The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels.
Cheiromeles is a genus of bats in the family Molossidae, the free-tailed bats. The genus was erected and described by Thomas Horsfield, who developed the name from the Greek word cheir ("hand"), a reference to the hand-like hindfoot, which has a toe that flexes like an opposable thumb. These bats have mostly hairless bodies and fold their wings into pouches of skin along their bodies when at rest. These are among the largest insectivorous bats, weighing up to 135 grams.
Emballonuridae is a family of microbats, many of which are referred to as sac-winged or sheath-tailed bats. They are widely distributed in tropical and subtropical regions around the world. The earliest fossil records are from the Eocene.
The dwarf dog-faced bat is a species of free-tailed bat from South America. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Paraguay and Uruguay, typically at lower elevations. It is one of two species in the genus Molossops, the other being the rufous dog-faced bat. Three subspecies are often recognized, though mammalogist Judith Eger considers it monotypic with no subspecies. It is a small free-tailed bat, with a forearm length of 28.9–32.5 mm (1.14–1.28 in) and a weight of 5–8 g (0.18–0.28 oz); males are larger than females. It is brown, with paler belly fur and darker back fur. Its wings are unusual for a free-tailed bat, with exceptionally broad wingtips. Additionally, it has low wing loading, meaning that it has a large wing surface area relative to its body weight. Therefore, it flies more similarly to a vesper bat than to other species in its own family. As it forages at night for its insect prey, including moths, beetles, and others, it uses two kinds of frequency-modulated echolocation calls: one type is to navigate in open areas and to search for prey, while the other type is used for navigating in cluttered areas or while approaching a prey item.
The black mastiff bat is a bat species. It ranges from the northern region of South America, most of Central America and parts of southern Mexico.
The Para dog-faced bat, also called the brown dog-faced bat, is a South American bat species of the family Molossidae. It is found in Panama, Colombia, Ecuador, Peru, Venezuela, Guyana, Suriname, French Guiana, Brazil, and northern Argentina.
Eptesicus is a genus of bats, commonly called house bats or serotine bats, in the family Vespertilionidae. The genus name is likely derived from the Greek words ptetikos 'able to fly' or petomai 'house flier', although this is not certain.
Anoura is a genus of leaf-nosed bats from Central and South America. Anoura members lack or have a short tail, and are nectarivorous bats of small to medium size among the Phyllostomidae.
Taphozous is a genus of the family Emballonuridae. The wide distribution of the genus includes several regions of Australia, Indonesia, Papua New Guinea and Africa. Taphozous comes from the Greek τάφος, meaning "a tomb". The common names for species include variants on sac-winged, sheathtail, or tomb bats.
Molossops is a genus of bat in the family Molossidae. The four member species are found in nearly every country of South America, with the dwarf dog-faced bat being found in the most countries. It contains only two species:
Glossophaginae is a subfamily of leaf-nosed bats.
Nyctimene is a genus of bats in the Pteropodidae family. Commonly known as tube-nosed fruit bats, they are found in the central Philippines, eastern Indonesia, Papua New Guinea and the north-east coast of Australia.
The Aztec mastiff bat is a species of bat in the family Molossidae. It is insectivorous.
Austronomus, known as Australasian free-tailed bats, is a molossid genus of microchiropterans. The two recognised species are the white-striped Austronomus australis, found in a wide distribution range across Australia, and the New Guinea species Austronomus kuboriensis.
Molossus alvarezi, or Alvarez's mastiff bat, is a species of bat in the family Molossidae, native to the Yucatán Peninsula. It lives within a relative homogenous environment within perennial forests, low forests, and a band of xeric vegetation.
