The Emballonurini are a genus group from the bat family of the smooth-nosed cantilever tails (Emballonuridae). They include around 12 species in the four genera Coleura , Emballonura , Mosia and Paremballonura .
These bats are in Africa south of the Sahara , Southeast Asia , New Guinea and numerous islands in the western and southern Pacific common.
description
Emballonurini are very small bats, they reach a head body length of three to seven centimeters and a weight of 2.5 to 10 grams. Its snout is elongated and slightly curved upwards, there is no nasal blade. The short tail protrudes a bit from the tail membrane. Their fur is brown on the upper side, the underside is lighter. Unlike most other types of smooth-nosed cantons, they do not have glands on the top of their wings.
Way of life
Emballonurini are primarily forest dwellers, although they can also be found in other habitats, often near humans. In addition to caves and crevices, hollow trees and overhanging earth walls serve as resting places. One species, Coleura afra , is known to live in large colonies (up to 50,000 animals), while other species form smaller groups (20 to 150 specimens). The diet of these animals consists primarily of insects, and occasionally they also eat fruit.
Genera and species
- The genus Coleura includes three species:
- Coleura afra occurs in large parts of Africa south of the Sahara and in the southwest of the Arabian Peninsula and lives in large colonies of often 50,000 animals. These colonies are divided into subgroups of around 20 animals, which consist of a male, a harem of several females and their offspring.
- Coleura seychellensis isendemicto the Seychelles , where it wasthe only mammalalongside the Seychelles fruit bat until the arrival of humans. According to the IUCN , thespecies is one ofthe hundred most critically endangered animal species; the population size is estimated at only 50 to 100 animals.
- Coleura kibomalandy was originally a synonym of Coleura afra and occurs in Madagascar.
- The genus Emballonura comprises seven species that live on Madagascar , Southeast Asia ( Malay Peninsula and Indonesia ), New Guinea and several islands in the Pacific (including Micronesia , Fiji , Samoa and Tonga ). It differs from Coleura mainly in the number of teeth. E. semicaudata , which lives on some Pacific islands, is considered threatened and three other species are endangered.
- The genus Mosia includes only one species, Mosia nigrescens , which is common in the Moluccas , New Guinea, and the Solomon Islands . With a length of 32 to 41 millimeters and a weight of two to four grams, it is one of the smallest bats ever.
- The genus Paremballonura , which was only introduced in 2012, includes two Malagasy species that originally belonged to Coleura .
