The Incan little mastiff bat (Mormopterus phrudus) is a species of bat in the family Molossidae, the free-tailed bats. It belongs to the subgenusMicronomus.
Its head and body length is 50 mm (2.0 in); its tail length is 29 mm (1.1 in); its forearm length is 34 mm (1.3 in).[2] Its fur is dark brown.[3] Its ears are thin, rounded, and not conjoined as in some other free-tailed bats. It has a small tragus with a pointed tip and an inconspicuous antitragus.
Its lips are slightly wrinkled. Males, at least, have a gular gland. Its dental formula is 1.1.2.32.1.2.3, for a total of 30 teeth.[2]
Biology and ecology
Little is known about the biology of the bat. It has been observed roosting in caves at an altitude of 3,000 m (9,800 ft). It may be a microendemic species.[1]
Range and habitat
It is only known for its very small occupancy area of 20 km2 (7.7 sq mi). It is documented at relatively high elevations, from 1,800–3,000 m (5,900–9,800 ft) above sea level.[1] It occurs in lowland subtropical forest.[3]
