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.

Taxonomy

The genus was erected in 1837 by Charles L. Bonaparte. In the first systematic revision of the genus, published in a monograph of Miniopterus in 1858 by Robert F. Tomes, the author reallocated specimens and described new taxa. [3] A new systematic arrangement was produced in an extensive study of poorly known chiropterans of the Indo-Austral region by James E. Hill in 1985, the greater resolution of the genus being determined by the British Museum of Natural History's acquisition of new series of specimens collected in Fiji, the New Hebrides and New Caledonia and the extensive collection made in New Guinea by ecologist Ben Gaskell on "Operation Drake". [4]

Recognised as a very widely dispersed group with distinct morphology, biology and genetic characters, the number of species and systematic arrangements varied between still contradictory treatments. The genus was nested within Vespertilionidae as Miniopterinae, one of five subfamilies, with doubts remaining on the relationships to sister groups. The position of the minopterines was determined as showing a phylogenetic relationship to either the vespertilionids or the molossids, these assumptions were compared and analysed in study using large data sets derived from multiple genetic indicators and statistical analysis to determine the basal relationships within the order Chiroptera. The authors of this 2007 study found support for elevation to the rank of family—as Miniopteridae—and that the vespertilionids and Miniopterus species formed a clade that had diverged from the molossids (free-tailed bats) at a period around 54–43 million years ago and from other species 49–38 mya. [2]

Morphology

Bent-winged bats are typically small (total length c. 10 cm, wingspans 30–35 cm, mass less than 20 g), with broad, short muzzles. The cranium is bulbous and taller than the snout, a feature shared with woolly bats and mouse-eared bats. This combination of features was likely present in the common ancestor of the vesper bats. They have two tiny, vestigial premolars between the upper canines and first large premolar. Unlike other bats, they lack a tendon-locking mechanism in their toes.

The common name bent-winged bat refers to their most obvious feature, the group's ability to fold back an exceptionally long third finger when the wings are folded. This finger gives the bats long, narrow wings that allows them to move at high speed in open environments and in some species to migrate over a distance of hundreds of kilometres. [5] [2] The proportional length of the wing is around two and a half times that of the body and head. [6]

Research applications

In 2017, evidence of deltaretroviruses was found in the genome of the Miniopteridae. [7] Deltaretroviruses only affect mammals, and this was the first evidence that they affected bat species. [7] The presence of the deltaretrovirus in multiple Miniopterid species suggests that the virus was present in the family before speciation 20 million years ago. [7] The evolutionary history of deltaretroviruses is important because they cause leukemia in humans.

Classification

Family Miniopteridae

Range

Bent-winged bats occur in southern Europe, across Africa and Madagascar, throughout Asia, and in Australia, Vanuatu and New Caledonia. One species, the common bent-wing bat, inhabits the whole of this range. [5] The group rapidly colonized much of this area in the last 15,000 years.

Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".

The Manavi long-fingered bat is a bat in the genus Miniopterus that occurs in east-central Madagascar. First described in 1906, this species was later included in the mainland African M. minor. A 1995 revision united populations of small Miniopterus from Madagascar and the Comoros as M. manavi, but molecular and morphological studies in 2008 and 2009 showed that this concept of M. manavi in fact included five different species. M. manavi itself was restricted to a few locations in the eastern Central Highlands and populations in the Comoros and northern and western Madagascar were allocated to different species.

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.

<span class="mw-page-title-main">Central Highlands (Madagascar)</span> Biogeographical region in Central Madagascar

The Central Highlands, Central High Plateau, or Hauts-Plateaux are a mountainous biogeographical region in central Madagascar. They include the contiguous part of the island's interior above 800 m (2,600 ft) altitude. The Central Highlands are separated from the Northern Highlands of the northern tip of Madagascar by a low-lying valley, the Mandritsara Window, which has apparently acted as a barrier to dispersal for species in the highlands, leading to species pairs such as Voalavo gymnocaudus and Voalavo antsahabensis in the Northern and Central Highlands. Species restricted to the Central Highlands include the bats Miniopterus manavi and Miniopterus sororculus; the rodents Brachyuromys betsileoensis and Voalavo antsahabensis; the tenrecs Hemicentetes nigriceps and Oryzorictes tetradactylus; and the lemur Cheirogaleus sibreei. Because of the continuous habitat of the Central Highlands, there is little local endemism, unlike the Northern Highlands.

The species has been found in dry, spiny, and gallery forest, as well as more open habitats, in southwestern Madagascar.

Miniopterus zapfei is a fossil bat in the genus Miniopterus from the middle Miocene of France. First described in 2002, it is known only from the site of La Grive M, where it occurs with another fossil Miniopterus species, the smaller and more common Miniopterus fossilis. M. zapfei is known from five mandibles and an isolated fourth upper premolar (P4). The fourth lower premolar is more slender than in M. fossilis and the cingulum shelf surrounding the P4 is less well-developed than in living Miniopterus. The length of the first lower molar is 1.57 to 1.60 mm.

<span class="mw-page-title-main">Griffith's long-fingered bat</span> Species of bat

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.

The sandy long-fingered bat, also known as the sandy bent-winged bat, is a species of bat from the genus Miniopterus that is endemic to the Arabian Peninsula and East Africa. The species was initially described as a subspecies of either M. schreibersii or M. natalensis. Recent genetic research has revealed that specimens from the Arabian Peninsula and Ethiopia, which were tentatively ascribed to the genus, are significantly distinct from M. schreibersii and M. natalensis. A genetic analysis of type locality material is still needed before taxonomy can be resolved.

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.
