Taxonomy

Hills' horseshoe bat was first described as a new subspecies of Geoffroy's horseshoe bat with a trinomen of Rhinolophus clivosus hillorum in 1989. The holotype had been collected near Voinjama, Liberia. It was first recognized as a full species in 2002.[2] The eponyms for the species name "hillorum" were the unrelated mammalogists John Eric Hill and John Edwards Hill.[3]

Description

Hills' horseshoe bat has a forearm length of 52–57 mm (2.0–2.2 in), and individuals weigh 16.5–25 g (0.58–0.88 oz). It has a dental formula of 1.1.1.32.1.2.3 for a total of 28 teeth.[2]

Range and habitat

Hills' horseshoe bat is found in Western and Central Africa, where it has been confirmed in Cameroon, Guinea, Liberia, Nigeria. Its presence is possible yet unconfirmed in Uganda as of 2010.[1]

Conservation

As of 2010, it is evaluated as a near-threatened species by the IUCN. It meets the criteria for this classification because it is experiencing habitat destruction. Its extent of occurrence is likely less than 20,000 km2 (7,700 sq mi), and is close to qualifying for the more serious designation of "vulnerable". It likely has a small population size which is also declining. Specific threats this species faces include mining, quarrying, deforestation, and harvesting for bushmeat.[1]

gollark: Great, tell me when you're finished.
gollark: Say I want to have "edit distance from previous revision" in my revision list (which looks like this) for every row.
gollark: Plus more flaky logic to handle the difference in diffing (coming eventually™).
gollark: Well, yes, that particular one (edit distance) would be, except I would need to have some flaky logic to recalculate it if the current version in the `pages` table is shown with revisions.
gollark: However, if I wanted to add a field like "edit reason" to revisions, it would need to have an entry in pages AND revisions.
