Desmodus rotundus

(É. Geoffroy St.-Hilaire, 1810)

VOUCHER MATERIAL: El Diamante: 2 adult females ( FMNH 203336 ; MUSM 39183 ), 8 adult males ( FMNH 203332 , 203334 , 203516 , 203518 , 203520 ; MUSM 39184 , 39185 , 39186 ) ; Tingana: 1 adult female ( MUSM 39187 ) ; Waqanki: 4 adult females ( FMNH 203330 , 203514 ; MUSM 39180 , 30182 ), 1 adult male ( MUSM 39181 ) ; see table 6 for measurements.

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.
