Genus Eumops Miller, 1906

The widespread genus Eumops includes 17 currently recognized species (Simmons and Cirranello, 2020). Traits that distinguish this genus from other molossids include large, rounded pinnae that are joined across the forehead and have a greatly developed keel, reduced and pointed or square-tipped tragus, and a large, nearly oval antitragus; smooth (unwrinkled) upper lips; cylindrical skull; well-developed basisphenoid pits; slightly arched palate; long, curved upper incisors; and M3 with a variably developed

third commissure (Eger, 2008; Medina et al., 2014). Eger (1977, 2008) and Gregorin (2009) reviewed the taxonomy and systematics of the genus, and Eger (2008) provided a key to the species based on external and cranial characters. Three acoustic forms of Eumops were detected during the 2012 CEBIO bat course at Jenaro Herrera, of which only E. hansae is documented with voucher material collected in the Yavarí- Ucayali interfluve (the other two acoustic taxa remain unidentified). Five other congeners expected to occur in our region are listed in appendix 2.
