Eumops hansae Sanborn, 1932

VOUCHER MATERIAL (TOTAL = 3): Quebrada Betilia (MUSA 15193), Quebrada Blanco (MUSM 20982), Quebrada Lobo (MUSA 15144); see table 62 for measurements.

UNVOUCHERED OBSERVATIONS: During the CEBIO bat course in Jenaro Herrera, Eumops hansae was recorded using acoustic methods.

IDENTIFICATION: Eumops hansae can be distinguished from other congeneric species by the following combination of characteristics: medium size (forearm 37–41 mm); short, blackish brown dorsal fur; white-based ventral fur; greatest length of skull ca. 50% of forearm length; and long, deep basisphenoid pits (Eger, 2008). Descriptions and measurements of E. hansae were provided by Sanborn (1932), Gardner et al. (1970), Eger (1977, 2008), Brosset and Charles- Dominique (1990), Simmons and Voss (1998), Gregorin (2009), and Medina et al. (2012). No subspecies are currently recognized (Eger, 2008).

Medina et al. (2015) correctly identified their specimens from Quebrada Betilia and Quebrada Lobo as Eumops hansae . The voucher material we examined from the Yavarí-Ucayali interfluve conforms to previous descriptions and measurements of the species.

REMARKS: No ecological information is available about this species from our region.
