UNVOUCHERED OBSERVATIONS: One individual of Uroderma bilobatum was captured at Tapiche during the Sierra del Divisor Rapid Biological Inventory (Jorge and Velazco, 2006). Additionally, an unspecified number of individuals of U. bilobatum were captured at Quebrada Pobreza during the Tapiche-Blanco Rapid Biological Inventory (Escobedo-Torres, 2015), one individual was captured at the Quebrada Curacinha locality during the Yavarí Rapid Biological Inventory (Escobedo, 2003), and we captured one individual at Tahuayo Farm on 19 February 2019.

IDENTIFICATION: The taxonomy and systematics of the Uroderma bilobatum species complex was recently reviewed by Mantilla-Meluk (2014) and Cuadrado-Ríos and Mantilla-Meluk (2016), who recognized four species: U. bilobatum ; U. convexum and U. davisi , both formerly treated as subspecies of U. bilobatum ; and a newly described species, U. bakeri . As a result, U. bilobatum (sensu stricto) is now restricted to lowland South American populations east of the Andes. Uroderma bilobatum can be distinguished from other congeneric species by the following combination of characteristics: brownish dorsal and ventral pelage; prominent facial stripes; dorsum of uropatagium nearly naked; rostrum not elevated and with a dorsal concavity; interorbital constriction not swollen; and junction of nasals and maxillae forms an obtuse angle in lateral view (Mantilla-Meluk, 2014). Descriptions and measurements of U. bilobatum were provided by Goodwin and Greenhall (1961), Husson (1962, 1978), Ceballos-Bendezú (1968), Davis (1968), Carter and Dolan (1978), Swanepoel and Genoways (1979), Brosset and Charles-Dominique (1990), Simmons and Voss (1998), Lim et al. (2005), Mantilla-Meluk (2014), and Velazco and Patterson (2019). Three subspecies are currently recognized: U. b. bilobatum (Amazonian lowlands and the Atlantic Forest); U. b. thomasi (middle elevations on the eastern slopes of the Andes in Ecuador, Peru, and Bolivia); and U. b. trinitatum ( Trinidad) (Mantilla-Meluk, 2014; Cuadrado-Ríos and Mantilla-Meluk, 2016).

Ceballos-Bendezú (1968), Fleck et al. (2002), and Medina et al. (2015) correctly identified their material from Quebrada Esperanza, Nuevo San Juan, Quebrada Betilia, Quebrada Lobo, and Río Blanco. The voucher material we examined from the Yavarí-Ucayali interfluve conforms to previous descriptions of Uroderma bilobatum bilobatum , with measurements that fall within the range of size variation previously documented for the nominotypical subspecies.

REMARKS: Of nine captures of Uroderma bilobatum accompanied by ecological information from our region, six were made in groundlevel mistnets and three in elevated nets. Of these mistnet captures, three were in primary forest, two were in secondary vegetation, three were in clearings, and one was in a swampy mineral lick (collpa).
