Distribution of cicadas of the genus Lyristes (Hemiptera: Cicadidae) in the eastern Mediterranean area

Simões, Paula | Quartau, José
The present study gives an updated overview on the distribution of species of the genus Lyristes Horváth, 1926 in the eastern Mediterranean area. Besides occurring in southern continental Europe, specimens of L. plebejus were also found along the southern Greek mainland and in the western Aegean island of Kithira. Moreover, the new data presented give L. gemellus as a new record for Greece (appearing only along most of the Anatolian coast) as well as for Cyprus. The genus seems to be absent from the Cyclades as well as from the islands of Crete and Karpathos. Therefore, the results revealed a faunal discontinuity between the Greek western and eastern islands in the Aegean Sea. Hence, the persistence of a deep sea barrier between these two groups of islands seems to explain the present distribution of Lyristes species, which is also in accordance with the paleogeography of the area and with the fact that dispersal to more geographically isolated islands might have been virtually impossible for species of this genus.
