The naked-rumped pouched bat (Saccolaimus saccolaimus), also known as the pouched tomb bat, is a species of sac-winged bat in the family Emballonuridae.
Described in 1838 by Coenraad Temminck. the author assigned the species to a new genus. The type location is in Indonesia. [2]
The uncertain diversity of related populations is represented by five subspecies,
The form nudicluniatus described by De Vis in 1905, [3] a population found in Queensland, was formerly recognised as Saccolaimus nudicluniatus .[ citation needed ]
The head and body length of naked-rumped pouched bats is 8–9 centimetres (3.1–3.5 in). The forearm measures an average of 7 centimetres (2.8 in) and the wingspan 45 centimetres (18 in). It has dark-reddish brown or blackish-brown upper parts which are irregularly marked with white patches. [4] [5] Their underparts are usually white, but in one colour phase it can be dark brown. [4] [5] They have no wing pouch or in other words, a poorly developed radio-metacarpal pouch. [4] They have a distinct glandular pouch on the throat. [4] [5] The ear is short and broadly rounded with ribbing on the interior of the pinna with a short tragus which has a semicircular margin. [4] It has long and narrow wings with black skin and translucent whitish portions. [4] It is the largest species with the whitest wings. [5]
The bat is found in India and Sri Lanka through South-East Asia to Borneo, Sumatra, Java and Timor, New Guinea, North-East Queensland (Australia), and Guadalcanal. [6] The species seems to no longer be present in Australia. [7] Bat-detector observations suggest that the species is very common in western Java, whereas further in the east (e.g. Bali) it is less common and its relative Taphozous melanopogon dominates in dry and coastal areas.
This medium-sized bat roosts in hollow trees and rock crevices and sometimes houses in colonies varying from a few individuals to a few hundred. [5] Roosting bats maintain individual spacing. They are alert at the roost and scurry all over the roost substrate if disturbed. [4] Echolocation clicks produced by this bat in flight are audible. females give birth to a single young per litter. [4] Bat-detector observations have revealed this species to be common in cities, villages, above rice fields, other (wet) cultivated areas and forest edges and has been heard up to 2000m in mountainous areas. This species is not commonly heard hunting over continuous forest. It is one of the earliest species to emerge and can often be seen hunting together with swiftlets about 15–40 metres above the ground, estimated from frequent visual observations. The build of this species suggests it to be an open-air forager. Individuals are usually seen hunting in wide circles over several hundred of metres. They have been seen feeding on termite swarms when available.
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 northern cave bat is a vespertilionid bat that occurs in most of Australia.
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.
Saccolaimus is a genus of the family Emballonuridae, small insectivorous bats with distinctive sheathtails and pouches at the wrist.
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.
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.
The common sheathtail bat, is a bat in the family Emballonuridae, occurring in northern Australia.
Hildegarde's tomb bat is a species of sac-winged bat in the family Emballonuridae. It is found near the coast in Kenya and Tanzania where it feeds in tropical dry forests and roosts in caves. It is a diurnal species and the International Union for Conservation of Nature has assessed its conservation status as "endangered". The specific name hildegardeae was given in honour of anthropologist Hildegarde Beatrice Hinde.
Hill's sheath-tailed bat is a bat of the family Emballonuridae. They are found in the deserts of central Australia.
The Arnhem sheath-tailed bat, species is an emballonurid bat found at the Top End of Australia. The species is also referred to as the white-striped sheathtail for the distinguishing marks at the flank, a feature observable beneath the wing when the animal is in flight. Records of the species are rare.
The Mauritian tomb bat is a species of sac-winged bat in the family Emballonuridae that is found in central and southern Africa and Madagascar. It was discovered in 1818 by Étienne Geoffroy Saint-Hilaire, and is characterized by an all-white ventral surface, grizzled dorsal coloration, and conical face. It has exceptionally good eyesight, a trait which is common in old world bats and enables it to find roosting locations. It has adapted itself to a wide range of habitats including subarid scrub to semi-tropical savanna and can be found throughout much of Africa south of the Sahara, including many of the surrounding islands. They often seek out refuge in cool dry areas. Mauritian tomb bats help control pest populations, including insects that carry human diseases. These bats tend to be nocturnal hunters and their normal prey consists of moths, butterflies, and termites. Not prone to large-scale roosting, T. mauritianus is most often spotted on the sides of buildings or on the trunks of trees in groups of around five individuals. They breed on average once or twice a year and rear usually one pup, though twins are occasionally reported. They usually deposit their hungry offspring in areas where they can feed ferociously, most often in berry bushes. This species is listed as least concern on the IUCN Red List due their wide distribution and stable population.
The naked-rumped tomb bat is a species of sac-winged bat in the family Emballonuridae. Found in northern Africa, the Middle East, and southeastern Asia, its natural habitats are dry savanna, subtropical or tropical dry shrubland and forests, caves, and arid areas.
The Egyptian tomb bat is a species of sac-winged bat in the family Emballonuridae. It is a medium- to large-sized microbat with a mass of approximately 30 g (1.1 oz). It is an aerial insectivore, foraging in open space. Based on individuals captured in Ethiopia, it is thought to feed predominantly on Lepidoptera, but is also known to feed on Isoptera, Coleoptera and Orthoptera.
Troughton's sheath-tailed bat is a species of sheathtail bat in the family Emballonuridae, found only in Australia.
