Incan little mastiff bat

The Incan little mastiff bat, Mormopterus phrudus, is a free-tailed bat in the family Molossidae, placed in the subgenus Micronomus, and is endemic to Peru, where it is known from a single site at Machu Picchu. Edmund Heller collected the type in 1915, but Charles Handley did not describe it until 1956, naming it phrudus, Greek for gone or disappeared, for the Lost City. With Kalinowski's mastiff bat it is one of only two New World Mormopterus species. It is dark brown, with a head and body length of 50 millimetres, thin rounded ears, wrinkled lips and a gular gland in males. It has been seen roosting in caves near 3,000 metres and occurs between 1,800 and 3,000 metres in subtropical forest, over an area of only about 20 square kilometres. The IUCN lists it as Vulnerable and Peru as Critically Endangered, though it lives in a protected area.
