The Dja-Schlitznase , also Ja-Schlitznase ( Nycteris major ), is a rare bat species of the genus of the Schlitznasen ( Nycteris ), which has so far been detected in West and Central Africa .
description
The Dja slit nose is about 12 g and an average forearm length 4.7 cm a small bat species. Outwardly, it resembles the Bate slit nose , which is slightly smaller and lighter than the Dja slit nose. The fur is brown on the top and bottom, the belly side looks lighter. The wings are also dark brown and 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.
distribution
The entire distribution area of the Dja slit nose is unknown; only a few specimens have been collected so far. They come from the Ivory Coast , Gabon , Benin , Liberia , Cameroon and the Democratic Republic of the Congo and in neighboring Zambia .
Way of life
There is little data available on the Dja slit nose, so that there are no reliable findings on the ecology of the species. Most of the specimens were caught in the lowland rainforest. Roosts were found in tree hollows of large trees, but also in buildings. Cyclops round-leaf noses ( Hipposideros cyclops ) were also found in some of the quarters . The species presumably hunts in forests, and when nets are caught, catches also reach low altitudes so that the animals can also collect their prey directly from the vegetation surface or the ground.
Etymology & Research History
The Dja slit nose was first described by Knud Christian Andersen under the name Petalia major . The bat was found near the river Dja , to which the name of the species indicates.
Danger
The IUCN does not carry out a risk assessment of the species because the data situation is too small (“data deficient”). Since the species occurs in the lowland rainforest and is rare, it is probably endangered by deforestation.
