It is threatened by habitat loss through logging and other human activities.
Its forearm length is 40.2–42 mm (1.58–1.65 in).Its fur is brown or reddish brown.
As of 2016, it is evaluated as a data deficient species by the IUCN.It meets the criteria for this designation because its population size is unknown; its exact geographic range is unclear; and the threats to this species are not defined.Habitat destruction, however, is a likely threat.
