External and Craniodental Measurements (mm) and Weights (g) of Artibeus glaucus

and A. gnomus from the Yavarí-Ucayali Interfluve

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Artibeus cinereus can be distinguished from other small Artibeus by the following combination of characteristics: grayish to brownish dorsal pelage; tetracolored (four-banded) dorsal fur; distinct white facial stripes; margins of ear pale cream or whitish; entire forearm covered by long, dense fur; uropatagium blackish and naked (hairless); rostrum short, broad, not elevated, and lacking a dorsal concavity; posterior border of hard palate V-shaped, with nearly straight sides; impression of optic nerve in orbit well developed; angular process well developed and reaching the level of the condyloid process; second upper premolar noncaniniform; M1 with narrow talon; and m3 absent (Marques-Aguiar, 2008a; Díaz et al., 2016; Rocha et al., 2018a; Arroyo-Cabrales, 2019). Descriptions and measurements of A. cinereus were provided by Andersen (1908), Husson (1962, 1978), Davis (1970), Swanepoel and Genoways (1979), Webster and Jones (1980), Brosset and Charles-Dominique (1990), Simmons and Voss (1998), and Scultori et al. (2009b). Two subspecies are currently recognized: A. c. cinereus (Amazon basin and eastern Brazil) and A. c. quadrivittatus ( Venezuela, the Guianas, and northern Brazil) (Marques-Aguiar, 2008a).

Medina et al. (2015) correctly identified their material from Quebrada Betilia, Quebrada Lobo, and Quebrada Pantaleón as Artibeus cinereus . All the voucher material we examined from the Yavarí- Ucayali interfluve conforms to previous descriptions of the nominotypical subspecies, with measurements that fall within the range of size variation previously documented for that taxon.

REMARKS: No ecological information is currently available for specimens of Artibeus cinereus collected in our region.
