The Yunnan shrew mole ( Uropsilus investigator ) is a species of mammal from the genus of the shrew mole ( Uropsilus ) within the insect eater (Eulipotyphla). The species is endemic to the Chinese province of Yunnan .
features
The Yunnan shrew mole reaches a head-trunk length of 6.7 to 8.3 centimeters and a tail length of 5.4 to 7.5 centimeters. The rear foot length is 13 to 16 millimeters. The species is very similar to the Chinese shrew mole ( Uropsilus gracilis ) and differs from it only in its size and the darker, almost black fur color and its distribution at higher altitudes.

The skull reaches a length of 20 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 there they only have one incisor. Overall, the animals have a set of 38 teeth. The tooth formula corresponds to that of the somewhat larger Chinese shrew mole and is the main distinguishing feature of these two from the other two species of the genus.
distribution
The Yunnan shrew mole is endemic to the Chinese province of Yunnan .
Way of life
As with all species of the genus, hardly any information is available about the way of life of the Yunnan shrew mole. The species occurs in open mountain pastures and spruce forests at an altitude of 3600 to 4600 meters. Like the other species of the genus, it lives on the ground and looks for small invertebrates there for food.
Systematics
The Yunnan 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 1922, who described the species on the basis of individuals from the high mountains of Yunnan. Some scientists assign the shape to the Chinese shrew mole ( Uropsilus gracilis ) as a subspecies, but others recognize it as a separate species.
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 endangerment 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.
