Within Phyllostomidae is the subfamily Stenodermatinae, members of which are sometimes called tailless bats. These 17 genera from Central America have broad shoulders and faces and narrow tail membranes, with a tail that is either greatly reduced or absent. The upward projection of their noseleaf has two creases and the lower part is at least partly free. The shape of their faces has been correlated to their frugivorous diet. They are known to pick fruit with their mouths and carry it to a night roost to consume it. Thus, they are important seed dispersers for certain plants.
