The De Winton shrew ( Chodsigoa hypsibia ) is a species of shrew from the genus Chodsigoa . It occurs mainly in the central south of the People's Republic of China .
features
With a head-torso length of 7.3 to 9.9 centimeters, the De Winton shrew is one of the small to medium-sized shrew species. The tail reaches a length of 60 to 80 millimeters and the rear foot 15 to 18 millimeters. The back color is uniformly brown-gray, the belly is a little more brown. The tail is gray on the upper side and white on the underside.

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 De Winton shrew is found in much of the central and southern People's Republic of China in the Hengduan Shan and Qin Ling areas, where it is endemic . It is widespread there in the provinces of Sichuan , Yunnan , Shaanxi , Xizang and Hebei as well as in Beijing and Gansu . The Hebei population is isolated from other occurrences.
The altitude distribution is normally 1200 to 3500 meters, in Hebei the population lives at an altitude of about 300 meters.
Way of life
As with all species of the genus, only a few data are available about the way of life of this species. Like all shrews, these species also feed on invertebrates. The habitat in the central elevations is very diverse and consists of ridges and deep valleys, the shrew lives in different vegetation areas, including forest and bushes.
Systematics
The De Winton shrew is classified as a separate species within the genus Chodsigoa , which consists of eight species. The first scientific description comes from William Edward de Winton from 1899, who described an individual from "Yang-liu-pa" in Sichuan.
Within the species, in addition to the nominate form Chodsigoa hypsibia hypsibia , no or one further subspecies are distinguished depending on the source. In the latter case, the isolated population in Hebei forms the subspecies C. h. larvarum while the nominate form populates the rest of the distribution area.
Threat and protection
The De Winton shrew 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 as well as the assumed population size and adaptability to different biotopes . Concrete population numbers and threats to the species are not known.
