Abstract. Diving beetles (Dytiscidae) have an impressively diverse array of sexual strategies and associated morphologies and behaviors. These strategies range from extensive preinseminatory syndromes including sexual antagonism in which males attempt to force matings to remarkable postinseminatory selection including extremely complex female reproductive tracts and coevolving variation in sperm morphology including heteromorphism and sperm conjugation. This talk reviews this complex range of variation in diving beetles and places it within the context modern sexual selection theory.
