VOUCHER MATERIAL (TOTAL = 34): Isla Muyuy (MUSM 21157, 21158), Jenaro Herrera (AMNH 278497; CEBIOMAS 99; MUSM 5511, 5521, 5522, 5538–5540, 5587, 5588, 5930, 5939), Nuevo San Juan (AMNH 273097, 273128, 273191, 273194; MUSM 13204, 15195–15199), Orosa (AMNH 74012, 74014, 74015, 74111, 74112), Quebrada Blanco (MUSM 21159, 21160), Quebrada Esperanza (FMNH 89110, 89111), Quebrada Lobo (MUSA 15133); see table 22 for measurements.

UNVOUCHERED OBSERVATIONS: An unspecified number of individuals of Glossophaga soricina were captured at Wiswincho during the Tapiche-Blanco Rapid Biological Inventory (Escobedo-Torres, 2015).

IDENTIFICATION: Glossophaga soricina occurs throughout most of the rainforested lowlands of cis-Andean South America (Hoffmann et al., 2019; Calahorra-Oliart et al., 2021). This species is distinguished from other congeners by its domed, rounded braincase; well-developed mandibular symphyseal ridge; large, procumbent inner upper incisors that extend anteriorly well beyond the outer upper incisors; a well-devel-

oped parastyle on M1; crowded lower incisors that are usually in contact with one another and with the canines; well-developed mesostyles on m1 and m2; and relatively dark pelage (Alvarez et al., 1991; Webster, 1993; Griffiths and Gardner, 2008a; Calahorra-Oliart et al., 2021). Descriptions and measurements were provided by Miller (1913a), Goodwin and Greenhall (1961), Husson (1962), Alvarez et al. (1991), Webster (1993), Simmons and Voss (1998), Lim et al. (2005), Griffiths and Gardner (2008a), Velazco and Patterson (2019), and Calahorra-Oliart et al. (2021). Following a recent revision that elevated formerly conspecific populations from west and north of the Andes to species level, no subspecies are currently recognized in G. soricina (Calahorra-Oliart et al., 2021) .

Ceballos-Bendezú (1968), Ascorra et al. (1993), Fleck et al. (2002), and Medina et al. (2015) correctly identified their specimens from Quebrada Esperanza, Jenaro Herrera, Nuevo San Juan, and Quebrada Lobo, respectively, as Glossophaga soricina . All the voucher material we examined from the Yavarí-Ucayali interfluve conforms to previous descriptions of the nominotypical subspecies, and measurements of our material fall within the range of size variation previously documented for that taxon.

REMARKS: Specimens of Glossophaga soricina accompanied by capture data from our region include six individuals taken in ground-level mistnets and three taken in elevated nets ; of these, eight were netted in clearings and one was netted in primary forest. We found three roosts of Glossophaga soricina near Nuevo San Juan. The first (occupied by three individuals, of which one adult female was captured on 17 September 1999) was beneath the undercut bank of a small stream in seasonally flooded forest ; another roost (occupied by two individuals, of which one adult female was captured on 1 October 1999) was inside a hollow log in seasonally flooded forest; and the third roost (occupied by an unknown number of individuals, of which two adult males, two adult females, and three immature males were captured between 5 and 8 November 1999) was inside a hollow log in primary upland forest. The first two roosts were occupied only by G. soricina , but the third was shared with Carollia brevicauda .

Glossophaga soricina has been found roosting in a wide range of situations in South America and seems appropriately considered a roost generalist (Voss et al., 2016).
