The Lowe shrew ( Chodsigoa parca ) is a species of shrew from the genus Chodsigoa . It occurs in parts of the People's Republic of China as well as in northern and eastern Myanmar , northern Thailand and northern Vietnam .
features
With a head-torso length of 6.8 to 8.4 centimeters and a weight of 7 to 9.5 grams, the Lowe shrew is one of the medium-sized shrew species. The tail reaches a length of 74 to 108 millimeters and is therefore significantly longer than the body, the rear foot is 15 to 20 millimeters long and the ear length is 8 to 10 millimeters. The back and belly color is slate gray with a brownish tinge, whereby the belly is a little lighter. The tail is brown on top and creamy white underneath; it appears naked, but is covered with short, brown hair that ends in a tuft at the tip of the tail. The tops of the feet appear creamy white through the skin and are given a light brownish color by the brown hair. Compared to the very similar looking Chodsigoa smithii , the species is a little smaller and a little lighter in color.

The skull of Chodsigoa parca has a length of 19 to 21 millimeters, the brain skull is clearly bulged. Compared to Chodsigoa smithii , the snout area is narrower and less tapered in the area of the premaxillary . Like all species of the genus has the type in the maxilla per half an incisor (incisor) and then three unicuspid teeth, a Vorbackenzahn (premolar) and three molars (molar). In the lower jaw, however, it has a single canine behind the incisor. In total, the animals have a set of 28 teeth. The tooth roots are colored red as in most red-toothed shrews.
distribution
The Lowe shrew is found in parts of the People's Republic of China in the provinces of Sichuan , Yunnan and Guizhou, as well as in northern and eastern Myanmar , northern Thailand and northern Vietnam . In addition, occurrences in Laos are assumed, where the species has not yet been proven.
The altitude distribution for the species is between 1500 and 3000 meters. In Vietnam, heights of 1500 to 2000 meters in the area of the Tay Con Linh II mountain near the Chinese border were documented, in Yunnan animals were detected up to 3000 meters. In Chodsigoa smithii the species lives largely allopatric , but a sympatric occurrence has been proven for at least one locality . In Vietnam it comes from the same site as the Chodsigoa caovansunga that was first described from there .
Way of life
As with most other Asian shrews, very little data is available on the way of life of this species. Like all shrews, the Lowe's shrew feed on invertebrates and live on the ground. In Vietnam, the animals were found in bamboo forests .
Systematics
The Lowe shrew is classified as a separate species within the genus Chodsigoa , which consists of eight species. The first scientific description comes from Glover Morrill Allen from 1923 on the basis of an individual from the west of the Chinese province of Yunnan. The species was classified as a subspecies of Chodsigoa smithii for a long time , but since the 1980s it has been given species status again.
Within the species, in addition to the nominate form Chodsigoa parca parca , Chodsigoa parca furva and Chodsigoa parca lowei, two further subspecies are distinguished.
Threat and protection
The Lowe's shrew is classified by the International Union for Conservation of Nature and Natural Resources (IUCN) as “least concern” due to its relatively large distribution area and the assumed size of the population. Concrete population numbers and threats to the species are not known; a potential hazard could arise from clearing forests.
