The thumb is longer than or equal to the width of the wrist measured on the folded wing. The fifth finger of the brush along with the metacarpal bone - about 46 mm long. From a kindred dwarf-dwarf with whom this species was previously mixed, the small bat differs in orange secretion of the facial skin and buccal glands, as a result of which the muzzle, wool (primarily on the head) and genitals in the adult animals have an orange-yellow hue. Also, the maximum energy of echolocation signals in a small bat is about 54 kHz (versus about 46 kHz in a dwarf), which makes it possible to distinguish these types acoustically.
