The Sichuan shrew mole ( Uropsilus soricipes ) is a species of mammal from the genus of the shrew moles ( Uropsilus ) within the insect eater (Eulipotyphla). The species is endemic to the People's Republic of China .
features
The Sichuan shrew mole reaches a head-trunk length of 6.6 to 8.0 centimeters and a tail length of 5.0 to 6.9 centimeters. The rear foot length is 14 to 17 millimeters. As with all species of the genus, the back fur is dark brown in color, the belly is iron gray and the outside of the feet and the top of the tail correspond to the back coloration.

The skull reaches a length of 21 to 22 millimeters. The animals have two incisors per half in the upper jaw , one canine , three premolars and three molars . The teeth in the lower jaw correspond to those in the upper jaw, but there they only have one incisor. Overall, the animals have a set of only 34 teeth while all other species of the genus have 38 teeth. The typical tooth formula is the main distinguishing feature from the other species of the genus.
distribution
The Sichuan shrew mole is endemic to the People's Republic of China . He can be found in the provinces of Gansu , Sichuan , Yunnan and Shaanxi .
Way of life
As with all species of the genus, there is hardly any information about the way of life of the Sichuan shrew mole. Like the other species of the genus, it lives on the ground and looks for small invertebrates there for food. In Wenchuan , the species occurs sympatric with the Chinese shrew mole ( Uropsilus gracilis ), there it lives below 2200 meters altitude, while the Chinese shrew mole occurs above 3000 meters.
Systematics
The Sichuan shrew mole is classified as an independent species within the shrew mole (genus Uropsilus ), which consists of four species and is assigned to the moles . The first scientific description was made by Alphonse Milne-Edwards in 1872, who described the species and the genus using individuals from Sichuan. In some cases, all other species of the genus were assigned to this species, but today they are considered independent.
No subspecies are distinguished within the species.
Hazard and protection
The species is listed as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). This is justified by the comparatively wide distribution and the assumed high populations, the occurrence in several protected areas and the only slight decline in populations . There are no known risks to the company's existence.
