Longitudinal cleft runs along top of muzzle, covering noseleaves. Fur is long and fluffy, pale reddish brown to grayish brown dorsally, and slightly lighter ventrally. Ears are very long.

Status and Conservation. Classified as Vulnerable on The IUCN Red List. Small global distribution of the Javan Slitfaced Bat and its dependence on lowland rainforest make it of particular conservation concern. It is currently the most threatened species of Nycteridae . Practically nothing is known about its ecology, impeding implementation of effective conservation action.
