This widespread species is known from southern China, Viet Nam, Lao PDR, Cambodia, Thailand, central and northern Myanmar, northeastern India, Bhutan, and eastern Nepal (Musser and Carleton 2005). In China, it is known from the provinces of Tibet, Guizhou, Hainan (Guangdong), and Hong Kong (Smith and Xie 2008). It could possibly be present in the remnant northern and northeastern forests of Bangladesh (S. Molur pers. comm.). It is not known from mainland peninsular Thailand south of the Isthmus of Kra (10E, 30N), but it occurs on four islands off the coast (Koh Tau, Koh Phangan, Koh Samui, and Koh Kra) (Musser and Carleton 2005). It is also found on the Andaman Islands (islands of North Andaman, Interview, Middle Andaman, Long, Henry Lawrence, Havelock, South Andaman, and Little Andaman) and Car Nicobar (Musser and Carleton 2005). It roughly occurs from sea level (Aplin and Frost 2006) up to around 2,000 m asl (Sarker et al. 2005).
