Family Emballonuridae Gervais, 1856

The pantropical family Emballonuridae (commonly known as sheath-tailed or sac-winged bats) includes 55 currently recognized Recent species in 14 genera, of which 22 species in 8 genera are Neotropical (Simmons, 2005; Simmons and Cirranello, 2020). These rather delicate bats are characterized externally by long, soft fur; lack of facial ornamentation; relatively large eyes; and presence of a broad uropatagium, from which the tip of the tail emerges dorsally about halfway along the length of the membrane (Emmons and Feer, 1997; Simmons and Voss, 1998; Hood and Gardner, 2008; Reid, 2009; López-Baucells et al., 2018). Most Neotropical emballonurids have glandular wing sacs located in the propatagium near the elbow (Emmons and Feer, 1997; Reid, 2009; López-Baucells et al., 2018). Hood and Gardner (2008) provided a key to the genera and species of South American emballonurids based on external and craniodental characters. Eleven species in six genera are known from the Yavarí-Ucayali interfluve. Published records from localities adjacent to the Yavarí-Ucayali interfluve include another two emballonurid species that might also occur in our study area (appendix 2).
