Nycteridae is one of the twenty families ofbats in themammalianorderChiroptera and part of themicrobat suborder. Members of this family are called nycterids or slit-faced bats. They are found in Africa, theArabian Peninsula, and southeastern Asia, primarily in forests andsavannas, though some species can also be found in deserts,shrublands, grasslands, or caves. They range in size from thedwarf slit-faced bat, at 3 cm (1 in) plus a 3 cm (1 in) tail, to thelarge slit-faced bat, at 9 cm (4 in) plus a 9 cm (4 in) tail. Like all bats, nycterids are capable of true and sustainedflight, and have forearm lengths ranging from 3 cm (1 in) to 7 cm (3 in). They are allinsectivorous and eat a variety of insects and spiders, and the large slit-faced bat also regularly eats fish, frogs, birds, and bats.[1] No nycterids have population estimates or are categorized asendangered species.
The 16 extant species of Nycteridae are all contained in a singlegenus,Nycteris. A few extinct prehistoric nycterid species have been discovered, though due to ongoing research and discoveries the exact number and categorization is not fixed.[2]

Conservation status codes listed follow theInternational Union for Conservation of Nature (IUCN)Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the nycterid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted.
ThefamilyNycteridae consists of sixteen species in a singlegenus,Nycteris.
The following classification is based on the taxonomy described by the reference workMammal Species of the World (2005), with augmentation by generally accepted proposals made since usingmolecular phylogenetic analysis, as supported by both the IUCN and theAmerican Society of Mammalogists.[3]
