Carollia benkeithi Solari and Baker, 2006

VOUCHER MATERIAL (TOTAL = 22): Jenaro Herrera (CEBIOMAS 92; MUSM 820, 822, 825, 827, 852, 853, 5552), Nuevo San Juan (AMNH 272661, 272735, 272750, 272751, 272758, 272759, 272774, 272805, 272853; MUSM 13185), Quebrada Blanco (MUSM 21126), Quebrada Lobo (MUSA 15135), Quebrada Pantaleón (MUSA 15246, 15247); see table 15 for measurements.

UNVOUCHERED OBSERVATIONS: During the Yavarí Rapid Biological Inventory, individuals of Carollia benkeithi (previously identified as C. castanea ) were captured at Quebrada Curacinha (two individuals) and Quebrada Limera (one individual) (Escobedo, 2003). One individual of C. benkeithi (also identified as C. castanea ) was captured at Divisor during the Sierra del Divisor Rapid Biological Inventory (Jorge and Velazco, 2006). One additional individual was captured at El Chino on 18 February 2019.

IDENTIFICATION: Although Carollia benkeithi can be distinguished from most other congeneric species by its small size (forearm <38 mm), it is easily confused with its allopatric congener C. castanea , which is similar in size and other external characteristics. However, Carollia benkeithi can be distinguished from C. castanea based on craniodental features, including a well-developed anterior cingulum on the second upper premolar (this cingulum is less developed in C. castanea ), and a second upper premolar that is usually oriented in line with the long axis of the skull, resulting in an obvious “step” between the labial margins of the second premolar and the first molar (this “step” is less obvious in C. castanea ; McLellan and Koopman, 2008). Descriptions and measurements of C. benkeithi were provided
