The Bowers white-toothed rat ( Berylmys bowersi ) is a species of mammal from the genus of the white-toothed rat ( Berylmys ) within the rodents (Rodentia). It occurs from the south of the People's Republic of China to Southeast Asia and Sumatra .
features
The Bowers white-tooth rat reaches a head-trunk length of 23.6 to 28.5 centimeters and a tail length of 24.9 to 29.2 centimeters with a weight of up to 420 grams. The rear foot length is 48 to 61 millimeters and the ear length 32 to 36 millimeters. It is the largest species of the genus. The back fur is matt brown-gray, the peritoneum white. The tail is slightly longer than the rest of the body, it is mostly dark brown with a white tip or evenly dark brown. The tops of the fore and hind feet are also dark brown, but the toes and sides are white. The females have four pairs of teats , one each in the chest and stomach area and two in the groin area . The skull has a length of 52.0 to 58.5 millimeters.
distribution
The Bowers white-toothed rat occurs from the south of the People's Republic of China to northeast India and to Southeast Asia and Sumatra . In China it is only found in southern Yunnan and Sichuan as well as in Zhejiang and Fujian . In Southeast Asia it lives in northern to central Myanmar , Thailand , northern Laos , Vietnam , the Malay Peninsula and in the north of the Indonesian island of Sumatra, where it was found in Medan . The altitude distribution ranges from about 800 to about 1800 meters.
Way of life
The Bowers white-toothed rat lives mainly in primary forest areas of the lower mountainous region, but can also occur in secondary forests and bushes, and occasionally occurs in agricultural areas and at the edges of forests . It is nocturnal and mainly living on the ground, but can also climb. She spends the day in large underground burrows, which she digs mainly between rocks, under piles of wood and tree roots or along streams and paths. The species feeds primarily herbivorous of fruits and seeds, but it can also eat insects and snails.
Systematics
The Bowers white-toothed rat is classified as an independent species within the white-toothed rat (genus Berylmys ), which consists of four species. The first scientific description was made by the zoologist John Anderson in 1878 from the Kakhyen Hills in the south of the Chinese province of Yunnan . He assigned the species to the mice of the genus Mus as Mus bowersii .
The species was named after the merchant and ship owner Captain Alexander Bowers , who was probably involved in the execution of Edward Sladen's expedition through Burma (now Myanmar ) to China in 1868 , on which Anderson also traveled.
Hazard and protection
The species is listed by the International Union for Conservation of Nature and Natural Resources (IUCN) as not endangered (least concern). This is justified with the large distribution area, the large populations of the species at least in regions with sufficient tree populations and the occurrence in numerous protected areas. There are no known threats to the existence of the species; in some parts of the distribution area, forest loss could pose a regional threat.
