The Italian stag beetles, morphologically well distinguishable in allopatry, display a mosaic of characters in areas of sympatric occurrence. The mtDNA evidenced that the two species represent well-defined genetic entities and the morphological mosaics could be the result of either hybridization or of a convergence under local selective pressures in areas of sympatric occurrence. The nuclear marker was uniformly polymorphic across the two species, probably due to its recent divergence and was not able to reveal hybridization.
