The dwarf slot nose ( Nycteris nana ), also dwarf nose slot is a in West and Central Africa occurring bat species of the genus of nycteridae .
description
With an average weight of about 5 to 6 g, the dwarf slit nose is a small representative of the genus of slit nose . The fur is dark brown above and below, the dark brown wings are hairless. The ears are wide and rounded, and the outer edge of the tragus is concave halfway along its length. As with other slit noses, the face above the muzzle appears to be divided into two by a longitudinal furrow. The forearm length is less than 3.7 cm on average, which means that it can be distinguished from the closely related and similar-looking species Middle slit nose (forearm length 3.6 - 3.8 cm) and Bate slit nose (forearm length over 3.8 cm).
distribution
The dwarf slit nose is common in the rainforests of Central and West Africa. The large distribution area extends from the Ivory Coast in the west via Togo , Cameroon and the Democratic Republic of the Congo to Uganda in the east. The southern limit of distribution is in northern Angola .
Way of life
The preferred habitats of the dwarf slit nose are lowland rainforests and adjacent forest areas. Quarters are occupied individually or in small family groups. The roosts are in tree hollows, the entrance of which is close to the ground.
Research history
The type specimen was collected by George Latimer Bates in the Congo and first described by Knud Christian Andersen under the name Petalia nana in 1912.
Danger
The IUCN has classified the species as not endangered (“least concern”) due to its large distribution area and the presumably large population size.
