Abstract. Postmating sexual selection theory predicts that in allopatry reproductive traits diverge rapidly and that
the resulting differentiation in these traits may lead to restrictions to gene flow between populations and, eventually,
reproductive isolation. In this paper we explore the potential for this premise in a group of damselflies of the family
Calopterygidae, in which postmating sexual mechanisms are especially well understood. Particularly, we tested if in
allopatric populations the sperm competition mechanisms and genitalic traits involved in these mechanisms have
