Nose-leaf diagram of a horseshoe bat. A nose-leaf, or leaf nose, is an often large, lance-shaped nose, found in bats of the Phyllostomidae, Hipposideridae, and Rhinolophidae families. Because these bats echolocate nasally, this nose-leaf is thought to serve a role in modifying and directing the echolocation call. [1] [2]
The Kolar leaf-nosed bat is placed in the "bicolor" species group, which is characterized by the absence of secondary leaflets on their nose-leaves and a forearm length of 33–44 mm (1.3–1.7 in). [3] It is most closely related to Cantor's roundleaf bat and the fawn leaf-nosed bat; these three species form a clade in the genus Hipposideros. [4]

The transverse leaf is erect and there is no median projection. [4] They have huge ears mainly because of the well developed antitragus, while no tragus is present. [ 5 ] Males have a sac located posterior to the nose which can secrete a waxy substance, thought to be used in attracting mates and status determination.
