This shows the distinctive structure on the protarsi of the male, used for grasping the female during mating. "The front tarsus of male Cybister has an elongated triangular palette with many small adhesive seate; that of Dytiscus has two large round adhesive discs and many small adhesive setae in a circular palette" (1). This is illustrated nicely in figure 33 of White (2).
