Family Vespertilionidae Gray 1821

Members of the cosmopolitan family Vespertilionidae are characterized by plain faces lacking a noseleaf; relatively small eyes; wing digit II reduced to the metacarpal plus a single small phalanx; and a long tail that reaches the edge of the uropatagium, and which is entirely enclosed within that membrane (Koopman, 1994; Reid, 2009; López-Baucells et al., 2018). Eight vespertilionid species in three genera ( Eptesicus , Lasiurus , and Myotis ) are expected to occur in the Yavarí-Ucayali interfluve (Davis and Gardner, 2008; Gardner and Handley, 2008; Wilson, 2008b; Moratelli et al., 2013), of which seven were captured and one ( Lasiurus blossevillii ) was detected by acoustic methods.
