Distribution area of the two subspecies of the Van Bemmelen bulldog bat

The Van Bemmelen bulldog bat , also known as the caudal gland bat ( Chaerephon bemmeleni ), is a species of bats from the genus of the free- tailed bat that occurs in Africa .

description

The head-trunk length of the Van Bemmelen bulldog bat is about 60 to 70 millimeters, the 34 to 40 millimeters long tail protrudes from the tail membrane. The fur is dark brown and short, the belly side a little lighter in color. The flanks are colored whitish. The color of the flight membranes and the tail membrane is gray. The tail membrane is hairless. It is named after the pouch-like glands located at the beginning of the tail in both sexes. These glands allow the bat species to be distinguished from all other species in the bulldog bat family . The ears are connected by a strip of skin, the upper lip is wrinkled. The small tragus is covered by a large antitragius.

Systematics & distribution

There are two subspecies:

Chaerephon bemmeleni bemmeleni ( Jentink , 1879) occurring in Guinea , Sierra Leone , Liberia , Ivory Coast and Cameroon
Chaerephon bemmeleni cistura ( Thomas , 1903) occurring in South Sudan , Uganda , the Democratic Republic of the Congo , in south-western Kenya and in northern Tanzania

Way of life

The Van Bemmelen bulldog bat is nocturnal and its roosts are probably in tree hollows and crevices in the rock. It occurs in the lowland rainforest as well as in various types of savannah, such as B. grass savannahs and tree savannahs.

Etymology & Research History

The species was first described in 1879 by Fredericus Anna Jentink under the name Nyctinomus bemmeleni . The name honors AA van Bemmelen, then director of the Rotterdam Zoological Garden, who provided the type specimen. The exact location of the holotype is unknown.

Danger

Due to the large distribution area, the presumably large population and the occurrence in protected areas, the IUCN does not consider the Van Bemmelen bulldog bat to be endangered (“least concern”).
