Genus Lophostoma d’Orbigny, 1836

The genus Lophostoma includes seven species distinguished from other phyllostomines by the following shared characteristics: very large, rounded ears; chin with a U-shaped row of small tubercles; face sparsely furred with short hairs (muzzle may appear nearly naked); skull with narrow postorbital constriction (<5.5 mm; less than 90% of breadth across cingula of canines); and one incisor and three premolars in each mandible (Williams and Genoways, 2008). With live individuals in hand, species of Lophostoma can often be distinguished from superficially similar taxa (e.g., Tonatia spp. , Micronycteris spp. ) by touching their ears: species of Lophostoma typically fold their ears down over the top of the head when touched, whereas other largeeared phyllostomines do not. The taxonomy and systematics of Lophostoma have been reviewed by Davis and Carter (1978), Lee et al. (2002), Porter et al. (2003), Baker et al. (2004), Fonseca and Pinto (2004), Velazco and Cadenillas (2011), Velazco and Gardner (2012), and Camacho et al. (2016). Velazco and Gardner (2012) provided a key to the species, of which we recorded all three that are expected to occur in the Yavarí- Ucayali interfluve.
