The Arnhem leaf-nosed bat has one of the most limited distributions of any Australian bat taxon. Currently, it is known to occur only in the Kakadu escarpment and adjoining western edge of the Arnhem Land plateau (Deaf Adder Gorge and upper South Alligator River area), although large areas in the central and eastern parts of the Arnhem plateau remain unsurveyed. In 1978, a population containing 15 individuals was discovered in a cave at Tolmer Falls, Litchfield National Park. However, no bats have been recorded in this cave or the surrounding vicinity since 1983, despite several targeted searches in the area.
