Mouse-tailed bats are a group of insectivorous microbats of the family Rhinopomatidae with only three to six species, all contained in the single genus Rhinopoma. [2] They are found in the Old World, from North Africa to Thailand and Sumatra, in arid and semiarid regions, roosting in caves, houses and even the Egyptian pyramids. They are relatively small, with a body length of just 5 to 6 cm. [3] They weigh between 6 and 14 g.
Rhinopomatidae are small bats with very slim limbs and a long, thin, hairless tail, which is nearly the same length as the rest of the body and not connected to the patagium. Their sand-colored coat is soft and short. The snout has a small and simple nose leaf with valvular nostrils. Their big ears have a well-developed tragus and are connected to their big, black eyes by a band of skin across the forehead. [4] There is a fat repository located near the caudal peduncle and the hind legs. Of all the bats, Rhinopomatidae have the shortest fingers relative to their forearm-length. They have a head-body length of 50 to 90 mm, forearm-length of 45 to 75 mm, a tail-length of 40 to 80 mm and a body weight of 6 to 14 grams.
Rhinopomatidae live in deserts and semi-arid climates in North Africa and South Asia, from Morocco and Senegal to South Sudan, the Middle East and India to Myanmar, Thailand, and North-Sumatra. They also come to agricultural areas and disturbed areas. They are adaptable and live along walls with low humidity and high temperatures. They also use crevices, rock walls, houses, tombs (including the Egyptian Pyramids, where they have been coming for more than three-thousand years), tunnels and caves as shelters. Animals from the more northern parts of South-Asia travel to winter colonies, where they become torpid, although they do not truly hibernate. In very dry periods during a food shortage they estivate, where they live on their fat stores.
Rhinopomatidae live in colonies of thousands, where they gather in small, scattered groups. Mixed groups are common but groups with only males or females also occur. They live in roosts of a thousand or more members, and have one or two young per year. [4] They have poor flight endurance and fast fliers quickly become exhausted. They can also quickly run on the ground. They hunt small insects including beetles that have flight altitudes of five to ten meters.
This family is closely related to Kitti's hog-nosed bat, complementing the Rhinopomatidae in the superfamily Rhinopomatoidea. They are also closely related to horseshoe bats, Old World leaf-nosed bats and pteropodids, the other members of the suborder Yinpterochiroptera. There are four species that appear in the drier areas of North Africa and in southern Asia. There are two known fossil genera, Corbarhina from the Miocene of France [5] and Qarunycteris from the Eocene of Egypt. [6]
Family Rhinopomatidae
Kitti's hog-nosed bat, also known as the bumblebee bat, is a near-threatened species of bat and the only extant member of the family Craseonycteridae. It occurs in western Thailand and southeast Myanmar, where it occupies limestone caves along rivers.
Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania.
Megadermatidae, or false vampire bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a wide membrane between the hind legs, or uropatagium, but no tail. Many species are a drab brown in color, but some are white, bluish-grey or even olive-green, helping to camouflage them against their preferred roosting environments. They are primarily insectivorous, but will also eat a wide range of small vertebrates.
The cinnamon dog-faced bat, is a South American bat species of the family Molossidae. It is found in northern and central South America.
Botta's serotine is a species of vesper bat, one of 25 in the genus Eptesicus. It is found in rocky areas and temperate desert.
The Ussuri tube-nosed bat is a species of vesper bat in the family Vespertilionidae. It is threatened by habitat loss. It is the only species of bat that hibernates in snowbanks.
The yellow-bellied sheath-tailed bat, also known as the yellow-bellied sheathtail or yellow-bellied pouched bat, is a microbat species of the family Emballonuridae found extensively in Australia and less commonly in parts of Papua New Guinea.
The Kolar leaf-nosed bat, or leafletted leaf-nosed bat is a species of bat in the family Hipposideridae. It is endemic to India. Its natural habitats are subtropical or tropical dry forests and caves. It is found in only one cave in India, and its population is less than 200 individuals.
The lesser mouse-tailed bat is a species of microbat in the family Rhinopomatidae. Also referred to as Hardwicke's lesser mouse-tailed bat and long-tailed bat, it is named after Major General Thomas Hardwicke (1755–1835), an English soldier and naturalist who served many years in India. It is found in North Africa, some parts of central and eastern Africa, West Asia and east to the Indian subcontinent.
The greater mouse-tailed bat is a species of bat in the Rhinopomatidae family.
The small mouse-tailed bat is a species of bat in the Rhinopomatidae family. It is found in Afghanistan, Iran, Oman, and possibly Ethiopia, ranging from the Sistan Basin in Iran well into the Helmand River basin of south-western Afghanistan.
The Egyptian free-tailed bat, also known as Egyptian guano bat or Egyptian nyctinome, is a species of bat in the family Molossidae.
Lamotte's roundleaf bat is a species of bat found only at Mount Nimba on the border of Côte d'Ivoire, Guinea and Liberia. It is critically endangered.
The Hipposideridae are a family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family. Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera.
Triaenops menamena is a bat in the genus Triaenops found on Madagascar, mainly in the drier regions. It was known as Triaenops rufus until 2009, when it was discovered that that name had been incorrectly applied to the species. Triaenops rufus is a synonym of Triaenops persicus, a Middle Eastern species closely related to T. menamena— the Malagasy species had previously been placed as a subspecies of T. persicus by some authors. Triaenops menamena is mostly found in forests, but also occurs in other habitats. It often roosts in large colonies and eats insects such as butterflies and moths. Because of its wide range, common occurrence, and tolerance of habitat degradation, it is not considered to be threatened.
The Japanese short-tailed bat is a species of bat belonging to the family Vespertilionidae. It is endemic to Japan where it is found at the base of the northern Japanese Alps, the Chichibu Mountains and Oze National Park, mostly at altitudes higher than 700 m.
The Yemeni mouse-tailed bat is an endangered species of bat found in Yemen. It is only known from one roost, and its population is estimated at 150 individuals.
Harrison's large-eared giant mastiff bat is a species of bat found in Northeast Africa and the Arabian Peninsula. It was described as a new species in 2015. The IUCN evaluates it as a vulnerable species.
The Egyptian mouse-tailed bat is a species of mouse-tailed bat found in North Africa and the Middle East.
The Dhofar pipistrelle is a species of vesper bat in the genus Pipistrellus. It is found in Southern Arabia, including Oman and Yemen.
