VOUCHER MATERIAL (TOTAL = 15): Estación Biológica Madre Selva (MUSM 32809); Jenaro Herrera (CEBIOMAS 97; MUSM 4221, 4222,

6971), Quebrada Betilia (MUSA 15149), Quebrada Esperanza (FMNH 89079, 89080), Quebrada Lobo (MUSA 15146), Río Blanco (MUSA 15066, 15074, 15079, 15097, 15098), Santa Cecilia (FMNH 87035); see table 43 for measurements.

UNVOUCHERED OBSERVATIONS: Four individuals of Chiroderma villosum were captured at El Chino Village on 21 February 2019.

IDENTIFICATION: Chiroderma villosum is easily distinguished from other species in the genus by the following combination of characteristics: medium size (forearm> 40 mm, greatest length of skull> 23 mm); pale facial and dorsal stripes inconspicuous or absent; and upper inner incisors slender and parallel (not convergent) (Gardner, 2008e; López-Baucells et al., 2018; Garbino et al. 2020). Descriptions and measurements of C. villosum were provided by Goodwin and Greenhall (1961), Husson (1962, 1978), Hill (1964), Ceballos-Bendezú (1968), Baker and Genoways (1976), Carter and Dolan (1978), Genoways and Williams (1979), Swanepoel and Genoways (1979), Brosset and Charles-Dominique (1990), Simmons and Voss (1998), Lim et al. (2005), Taddei and Lim (2010), Garbino et al. (2012), and Rocha et al. (2016 [who reported Brazilian specimens misidentified as C. salvini ]). Two subspecies are currently recognized: C. v. jesupi (western Mexico to northwestern Peru and northern Colombia) and C. v. villosum (east of the Andes in tropical South America) (Gardner, 2008e; Garbino et al. 2020).

Ceballos-Bendezú (1968), Ascorra et al. (1993), and Medina et al. (2015) correctly identified their material from Quebrada Esperanza, Jenaro Herrera, Quebrada Lobo, and Río Blanco as Chiroderma villosum . Medina et al. (2015) erroneously reported an adult female specimen from Quebrada Betilia (MUSA 15149) as Chiroderma salvini , but Garbino et al. (2020) correctly identified that specimen as C. villosum . 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: Of six specimens of Chiroderma villosum accompanied by capture data from our region, two were taken in ground-level mistnets and four in elevated nets; all of these specimens were captured in clearings. No roosting groups of this species were encountered during our study.
