This species is patchily distributed from Pakistan and northern India, through Nepal, Myanmar, Thailand, Lao PDR, Cambodia, Viet Nam and southern China (Anning and Ruili, both localities in Yunnan [Smith and Xie 2008]) (Musser and Carleton 2005). It has also been recorded from northern Sumatra and central and eastern Java, both to Indonesia, where it may represent either introduced or natural, relictual populations (Ken Aplin pers. comm.). It is found from sea level to roughly around 2,000 m asl.
