The fur is dark chocolate brown in colour, and only slightly paler on the underside than on the rest of the body.

The most distinctive feature is a narrow band of white hair running along each flank to the forward part of the mesopatagium.

The ears are large and rounded, positioned close together at the base, and mostly hairless, with a small tragus and long antitragus.

The uropatagium is also furred for about a third of its area, and is bounded by long calcars running for about three quarters of the length of the membrane edge.

[2] Little is known of the bat's habitat preferences, but it has been found in humid lowland evergreen forests and pine plantations.
