This small bat is recorded in northern South America, including Guyana and French Guiana. Guyanese specimens had pale-gray belly fur and distinctive ear hairs; captures came from forest trails and waterways.
Guyanese specimens had pale-gray ventral fur, short hairs on the front edge of the ears, and a calcar longer than the hindfoot.
One bat was netted about 8 p.m., roughly 1 m above ground along a trail in disturbed alluvial forest near Iwokrama. Other records came from a river, Wallaba bush, and terra firme forest.
