The Anderson shrew mole ( Uropsilus andersoni ) is a species of mammal from the genus of the shrew mole ( Uropsilus ) within the insect eater (Eulipotyphla). The little-known species has so far only been found on Emei Shan in the Chinese province of Sichuan .
features
The Anderson shrew mole reaches a head-torso length of 6.5 to 8.3 centimeters and a tail length of 5.9 to 7.2 centimeters. The rear foot length is 14 to 17.5 millimeters. The back fur is dark brown in color, the coloration is darker than that of the other species of the genus.

The skull reaches a length of 21 to 22 millimeters. The animals have two incisors per half in the upper jaw , one canine , four premolars and three molars . The teeth in the lower jaw correspond to those in the upper jaw, but they only have three premolars there. Overall, the animals have a set of 38 teeth. The typical tooth formula is the main distinguishing feature from the other species of the genus.
distribution
The Anderson shrew mole is endemic to the Sichuan province in the People's Republic of China and has so far only been found on the Emei Shan and in its immediate vicinity. It occurs there partly sympatric with the Chinese shrew mole ( Uropsilus gracilis ) and the Sichuan shrew mole ( Uropsilus soricipes ).
Way of life
There is no information about the way of life of the Anderson shrew mole, like the other species of the genus, it lives on the ground and looks for small invertebrates there as food.
Systematics
The Anderson 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 Oldfield Thomas in 1911, who described the species on the basis of individuals from the Emei Shan in Sichuan, People's Republic of China. The species was partly assigned to the Sichuan shrew mole ( Uropsilus soricipes ), partly also incorporated into a separate, monotypical genus Rhynchonax . The species was named after the explorer and animal collector Malcolm Playfair Anderson , who collected it on a collecting trip on behalf of the Zoological Society of London and made it available to Thomas.
No subspecies are distinguished within the species.
Hazard and protection
The International Union for Conservation of Nature and Natural Resources (IUCN) does not assign the species to any risk level, but rather lists it as "data deficient" due to a lack of data. There is no data on the population figures, and there is no known risk.
