The little white-shouldered bat is a small
phyllostomid bat, with males measuring and females in total length. The fur is generally brown, being paler underneath, and on the forequarters. As the common name suggests, both sexes have a spot of pure white fur on the shoulders near the base of the neck. The wings are also brown, and the
uropatagium is hairy; the bats do not possess an external tail. The head has a relatively short, broad snout, with a wide mouth, and a simple, spear-like
nose-leaf. The ears are small and triangular, and the eyes large and bulging, with a yellow iris. ==Distribution and habitat==
