Tenasserim white-bellied rat

The Tenasserim white-bellied rat (Niviventer tenaster) is a rodent in the family Muridae. It takes its common name from the Tenasserim Hills of Myanmar and lives in forested, limestone mountain country, typically above about 1,000 metres. Its range is patchy and mountainous, taking in India, Myanmar (the Arakan Mountains, the Dawna Range and the Bilauktaung range), Thailand, Cambodia, Laos, Vietnam (the Annamite Range) and southern China, including Yunnan and Hainan. The species was described by Thomas in 1916 and was for a time treated as a subspecies of another Niviventer rat until specimen studies showed it to be distinct. The Global Biodiversity Information Facility lists it as an accepted species, also known as the Indochinese mountain white-bellied rat, and records a Least Concern assessment from the IUCN Red List.
