Like other Murina TYPES owned pets two front teeth (incisors), a canine (canine), two Vorbackenzähne (Praemolares) and three molars (Molar) in one half of the maxilla. In the lower jaw there is one more incisor per half of the jaw, a total of 34 teeth.

distribution

The dark tube-nosed bat is so far only known from the location of the type specimen ( terra typica ) in the Chinese province of Heilongjiang .

Way of life

No data are available on the habitat of the dark tube-nosed bat. The type specimen was caught in a house in September and probably wanted to hibernate there.

Systematics

The dark tube-nosed bat is assigned to the genus Murina as an independent species . The first scientific description comes from the naturalist Arthur de Carle Sowerby , who described the species in 1922 as a subspecies of the white-bellied tube-nosed bat ( Murina huttoni ) using an individual from Manchuria . It was later assigned to both the Hilgendorf tube-nosed bat ( Murina hilgendorfi ) and the reddish tube-nosed bat ( Murina leucogaster ), but described as independent due to clear differences to all known Murina species.

Apart from the nominate form, no subspecies are known within the species .

Hazard and protection

The species is not classified in a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to a lack of data on stocks and ecology, but is listed as "data deficient". There are no known threats to the species' existence.
