Eptesicus Rafinesque, 1820

The genus Eptesicus is nearly worldwide in distribution and includes 35 currently recognized species (Simmons, 2005; Simmons and Cirranello, 2020). These bats are characterized by medium to large size; a large premolar adjacent to the upper canine (no gap in the toothrow behind the canine); well-developed upper incisors with the inner teeth larger than the outer teeth; and three subequal, trifid lower incisors, the third of which has a wider crown than either of the first two (Miller, 1907; Davis and Gardner, 2008; Reid, 2009; Sánchez et al., 2019). Davis and Gardner (2008) provided a key to the New World species of the genus. During the 2012 CEBIO bat course, three acoustic forms of Eptesicus were detected ( E. brasiliensis , E. cf. brasiliensis , and E. cf. furinalis ), but only two species ( E. brasiliensis and E. furinalis ) have been collected in the Yavarí-Ucayali interfluve. Based on range maps only E. brasiliensis and E. furinalis are expected to occur in our region, so it is not clear whether the third acoustic form detected in 2012 represents an unrecognized species or aberrant calls of E. brasiliensis .
