The Incan little mastiff bat (Mormopterus phrudus) is a species of bat in the family Molossidae, the free-tailed bats. It belongs to the subgenus Micronomus.

Taxonomy and etymology

It was described as a new species by American zoologist Charles O. Handley. Although the holotype had been collected in 1915 by Edmund Heller, it was not scientifically described until 1956.^[2] Its species name "phrudus" comes from Ancient Greek "phroudos," meaning "gone" or "disappeared." Handley chose this name "with allusion to their type locality, the 'Lost City' of Machu Picchu..."^[2] Along with Kalinowski's mastiff bat, it is one of only two species of Mormopterus in the New World.^[3]

Description

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]

Conservation

This bat is endemic to Peru, where it is known only from one location; its type locality is Machu Picchu. It is considered a vulnerable species by the International Union for Conservation of Nature (IUCN) and a critically endangered species by the nation of Peru; though it is rare, it lives in a protected area.^[1]
