The snub-eared bat ( Tomopeas ravus ) is a species of bat endemic to Peru from the family of bulldog bats (Molossidae), which is particularly notable for its controversial systematic position.

description

The short-eared bat reaches a head body length of 73 to 85 millimeters. The tail becomes 34 to 45 millimeters long and, in contrast to the rest of the bulldog bats, does not protrude from the uropatagium (the tail fly skin ). With a weight of 2 to 3.5 grams, it is one of the smallest bats at all. Their fur is light brown on the top and light gray on the underside; the face, ears and membranes are black.

Way of life

Little is known about the way of life of this bat species. The short-eared bat lives in the dry coastal regions of Peru up to an altitude of 2,300 meters. She is likely to use leaves from mesquite trees as well as crevices as resting places . Pups were sighted in August and September, suggesting that the females give birth to their young during the dry season. The range of the species is estimated to be less than 100 km². Due to the destruction of their habitat restricted by the spread of settlements and agriculture, as well as the destruction of neighborhoods, especially caves, the kind of which is IUCN as endangered ( endangered ) listed.

Systematics

The snub-eared bat combines features of the smooth-nosed bat (Vespertilionidae) - such as the structure of the tail - and of the bulldog bats (Molossidae) - such as the structure of the vertebrae . In the past it was assigned to the smooth-nosed bats, but more recent, genetic studies also see it as a member of the bulldog bats. There it forms its own subfamily, tomopeatine, and is the sister taxon of all other bulldog bats.
