Abstract
We report an unusual biogeographical disjunction between the Western and the Eastern Mediterranean region. Cornu (Gastropoda: Helicidae) is a Western Mediterranean land snail genus. It includes Cornu (Cornu) aspersum (M?ller), which originated in Northwestern Africa and was distributed by humans as food or accidentally throughout the Mediterranean region and later even to all continents except Antarctica, as well as three species belonging to the subgenus Erctella, which are all endemic to Sicily. We discovered a new species of Cornu on the Greek island of Crete. The morphological and molecular genetic analyses showed that the species from Crete is a disjunct representative of Erctella. We suppose that the disjunction originated by a long-distance dispersal event of the ancestors of the Cretan species from Sicily by birds or by sea currents, perhaps accelerated by a tsunami or a similar event. The Cretan lineage separated from the Sicilian species in the late Miocene or early Pliocene. This divergence time is compatible with the hypothesis that the ancestor of Cornu cretense sp. nov. was washed from Sicily to Crete by the Zanclean flood that refilled the Mediterranean basin after it had dried up during the Messinian salinity crisis.
