IDENTIFICATION: Descriptions and measurements of Desmodus rotundus have been provided by Goodwin and Greenhall (1961) , Husson (1962) , Swanepoel and Genoways (1979) , Greenhall et al. (1983) , and Simmons and Voss (1998) . Currently two subspecies are recognized: D. r. murinus (northwestern Mexico southward to northern and western Colombia , and from the Pacific lowlands and western slopes of the Andes in Ecuador and Peru ) and D. r. rotundus ( Trinidad , Venezuela , Guianas, Amazon basin of Colombia , Ecuador , Peru , Brazil , and Bolivia , south through Paraguay and Uruguay into Chile and northern Argentina ) ( Kwon and Gardner, 2008 ). Our specimens conform in all respects to previous descriptions of D. rotundus : thumb greatly elongated, longer than hind foot, and with the presence of two basal pads; ventral sulcus present on tongue; inner lower incisors bicuspidate; and one upper molar on each side ( Goodwin and Greenhall, 1961 ; Kwon and Gardner, 2008 ; Cirranello et al., 2016 ). Our Mayo River basin voucher material belongs to the nominate subspecies. REMARKS: One female (FMNH 203336) that we collected was lactating.
