VOUCHER MATERIAL (TOTAL = 14): Estación Biológica Madre Selva (MUSM 32445, 32446), Jenaro Herrera (AMNH 278509; MUSM 5531, 5929), Nuevo San Juan (AMNH 272733, 272734; MUSM 13161, 13162, 15158), Quebrada Vainilla (LSUMZ 28424, 28425), Santa Cecilia (FMNH 87030, 89157); see table 38 for measurements.

UNVOUCHERED OBSERVATIONS: One individual of Artibeus lituratus was captured at Tapiche during the Sierra del Divisor Rapid Biological Inventory (Jorge and Velazco, 2006). Additionally, we caught 16 individuals of A. lituratus at El Chino Village between 16 and 21 February 2019.

IDENTIFICATION: Artibeus lituratus can be distinguished from other congeners by its large size (forearm> 63 mm); brownish dorsal and ventral pelage; ventral pelage without pale frosting; well-defined, bright-white facial stripes; furred dorsal surface of uropatagium; weakly developed hypocone on M1; and by the absence of M3 (Marques-Aguiar, 2008a; López- Baucells et al., 2018). Descriptions and measurements of A. lituratus have been provided by Goodwin and Greenhall (1961), Tamsitt and Valdivieso (1966), Swanepoel and Genoways (1979), Davis (1984), Koepcke and Kraft (1984), Handley (1987), Brosset and Charles-Dominique (1990), Lim and Wilson (1993), Marques- Aguiar (1994), Simmons and Voss (1998), Rui et al. (1999), Lim et al. (2005), Marchan-Rivadeneira et al. (2012), and Velazco and Patterson (2019). Two subspecies are currently recognized: A. l. lituratus (cis-Andean tropical and subtropical South America from southern Venezuela to northern Argentina) and A. l. palmarum (southeastern Mexico south to northern and western Colombia, northern Venezuela, Trinidad and Tobago, and the Lesser Antilles) (Marques-Aguiar, 2008a; Larsen et al., 2013). beus lituratus captured at Jenaro Herrera;

brada Blanco; and C, an adult A. planiros-

tris captured at El Chino Village.

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

and A. lituratus from the Yavarí-Ucayali Interfluve

Ascorra et al. (1993) and Fleck et al. (2002) correctly identified their material from Jenaro Herrera and Nuevo San Juan, respectively, as Artibeus lituratus . The voucher material we examined from the Yavarí-Ucayali interfluve conforms to previous descriptions of the nominotypical subspecies, with measurements that fall within the previously documented range of size variation for that taxon.

REMARKS: Of 41 nocturnal captures of Artibeus lituratus accompanied by ecological data from our region, 22 were made in ground-level mistnets, 18 in elevated nets, and 1 in a harp trap. Of these mistnet and harp-trap captures, 17 were in primary forest, 2 were in secondary vegetation, and 22 were in clearings. The only roost we found of this species was beneath an apparently unmodified frond of Oenocarpus bataua (Arecaceae) about 3 m above the ground in primary hilltop forest near Nuevo San Juan; this roost was inhabited by a single adult male that we collected on 11 November 1999. Palm-frond roosts of Artibeus lituratus are sometimes modified by biting to provide inconspicuous toeholds (Muñoz-Romo and Herrera, 2003); we cannot rule out the possibility that the frond from which our specimen was collected was similarly modified because we had no opportunity to inspect it closely.
