[email protected] Abstract: Based on material collected recently on the island of Crete, in southern Greece, the present study describes a new species of the genus Cicada. The new species is closely related to both C. orni and C. mordoganensis, but can be distinguished from these by characters of the male genitalia and the distinctive calling song, which is illustrated by oscillograms, sonagrams and amplitude spectra. Comparison of the calling song of C. cretensis sp.n.withthoseofC. orni and C. mordoganensis showed considerable differences, especially in the inter-echeme interval, which is in general shorter in the new species than in either C. orni or C. mordoganensis. Moreover, the duration of the echemes of C. cretensis sp. n. is, on average, considerably longer than in C. orni and shorter than in C. mordoganensis. Key words: Hemiptera, Cicada, taxonomy, calling song, new species, Greece, Crete.
