Hill's roundleaf bat

Hill's roundleaf bat (Hipposideros edwardshilli) is a species of bat in the family Hipposideridae endemic to Papua New Guinea.

Taxonomy
Hill's roundleaf bat was described as a new species in 1993 by Tim Flannery and Donald Colgan. The holotype had been collected in the Bewani Mountains near Imonda Station in 1990 by P. German and L. Seri. The eponym for the species name "edwardshilli" was British mammalogist John Edwards Hill, "in recognition of his outstanding contributions to bat taxonomy".

Description
Individuals have a forearm length of 49.6-51 mm and a very short tail length of 11.1-15 mm. It differs from all other Hipposideros species in its two club-like projections on its nose-leaf.

Range and habitat
Hill's roundleaf bat is endemic to Papua New Guinea in Oceania. It has been documented at a narrow range of elevations from 200-300 m above sea level.

Conservation
As of 2021, it is evaluated as a vulnerable species by the IUCN. It meets the criteria for this designation because it has a potentially limited habitat for roosting. Its area of occupancy is possibly less than 2000 km2. Habitat loss is ongoing through deforestation. It has not been documented since its description in 1993.
