This species is widespread throughout southern China and south-east Asia. It is known from Okinawa Island, Japan (it is not known whether this population was introduced (Abe et al. 2005)) to Taiwan, Province of China, southern China (Yunnan, Guizhou, Guangxi, Guangdong, Fujian, Hainan Island, and Hong Kong provinces) (Smith and Xie 2008), Viet Nam, Lao PDR, Cambodia, and Thailand (Musser and Carleton 2005). It has also been recorded from the Malay Peninsula, and in Indonesia in Sumatra, Java, Madura and Flores Islands in Nusa Tenggara; all places where they may possibly have been inadvertently introduced (Musser and Newcomb 1983), but they may also represent relictual populations (although those on Flores are definitely introductions). The spotty distribution of this species on the Sunda Shelf is best explained by inadvertent human introductions (Musser and Newcomb 1983).
