Review Of The Genus Uroderma (Chiroptera)

The genus Uroderma (order Chiroptera, family Phyllostomatidae) is reviewed. Two species are recognized, both occupying a range from Bolivia and Brazil northward to the Isthmus of Tehuantepec in Mexico. Uroderma bilo-batum Peters, described in 1866, is divided into five geographic races as follows: U. b. bilobatum Peters in eastern Bolivia, Brazil, the Guianas, and most of Venezuela; U. b. thomasi Andersen in western Bolivia, Peru, and Ecuador; U. b. trinitatum, described as new, from the island of Trinidad; U. b. convexum Lyon in western Venezuela, Colombia, most of Panama, and the Pacific versant of Middle America to Oaxaca; U. b. molaris, described as new, in the Atlantic versant of Middle America from western Panama to Veracruz, Mexico. The second species of Uroderma, which is described as new, occurs sympatrically with U. bilobatum. It differs in having a deep, heavy rostrum, a broad, shield-shaped mesethmoid, facial stripes faint or completely lacking, and in lacking an edging of white on the ears.
