Taxonomy and etymology

It was described as a new species in 1975 by David Harrison. The

Description

Its fur is

Its ears are large and conjoined via the interaural membrane. The interaural membrane has a deep, backwards-facing pocket containing an interaural crest with hairs approximately in length. The bat is likely able to evert this pocket to display the crest. It is unique in its family due to the presence of large, paired "nasal inflations" similar to those found in the

Biology and ecology

As only one individual—a male—has been documented, little is known about its biology and ecology. Based on other members of its genus, it is hypothesized that Gallagher's free-tailed bat forages for insects at relatively high altitudes with a fast but not maneuverable flight.

Range and habitat

The holotype was collected in the Scierie Forest, approximately southwest of Kindu, Democratic Republic of the Congo. It was captured in a

forest. The forest where the holotype was collected has been heavily logged. It is nocturnal, possibly roosting in hollow trees, rock crevices, or caves during the day.

Conservation

It is currently evaluated as

by the IUCN, meaning that not enough information is available to assess its conservation needs. From 1996–2008, it was considered critically endangered, the most dire assessment category.
