VOUCHER MATERIAL (TOTAL = 4): Jenaro Herrera (MUSM 5585), Nuevo San Juan (MUSM 15277), Quebrada Betilia (MUSA 15157), Quebrada Pantaleón (MUSA 15257); see table 21 for measurements.

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Anoura caudifer is a widespread species distributed across French Guiana, Suriname, Guyana, Venezuela, Colombia, Ecuador, Peru, Bolivia, northern Argentina, and northern and southern Brazil (Griffiths and Gardner, 2008a; Oprea et al., 2009). This species is easily distinguished from other congeners by external and craniodental features including the following traits: presence of a short tail; a welldeveloped calcar that is slightly shorter than the foot; a wide, sparsely haired uropatagium with a large U-shaped cutout from the trailing edge; a lower lip that protrudes less than 3 mm beyond

the upper lip; a mesopterygoid fossa with a median keel that is not flattened posteriorly and that usually extends into a septum between the basisphenoid pits; and a last upper premolar that lacks a medial internal cusp (Griffiths and Gardner, 2008a; Oprea et al., 2009; López-Baucells et al., 2018). Descriptions and measurements of A. caudifer were provided by Husson (1962), Handley (1984), Brosset and Charles-Dominique (1990), Molinari (1994), Simmons and Voss (1998), Lim et al. (2005), Mantilla-Meluk and Baker (2006), Oprea et al. (2009), and Velazco and Patterson (2019). No subspecies are cur- rently recognized (Simmons, 2005; Griffiths and Gardner, 2008a; Oprea et al., 2009).

Ascorra et al. (1993), Fleck et al. (2002), and Medina et al. (2015) correctly identified their material of Anoura caudifer from Jenaro Herrera, Nuevo San Juan, Quebrada Betilia, and Quebrada Pantaleón. The voucher material we examined from the Yavarí-Ucayali interfluve conforms to previous descriptions of A. caudifer , with measurements that fall within the range of size variation previously documented for the species.

REMARKS: The only specimen of Anoura caudifer accompanied by capture information

and Choeroniscus minor from the Yavarí-Ucayali Interfluve

from our region is an adult female that was found roosting beneath the undercut bank of a small stream in primary upland forest near Nuevo San Juan on 30 September 1999. The diurnal refugia of Anoura caudifer have seldom been described, but Griffiths and Gardner (2008a: 228) reported that this species was found roosting beneath the undercut banks of forest streams at another Amazonian locality.
