Blarinella griselda is a species of shrew from the genus Asian short-tailed shrews ( Blarinella ). It occurs in a large part of the People's Republic of China as well as in northern Vietnam .
features
With a head-trunk length of 5.2 to 7.9 centimeters, the species is one of the small to medium-sized shrew species and lies within the genus between the other two species Blarinella wardi and Blarinella quadraticauda . The tail reaches a length of 31 to 42 millimeters and the hind foot of 8 to 14 millimeters; as with all species of the genus, the tail is very short. The species corresponds to Blarinella quadraticauda in its appearance , but is somewhat smaller. The back and belly color are uniformly dark gray to brown, with the belly side and the tail being slightly lighter. The top of the fore and hind feet is brownish.

The skull has a maximum length of 19 to 21 millimeters. Like all species of the genus has the type in the maxilla per half an incisor (incisor) and then five unicuspid teeth, a Vorbackenzahn (premolar) and three molars (molar). In the lower jaw, however, it has a single canine behind the incisor. The animals have a total of 32 teeth.
distribution
Blarinella griselda occurs in a large part of the People's Republic of China in the provinces of Gansu , Hubei and a larger part in southwest Yunnan . The species is also documented in northern Vietnam in the area of Tay Con Linh II. Possible occurrences could also exist in Myanmar and northern Laos .
Way of life
As with all species of the genus, hardly any data is available on the way of life of this species. Like all shrews, these species also feed on insects. It is believed that the species is primarily found in wooded habitats. In Vietnam, individuals have been found in bamboo forests at altitudes of 1500 to 1700 meters.
Systematics
Blarinella griselda is classified as an independent species within the genus of the Asian short-tailed shrew ( Blarinella ), which consists of three species. The first scientific description comes from Oldfield Thomas from 1912. At times the species was assigned to the Blarinella quadraticauda just like Blarinella wardi .
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 not endangered ("least concern") due to its relatively large distribution area and the assumed population size. Threats to the species are unknown and a significant decline in populations is not assumed. If there is a link to forest habitats, local threats can arise from clearing and habitat changes.
