The big-eared mastiff bat (Otomops papuensis) is a species of bat in the Molossidae family endemic to Papua New Guinea. It is only known from eleven specimens and it is not easy to survey. It forages in rainforest canopy and roosts in tree hollows. It is likely more widespread than currently known but additional research is needed.
The big-eared mastiff bat was described as a new species in 1948 by American mammalogist Barbara Lawrence. The holotype had been collected at Vailala River of Papua New Guinea, approximately 24 km (15 mi) to the west of the city of Kerema. [2] The holotype was collected in 1862. [3]
Overall, its fur is a rich, reddish brown. Individuals hair are darker at the tips and paler at the bases. The underside of its body is lighter in color than its backside, with its throat particularly pale. It has large, rounded ears that lack antitragi; the tragus is very small and scarcely visible. Like some other species of free-tailed bat, there is a connecting band of tissue (interaural membrane) between its ears. [2]
Unlike some closely related genera of free-tailed bat, its upper lip is not wrinkled. The measurements of the holotype were as follows: total length, 97 mm (3.8 in); tail, 30 mm (1.2 in); forearm, 49.2 mm (1.94 in); ear, 22.2 mm (0.87 in); hind foot, 10.6 mm (0.42 in). Overall, it is similar in appearance to the Wroughton's free-tailed bat. [2]
It is believed that this species forages for food in the rainforest canopy. It possibly roosts within tree hollows. [1]
As of 2020, is known from two sites in Papua New Guinea, where it has been found in Gulf Province and Oro Province. These two sites are at elevations between 0–300 m (0–984 ft) above sea level. [1]
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.
The velvety free-tailed bat or Pallas's mastiff bat, is a bat species in the family Molossidae.
The northern freetail bat is a species of bat found in Yapen, Seram Island, Western New Guinea and Northern Australia.
Beccari's free-tailed bat is a species of bat in the free-tailed bat family Molossidae found to Indonesia and Papua New Guinea. It can be found in several habitat types, including savanna, tropical moist forest, and fragmented and urban habitat. It roosts in trees, caves, and buildings in small colonies. This is a common species which is not considered to be threatened. The names Beccari's free-tailed bat or Beccari's mastiff bat once applied to populations in Australia.
Ozimops planiceps is a small bat in the family Molossidae, native to Australia and Indonesia.
The Incan little mastiff bat is a species of bat in the family Molossidae, the free-tailed bats. It belongs to the subgenus Micronomus.
The northern broad-nosed bat is a species of the vespertilionid family of microbats. It can be found in northern Australia, Timor-Leste, and Papua New Guinea.
The golden-tipped bat is a species of Microchiropteran in the family Vespertilionidae. It is found in Papua New Guinea and in Australia, especially scattered along the eastern part of Australia. The species is considered uncommon, and is listed as endangered in Australia.
The southern forest bat is a vesper bat found in Australia.
The Papuan sheath-tailed bat is a species of bat in the family Emballonuridae which occurs at the Cape York Peninsula and New Guinea. The poorly known species hunts in open forests for night flying insects.
Semon's leaf-nosed bat or Semon's roundleaf bat is a species of bat in the family Hipposideridae. It is found in Australia and Papua New Guinea.
The northern leaf-nosed bat is a micro-bat of the family Hipposideridae, known as "leaf-nosed" bats. The species is endemic to northern regions of Australia. They are highly manoeuvrable in flight, and use echolocation to forage for insect prey.
Otomops is a genus of bat in the family Molossidae. Molecular sequence data supports it as a monophyletic taxon, although not a number of other molossid genera.
The smaller horseshoe bat is a species of bat in the family Rhinolophidae. It is found in Australia and Papua New Guinea.
The white-striped free-tailed bat is a species of bat in the family Molossidae. Its echolocation calls are audible to humans, which is a characteristic found in only a few microbat species. The species was formerly classified as Tadarida australis.
Wroughton's free-tailed bat is a free-tailed bat formerly considered to be confined to the Western Ghats area of India, though it has also recently been discovered in northeast India and in a remote part of Cambodia. It is classified as a Data Deficient species as little is known about their habitat, ecology, or foraging range.
Gallagher's free-tailed bat is a free-tailed bat endemic to the Democratic Republic of the Congo. Only one individual has ever been documented.
The Madagascar free-tailed bat or Malagasy giant mastiff bat is a species of free-tailed bat formerly included as a subspecies of the large-eared free-tailed bat, but that was later considered to be a distinct, Malagasy species. The Madagascar free-tailed bat is endemic to northern, western, and southern Madagascar.
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.
