Anourosorex squamipes is a species of shrew from the genus of the stubby- tailed shrews ( Anourosorex ). It is common in South and Southeast Asia from central China to northern Vietnam, Myanmar and Thailand.
features
With a head-torso length of 7.4 to 11 centimeters, the species is one of the medium-sized shrew species. The tail reaches a length of 8 to 19 millimeters and the hind foot from 11 to 16 millimeters; as with all species of the genus, the tail is very short and thin. The back and belly color are uniformly dark gray to brown, the belly side is only slightly lighter, and the fur is very dense and loose. The front feet have clearly enlarged claws.

The skull has a maximum length of 23 to 26 millimeters. Like all species of the genus has the type in the maxilla per half an incisor (incisor), two canine teeth (canines), a Vorbackenzahn (premolar) and three molars (molar). The number of canines is reduced in the lower jaw (one instead of two in each half). The animals have a total of 26 teeth. The third molars are reduced in both the upper and lower jaw.
distribution
Anourosorex squamipes is distributed over parts of South and Southeast Asia from central China via East India and Bhutan to the north of Vietnam , Myanmar , Laos and Thailand . In India there is only evidence of an occurrence in the state of Mizoram , in China the species lives in the provinces of Gansu , Shaanxi and from Hubei to Yunnan .
Way of life
The preferred habitat of Anourosorex squamipes is at medium altitudes of 1200 to 3000 meters, where it mainly inhabits mountain forests of various types. Like other species of the genus, the species is adapted to a subterranean way of life, but some of its food is found in the soil. As with other shrews, this consists of insects, worms and other invertebrates. Hardly any data are available on reproduction.
Systematics
Anourosorex squamipes is classified as a separate species within the genus of the stubby-tailed shrews ( Anourosorex ), which consists of four species. The first scientific description comes from Henri Milne-Edwards from 1872. Originally, all species of the genus were grouped together to form this species and the genus was accordingly regarded as monotypical ; today, in addition to Anourosorex squamipes , Anourosorex assamensis , Anourosorex schmidi and Anourosorex yamashinai are valid species.
Apart from the nominate form, no subspecies are distinguished within the species .
Threat and protection
The species is classified by the International Union for Conservation of Nature and Natural Resources (IUCN) as “least concern” due to its relatively large distribution area in Asia and the assumed population size. Threats to the species are unknown and a significant decline in populations is not assumed.
