VOUCHER MATERIAL (TOTAL = 7): Isla Muyuy (MUSM 21266), Jenaro Herrera (MUSM 5922, 5924, 5925), Nuevo San Juan (MUSM 13260), Quebrada Pantaleón (MUSA 15262), Santa Cecilia (FMNH 87058); see table 48 for measurements.

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Sturnira giannae is a widespread Amazonian species that also occurs on the eastern slopes of the Andes (Velazco and Patterson, 2019). Sturnira giannae is distinguished from other congeners by the following combination of characteristics: dorsal fur short and bicolored; ventral fur short and monocolored; shoulder glands (epaulettes) present; trailing edge of the uropatagium covered with short hairs; anterior process of the glenoid fossa welldeveloped; inner upper incisors bicuspidate and slender; inner and outer lower incisors tricuspidate and subequal in height; and lower-molar metaconids and entoconids well defined and separated by a deep notch (Velazco and Patterson, 2019). A description and measurements of S. giannae were provided by Velazco and Patterson (2019). No subspecies are currently recognized (Velazco and Patterson, 2019).

Specimens from Jenaro Herrera, Nuevo San Juan and Quebrada Pantaleón were previously identified by Ascorra et al. (1993), Fleck et al.

and S. tildae from the Yavarí-Ucayali Interfluve

(2002), and Medina et al. (2015), respectively as Sturnira lilium . Voucher material from the Yavarí-Ucayali interfluve conforms to Velazco and Patterson’s (2019) description of S. giannae in all qualitative and quantitative respects.

REMARKS: The only specimen of Sturnira giannae accompanied by capture information from our region was taken in a ground-level mistnet in a swampy mineral lick (collpa) near Nuevo San Juan.
