Hipposideridae, Old World leaf-nosed bats, is one of eighteen families that make up the order Chiroptera, and consists of nine genera. The largest genus is Hipposideros (roundleaf bats), which consists of 76 species. The remaining genera are Asellia (trident leaf-nosed bats), Anthops (flower-faced bats), Aselliscus (trident bats), Cloeotis (Percival's trident bat), Coelops (tailless leaf-nosed bats), Paracoelops (orange leaf-nosed bat), Rhinonicteris (orange leaf-nosed bat), and Triaenops (trident bats). Hipposiderids live in tropical and subtropical regions of Africa, south Asia, Australia, the Philippine Islands, and the Solomon Islands. They can be found in deserts, dunes, savannas, grasslands, forests, rainforests, scrub forests and mangroves. Most species roost in dark, enclosed spaces, but some do roost in open areas. Hipposiderids range from 28 to 110 mm in body length, 30 to 110 mm in forearm (wing) length, and may or may not have a tail, up to 60 mm in length. Colors range from white to red to dark brown depending on species, geographic area, sex, and age, and pelage also varies in length and texture. They may have small or large ears, and some species’ ears are interconnected along the dorsal surface of the head. The appearance of the noseleaf is highly variable among genera. Hipposiderids show a great deal of diversity in roosting behavior and reproductive habits and show slight differences in feeding habits from genus to genus.
