81. Lamotte’s Roundleaf Bat

Hipposideros lamottei


Lamotte’s roundleaf bat is characterised by an elaborately modified nose and muzzle which form leaf-like projections that are thought to help focus echolocation signals emitted through the nose.

The many and various modifications of the nose leaf are thought to be adaptations to specific modes and frequencies of nasal echolocation. They are from the roundleaf bat genus Hipposideros, considered one of the most diverse genera of bats with more than 70 species. The family they belong to, Hipposideridae, is a family of Old World leaf-nosed bats, which are more closely related to flying foxes (Megachiroptera) than to other microbats (Microchiroptera). Very little is currently known about the life history of this rare and threatened animal. It is known from a single locality, likely less than 100 km², close to Mount Nimba, and is also threatened by mining and deforestation.

  • Order: Chiroptera
  • Family: Hipposideridae

Lamotte’s roundleaf bat is known only from Mount Nimba in the border area of Guinea, Liberia and Côte d’Ivoire. On Mount Nimba it has been recorded from the localities of Grotte de Blandé and Pierré Richaud in Guinea. It has been recorded between 500 and 1,400 m above sea level.

Habitat and Ecology

Little is known about the habitat preference, or ecology of this species. It has been recorded with certainty from two habitats, one is lowland tropical moist forest, and a second in Afromontane savanna. It has also been collected roosting in a natural cave, and a small abandoned mining tunnel. Hipposiderids are generally insectivorous, with many capturing insects in flight and returning to a roost to eat captured prey.
