Genus Vampyriscus Thomas, 1900

Previously ranked as a subgenus of Vampyressa (e.g., by Simmons, 2005), Vampyriscus is now considered a distinct genus that includes three currently recognized species (Arroyo-Cabrales, 2008c; Simmons and Cirranello, 2020). Species of Vampyriscus can be distinguished from members of other stenodermatine genera by the following combination of characteristics: noseleaf with a well-defined median rib; uropatagium relatively narrow and sparsely haired; rostrum shorter than braincase; first upper incisors long, separated basally, and with pointed or weakly bifid tips; basisphenoid pits shallow; lower first premolar not caniniform; and only two upper molars present (Arroyo-Cabrales, 2008c). We recorded both species of Vampyriscus that are expected to occur in the Yavarí-Ucayali interfluve.
