Sumatra and parts of Borneo. Subpopulations in Bangladesh are in need of review, as Hasan et al. (2012) suggested on the basis of molecular evidence that these subpopulations represent an unnamed species. However, this has not yet been confirmed. The presence of this species is uncertain in Brunei Darussalam and Bhutan, and the species is absent from Singapore. The only recorded island occurrence is on Langkawi (Berry 1975), in Malaysia. This species occurs at elevations ranging from sea level up to 1,200 m asl.

Conservation Actions
The range of this species includes several protected areas, as most of its range lies within protected areas. This species is on the "List of Beneficial or of Important Economic or Scientific Value Terrestrial Wild Animals under States Protection", under the protection of the "Law of the People's Republic of China on the Protection of Wildlife", which provides a moderate degree of protection and makes it illegal to collect (China Red List Assessment Workshop June 2019).

Research Needed
The resolution of the taxonomic status of this complex is needed.
