The male genital stylus of a southern Ohio population of Merope tuber is dimorphic in the length in both of its segments. This dimorphism is not paralleled in their overall size as indicated by fore wing length nor is it apparent in the females. The styli are positively allometric, resulting in conspicuous differences between the smallest and largest males. The precise function of the styli and the proximate and ultimate causes of the dimorphism are unknown.
