[1] It commonly roosts in human-made structures, sometimes in colonies with other free-tailed bat species.

[2] The bat is sexually dimorphic, with males larger than females.

[4] In his description of the species (in Latin), Peters wrote that it had "fovea jugulari magna", or a large suprasternal notch.

Its fur is soft and dense, with its back grayish-brown to charcoal in color, and its belly paler.

[5] It is endemic to Madagascar, where it has been documented from 0–1,200 m (0–3,937 ft) above sea level.
