Type from Papayo (about 25 miles northwest ofAcapulco), Guerrero, Mexico. The distinguishing characters of the yellow-shouldered bat inPanama are the same as those of the genus. The dark tips of thepelage give the back a dark brown tone, but the under color of thefur is gray. The forearm measures about 44 millimeters.

In these genera a pair of whitestripes extend upward from the sides of the nose leaf to the innerbase of the ears; another pair less distinct reaches from the cornersof the mouth toward the ears, and a median dorsal line is usuallyprominent. But the single species of Uroderma may be distinguishedby the naked or minutely haired posterior margin of the interfemoralmembrane in combination with the length of the forearm (about45 millimeters).
