Range DescriptionThis species is found in Cambodia, south-western China (Guangdong, Guangxi, Guizhou, and Yunnan provinces), north-eastern India (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura provinces), Lao PDR, north-western Peninsular Malaysia, northern Myanmar, Thailand, and Viet Nam. It appears to be absent from most of Myanmar and Thailand; records are only from the far north of Myanmar and from the border ranges between the two countries south into the peninsula, with a few dubious records in central and north-western Thailand. It was formerly found in eastern Bangladesh as well, but may now be extinct there. In China it is found south of 25Â°N. The species has been introduced to Hong Kong. In north-eastern India, it has long believed to be restricted to the south bank of the Brahmaputra River (Choudhury 1988), yet Srivastava and Mohnot (2001), J. Das (pers. comm.) and Chetry et al. (2003) report possible records of this species from Namdapha National Park, though they were morphologically distinct from other representatives of the species, and could represent an undescribed subspecies.
