“Habite Java.”

Nyctenis javanica belongs to the javanica group. Monotypic.

Distribution. Known only from Java, Kangean Is, and Nusa Penida I. Also mentioned in West Timor, but these records are very doubtful.

Descriptive notes. Forearm 43-50 mm, no other specific measurements available. The Javan Slit-faced Bat is small, with short rounded wings. 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. Wing membranes are dark brown. There are no obvious sexual differences in pelage.

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.
