Systematics
The Yunnan bush rat is classified as a separate species within the Hadromys genus , which consists of two species. The first scientific description was made by Yang Guangrong and Wang Yingxiang in 1987, they carried out this on the basis of individuals from the Ruili region in Yunnan province, which had been collected in 1985 at an altitude of 970 to 1300 m. In their first description, Yang and Wang classified the Yunnan bush rat as a subspecies of the Manipur bush rat ( Hadromys humei ). A specimen from the same region had already been examined in 1983 and, despite existing differences, was provisionally assigned to the Manipur bush rat.
Hazard and protection
The species is not classified in a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to a lack of knowledge about the population and the way of life, but is listed as "data deficient". There are no known threats to the stocks. In China the species is considered endangered.
