Abstract: In the present thesis an acoustic and morphometric approach to patterns of variation and divergence of south European cicadas, with emphasis on the genus Cicada L. was carried out. This allowed the outcome of a revised list of all the cicada species known to occur in Portugal, as well as the first description of the calling song of Euryphara contentei based on material from the type locality. A more thorough characterization of the genus Cicada was performed and the new species Cicada cretensis Quartau & Simões, 2005 was described to science. Knowledge on the biogeography and on the structure and patterns of variation in acoustic signals and morphometrics of the species within this genus was significantly increased. A clear geographical separation between C. orni and C. mordoganensis was found in the Aegean area, the former species being present in the west and central localities, while the latter occurs in the eastern part of the area. In C. orni, populations from SE Europe appeared to be acoustically differentiated through longer inter-echeme durations. The biogeography of the genus proved to be correlated with the tectonical evolution of the Aegean area. Therefore, paleogeography may be considered one of the major factors responsible for the present levels of endemism and patterns of distribution in the genus Cicada. Morphometric analysis in sizeand shape revealed that C. lodosi and C.barbara are the species morphologically more divergent, aresult in agreement with the acoustic data. However, divergence is less pronounced in morphologythan at the acoustic level. In the genus Cicada, the calling song appeared to have an important roleboth in long and short range communication, therefore acting as a Specific Mate RecognitionSystem (SMRS). Echeme and syllable rate are possibly the acoustic parameters with more relevantinformation in species recognition and mate choice.
