Trinycteris nicefori Sanborn, 1949

VOUCHER MATERIAL (TOTAL = 9): Jenaro Herrera (MUSM 5551), Nuevo San Juan (AMNH 272802, 272840; MUSM 13213, 13214), Quebrada Blanco (MUSM 21302–21305); see table 23 for measurements.

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Trinycteris nicefori is easily distinguished from other phyllostomids by the following combinations of characteristics: the chin has a pair of dermal pads, one on each side of the midline; the dorsal fur is tricolored and either grayish brown or orange; a faint, pale middorsal stripe is present on the lower back; the ear is> 16 mm and tapers to a blunt point; of the

metacarpals, the fourth is the shortest and the third is the longest; the calcar is shorter than the foot; the upper incisors are procumbent, not in line with the canines, distinctly shorter and narrower than those teeth, and not chisel shaped; and the first upper premolar lacks accessory cusps (Sanborn, 1949a; Wetterer et al., 2000; Williams and Genoways, 2008; López-Baucells et al., 2018). Descriptions and measurements of T. nicefori were provided by Sanborn (1949a), Swanepoel and Genoways (1979), Williams and Genoways (1980a), Brosset and Charles-Dominique (1990), Simmons (1996), Simmons and Voss (1998), Lim et al. (2005), and Rocha et al. (2013). No subspecies are currently recognized (Williams and Genoways, 2008).

Ascorra et al. (1993) and Fleck et al. (2002) correctly identified their material from Jenaro Herrera and Nuevo San Juan, respectively, as Trinycteris nicefori . The voucher material we exam- ined from the Yavarí-Ucayali interfluve conforms to previous descriptions of T. nicefori , with measurements that fall within the range of size variation previously documented for the species. Both of the color phases (“red” and “gray”) described by Sanborn (1949a) are present among specimens collected in our region.

REMARKS: The only four specimens of Trinycteris nicefori accompanied by ecological information from our region were captured in ground-level mistnets in the understory of primary upland forest near Nuevo San Juan.
