The Chapin bulldog bat ( Chaerephon chapini ) is a species of bat of the cantilever bat genus found in sub-Saharan Africa .
description
The Chapin bulldog bat is a small species of bat that weighs around 10 g. The forearm length is between 38.3 and 42.0 mm. The body length including the tail is between 94.8 and 103 mm. The fur is white on the underside, the back is light gray to light brown. The wings are white. The upper lips are wrinkled, the ears have grown together. The tail protruding from the tail membrane is characteristic of the genus of the cantilever bats. There is a morphological difference between the sexes : males have a 12 to 15 mm long, two-colored tuft on their heads. This is darkly colored at the roots of the hair, the ends of the hair are white. The forelock is usually flat, but can be raised like a mohawk . In females, the forelock is monochrome and only about 3 to 5 mm long. The species can be distinguished from the other free-tailed bats in Africa by a forearm length of usually less than 40 mm and the head of hair.
Systematics & distribution
The Chapini bulldog bat is widespread in sub-Saharan Africa. Two subspecies are sometimes distinguished:
- C. c. chapini , found in the Democratic Republic of the Congo , Ivory Coast , Sudan to Angola
- C. c. lancasteri (RW Hayman 1937), occurrence in southern Africa: Zambia and Zimbabwe
The division into two subspecies is not shared by all authors, Monadjem et al. do not consider the population found in Zambia and Zimbabwe to be a subspecies. At times, Chaerephon shortridgei was listed as a further subspecies of the Chapini bulldog bat.
Way of life
In southern Africa, individuals of the Chapini bulldog bat were caught in mopane forests . Quarters in tree hollows were also found here. Other catches are often found in bodies of water, but also in buildings. The species hunts insects in flight, and its diet in southern Africa includes beetles , butterflies and two-winged birds . The scales at the bottom of the males' crested hair are heavily modified and appear to be important for the release of pheromones for mating or for defense of territory.
Etymology & Research History
The holotype was collected by James Paul Chapin and Herbert Lang during a Congo expedition of the American Museum of Natural History in 1912 near Faradje in what is now the Democratic Republic of the Congo. In 1917 the first description was made by Joel Asaph Allen , he referred the species within the genus of the cantilever bats to the subgenus Lophomops created by him . The specific epithon chapini honors James Paul Chapin, who discovered the species.
Danger
The IUCN has classified the species as not endangered (“least concern”) due to its large distribution area and the presumably large population size.
