Uroderma bilobatum Peters

VOUCHER MATERIAL: 10 females (AMNH *266257, *267174, *267177, *267178, *267465, *267469; MNHN 1995.1173, *1995.1174, *1995.1175, *1995.1176) and 13 males (AMNH *267171, *267175, *267176, *267183, *267463, *267464, *267470, *268563, *268565; MNHN *1995.1177, *1995.1178, *1995.1179, *1995.1180); see table 47 for measurements.

IDENTIFICATION: The principal reference on bats of the genus Uroderma is Davis (1968), who described the species in detail and provided figures and measurements. Helpful descriptions and comparative measurments of U. bilobatum can also be found in Goodwin and Greenhall (1961), Husson (1962, 1978), Swanepoel and Genoways (1979), Baker and Clark (1987), and Brosset and Charles­Dominique (1990). Six subspecies of U. bilobatum are currently recognized, of which the nominate form occurs throughout Amazonia, including the Guianas (Davis, 1968; Baker et al., 1972; Baker and Clark, 1987; Koopman, 1994).

Our voucher material conforms in all respects with published descriptions of this species, and our measurement data fall within the range of variation previously reported for U. b. bilobatum .

FIELD OBSERVATIONS: We captured 25 individuals of Uroderma bilobatum at Paracou, of which 21 were taken in ground­level mistnets and 4 at roosts. Of the 21 ground­level mistnet captures, 6 were in swampy primary forest, 5 were in creekside primary forest, 6 were in manmade clearings, and 4 were over roadside puddles.

We found two roosting groups, each in an ‘‘apical’’ tent (sensu Kunz et al., 1994) made by chewing through the midrib of a large leaf of Phenakospermum guyannense (Strelitziaceae) (fig. 51). A roosting group of three bats collected in its entirety consisted of an adult male, a lactating adult female, and a juvenile. Both roosts were in swampy primary forest; one tent was 3.5 m and the other 5 m above the ground.
