==Description== thumb|left|The male (left) is smaller and lighter colored than the female. The species has a particularly marked sexual dimorphism, which originally led naturalists to classify the male and female as distinct species. The male measures 5–6 cm, is light brown and furry. The female is black and measures between 8–9 cm on average, although specimens exceeding 12 cm in length have also been found. The male is nocturnal and can fly, but the female is diurnal and does not fly.
