Sundevall's roundleaf bat
Sundevall's roundleaf bat (''Hipposideros caffer''), also called Sundevall's leaf-nosed bat,〔 is a species of bat in the family Hipposideridae.
These bats are very similar in appearance to the closely related Noack's roundleaf bat, and the two have in the past been considered to be the same species. Although more recent research suggests that they are distinct, taken together, they possibly represent a species group containing a number of cryptic species or subspecies that have yet to be distinguished.〔〔Vallo, P., A.

==Description==
Sundevall's roundleaf bat is a medium-sized bat, with a head-body length of , and a wingspan of . Adults have a body weight of . They have long fur, which may be either grey or a bright golden-orange in colour, and brown wings. The fur is generally paler on the underside of the body.
The bats have large, rounded, ears with a well-developed antitragus, and a horseshoe-shaped nose-leaf, with a distinctive small projection on either side. There is also an additional serrated ridge of skin behind the main nose-leaf. Both females and males have an extra pair of teats in the pubic region. Although these are vestigial in the males, they can be as long as in some females (almost half the body length), yet are never functional. These false teats may be only present to allow the young something to hold on to while clinging to their mothers.〔
