Uroderma magnirostrum Davis, 1968

Figure 27B

VOUCHER MATERIAL (TOTAL = 3): Isla Padre (MUSM 4362, 4364), Jenaro Herrera (MUSM 5595); see table 50 for measurements.

UNVOUCHERED OBSERVATIONS: One individual each of Uroderma magnirostrum were captured at Quebrada Curacinha and Quebrada Limera during the Yavarí Rapid Biological Inventory (Escobedo, 2003). Additionally, we captured one individual at El Chino Village on 18 February 2019.

IDENTIFICATION: This is a widespread but apparently uncommon species distributed from Mexico to eastern Brazil (Gardner, 2008i; Reid, 2009). Uroderma magnirostrum is easily distinguished from other congeneric species by its paler dorsal and ventral pelage ; less prominent facial

stripes; dorsal surface of uropatagium hairy beyond the level of the knees; rostrum deep; dorsal profile from crown to tip of snout nearly a straight line; and mesethmoid greatly expanded, broad, and shield shaped in frontal view (Davis, 1968; Gardner, 2008i; López-Baucells et al., 2018). Descriptions and measurements of U. magnirostrum were provided by Davis (1968), Swanepoel and Genoways (1979), Willig (1983), and Nogueira et al. (2003). No subspecies are currently recognized (Gardner, 2008i).

Ascorra et al. (1993) correctly identified their specimen from Jenaro Herrera. The voucher material we examined from the Yavarí-Ucayali interfluve conforms to previous descriptions of Uroderma magnirostrum , with measurements that fall within the range of size variation previously documented for the species.

REMARKS: Escobedo (2003) reported capturing Uroderma magnirostrum over a stream at Quebrada Limera, and the individual captured at El Chino Village was taken in a ground-level mistnet in a clearing.
