The eastern bent-wing bat (Miniopterus fuliginosus) is a species of vesper bat in the family Miniopteridae. It is found in South Asia, Far-east Asia, the east Caucasus Mountains and also in Southeast Asian regions.
They exhibit long and narrow wings, high wingspans and low wing loadings, which enable quick and long flights. Head and body length is 10 to 11 centimetres (3.9 to 4.3 in) and the forearms are 4 to 5 centimetres (1.6 to 2.0 in) long with a wingspan of 30 to 31 centimetres (12 to 12 in). [1]
Color varies from reddish brown to dark blackish brown above, with the underparts being lighter. The wing membrane is blackish brown. Fur is dense and soft, long above and short below. The ears are small and the cheeks are hairless below the eyes.
Zhang Jiang Lu et al. 2018 reported that echolocation frequencies were very similar among Eastern bent-wing bat colonies and variation in echolocation calls were likely due to variations in background noise instead of genetic drift. [2]
This species was once considered a subspecies of the common bent-wing bat, but now it has been accepted that the eastern bent-winged bat and Australasian bent-winged bat are two separate species. [3]
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.
Icaronycteris is an extinct genus of microchiropteran (echolocating) bat that lived in the early Eocene, approximately 52.2 million years ago, making it the earliest bat genus known from complete skeletons, and the earliest known bat from North America. Multiple exceptionally preserved specimens, among the best preserved bat fossils, are known from the Green River Formation of North America. The best known species is I. index. Fragmentary material from France has also been tentatively placed within Icaronycteris as the second species I. menui. I. sigei is based on well-preserved fragments of dentaries and lower teeth found in Western India. In 2023, the species I. gunnelli also from the Green River Formation was distinguished from I. index, and I. menui and I. sigei were proposed to be removed from the genus due to them not being closely related.
The pale spear-nosed bat is a species of phyllostomid bat from South and Central America.
Hodgson's bat, also called the copper-winged bat or black-and-orange myotis, is a species of vesper bat in the genus Myotis, the mouse-eared bats. Favouring mountain forests, it is found throughout Central, Southeast, and East Asia, from Afghanistan to Taiwan. It is about 5 centimetres (2.0 in) long and is distinguished from most other species of bat in this range by its yellowish colouration.
The lesser bamboo bat or lesser flat-headed bat is one of the smallest species of vesper bat, and is native to Southeast Asia.
The variegated butterfly bat is a species of vesper bat. It is sometimes also called the leaf-winged bat, or simply the butterfly bat. It is not currently endangered, but may be threatened by habitat loss in some parts of its range.
The common bent-wing bat, also known as the Schreibers's long-fingered bat or Schreibers's bat, is a species of insectivorous bat. They appear to have dispersed from a subtropical origin and distributed throughout the southern Palearctic, Ethiopic, Oriental, and Australian regions. In Europe, it is present in the southern half on the continent from Iberia to the Caucasus, with the largest populations found in the warmer Mediterranean area. The common and scientific names honor Carl Franz Anton Ritter von Schreibers.
The western small-footed bat, also known as the western small-footed myotis, is a species of vesper bat native to North America.
Ansorge's free-tailed bat is a species of bat in the family Molossidae native to sub-Saharan Africa. It is named for W.J. Ansorge, who collected the first formally described specimen.
The little free-tailed bat is a species of the genus Mops in the family Molossidae. It is widely distributed across Africa and islands around the continent.
The lesser woolly horseshoe bat, also called Beddome's horseshoe bat, is a species of bat in the family Rhinolophidae. It is found in India and Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests, caves, and urban areas.
The Cape horseshoe bat is a species of bat in the family Rhinolophidae. It is endemic to South Africa, and is potentially threatened by habitat loss and disturbance of its roosting sites, although it is present in large enough numbers to be considered of least concern by the IUCN.
Miniopterus, known as the bent-winged or long winged bats, is the sole genus of the family Miniopteridae. They are small flying insectivorous mammals, micro-bats of the order Chiroptera, with wings over twice the length of the body. The genus had been placed in its own subfamily among the vespertilionid bats, as Miniopterinae, but is now classified as its own family.
Bats are flying mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is 29–34 millimetres in length, 150 mm (6 in) across the wings and 2–2.6 g in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox reaching a weight of 1.6 kg and having a wingspan of 1.7 m.
Miniopterus griveaudi is a bat in the genus Miniopterus found on Grande Comore and Anjouan in the Comoros and in northern and western Madagascar. First described in 1959 from Grande Comore as a subspecies of the mainland African M. minor, it was later placed with the Malagasy M. manavi. However, morphological and molecular studies published in 2008 and 2009 indicated that M. manavi as then defined contained five distinct, unrelated species, and M. griveaudi was redefined as a species occurring on both Madagascar and the Comoros.
Griffith's long-fingered bat is a bat in the genus Miniopterus which occurs in southern Madagascar. M. griffithsi was previously a part of the largest family of bats, the Vespertilionidae, which consist of five subfamilies. The bat family Miniopteridae is widely distributed, ranging from the majority of sub-Saharan Africa to north Africa and Eurasia, as well as southern and southeastern Asia and Australia. Typical features of these bats include elongated third fingers, long narrow wings giving them a pointed shape when in flight, and a bent shape when folded, adding to the common name of bent-wing bats. M. griffithsi is similar to its sister species Miniopterus gleni, which lives north of the Onilahy River, while M. giffithsi lives south of it. Researchers first discovered that M. griffithsi was separate from M. gleni based on phylogeographic studies of the latter.
Bats are the only mammal capable of true flight. Bats use flight for capturing prey, breeding, avoiding predators, and long-distance migration. Bat wing morphology is often highly specialized to the needs of the species.
The southern bent-wing bat is one of two subspecies of the Australasian bent-wing bat. Its population size has declined rapidly since the 1950s, and it is classified as critically endangered by the Australian government.
The Javanese long-fingered bat is a species of bat from the Miniopterus genus native to Indonesia. A common misconception was that Miniopterus blepotis belonged to the M. schreibersii subspecies. M. blepotis was recognized as a distinct species after the Schreibersii complex was divided. This is backed up by New Guinean mtDNA sequence data that is ascribed to M. blepotis. Whether it is a complex made up of multiple species is unknown.
