| Only its chromosomes distinguish Genoways’s Yellow Bat from the Black-winged Little Yellow Bat. These tiny bats are so similar that no single characteristic can distinguish one from the other, but where both species occur there are no hybrids, confirming their separate identities. Both have small, rounded ears, relatively thick, strong wings, and broad tail membranes that lack fur. They have relative long tails that extend the full length of the tail membrane. They are among the first bats to leave their day roosts to feed when night comes, and have been netted under the canopy in mature lowland tropical forests. No information is available about their reproductive habits, and no fossils of this bat have been found.
Head and Body: 37-50 mm; Tail: 27-33 mm
