Reconstruction of the paleobiogeographic scenario for Parachtes diversification. Scenario 1, 2, 3 and 4 represent main geological events that occurred during the opening of the western Mediterranean Basin. Contemporary areas of species distribution are indicated as follows: Ib, Iberian microplate; Co, Corsica; Sa, Sardinia; Ca, Calabria; Ba, Balearic Islands; Be/Rif, Betic/Rift microplate and Ap, Apulian microplate. Current species distribution is indicated at the tips of the inferred topology, and the colours correspond to areas previously defined. The putative geological event involved in the diversification process is indicated at each node.
