Subfamily Desmodontinae Wagner, 1840

Commonly known as vampires, three extant desmodontine species, each in its own genus, are currently recognized (Kwon and Gardner, 2008; Simmons and Cirranello, 2020). Members of this subfamily are characterized by having a reduced noseleaf with a smooth internarial region and thin, free, flaplike lateral edges; two chin pads with smoothly rounded edges, one on either side of the midline; a uropatagium that is reduced to a narrow, ridgelike band of skin; lack of an external tail; sharp, caninelike incisors; reduced molars and premolars; and wing digit III with three bony phalanges (Kwon and Gardner, 2008; Cirranello et al. 2016). We recorded two vampire species in the Yavarí-Ucayali interfluve; the third species, Diaemus youngii , is expected to occur in our region (appendix 2), but it has yet to be collected or observed there.
