Husson's yellow bat is primarily distinguished from other species in the genus Rhogeessa by its fur colour. Both its ventral and dorsal fur is golden brown with brown tips. Its muzzle is similar to that found in the genus Eptesicus with more obvious pads than R. io. Cranial measurements including breadth of the upper canines and palate, and the length of the teeth across the maxillary bone were all larger in Husson's yellow bat.
