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 Yunnan pygmy shrew has so far only been found in the Likiang chain in the west of the province of Yunnan , from where the type specimen of the first description comes.
The altitude distribution is probably around 3000 meters.
Way of life
No data are available on the way of life of this species. Like all shrews, the species of the genus Chodsigoa also feed on invertebrates.
Systematics
The Yunnan pygmy 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, who described an individual from the Likiang chain in western Yunnan Province . The species was originally regarded as a subspecies or synonym of the Gansu shrew ( Chodsigoa lamula ), but the species status has now been confirmed.
Apart from the nominate form Chodsigoa parva parva, no further subspecies are distinguished within the species .
Threat and protection
The International Union for Conservation of Nature and Natural Resources (IUCN) does not classify the Yunnan pygmy shrew in any endangerment category, as hardly any data on the species are available (“data deficient”). Concrete population numbers and threats to the species are not known.
