Taxonomy
Described in 1838 by Coenraad Temminck. the author assigned the species to a new genus. The type location is in Indonesia. The uncertain diversity of related populations is represented by five subspecies, * species ''Saccolaimus saccolaimus'' Temminck, 1838. ** subspecies '' Saccolaimus saccolaimus saccolaimus'' ** subspecies '' Saccolaimus saccolaimus affinis'' ** subspecies '' Saccolaimus saccolaimus crassus'' ** subspecies '' Saccolaimus saccolaimus nudicluniatus'' De Vis, 1905. ** subspecies '' Saccolaimus saccolaimus pluto'' The form ''nudicluniatus'' described by De Vis in 1905, a population found in Queensland, was formerly recognised as ''Description
The head and body length of naked-rumped pouched bats is . The forearm measures an average of and the wingspan . It has dark-reddish brown or blackish-brown upper parts which are irregularly marked with white patches. Their underparts are usually white, but in one colour phase it can be dark brown. They have no wing pouch or in other words, a poorly developed radio-metacarpal pouch. They have a distinct glandular pouch on the throat. The ear is short and broadly rounded with ribbing on the interior of the pinna with a short tragus which has a semicircular margin. It has long and narrow wings with black skin and translucent whitish portions. It is the largest species with the whitest wings.Distribution
The bat is found in India andBiology and ecology
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. Roosting bats maintain individual spacing. They are alert at the roost and scurry all over the roost substrate if disturbed. Echolocation clicks produced by this bat in flight are audible. females give birth to a single young per litter. 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.References
