A hotspot for Mediterranean cicadas (Insecta: Hemiptera: Cicadidae): new genera, species and songs from southern Spain

Southern Spain exhibits high diversity and endemism. Based on a long-term field study, a review of nine regional cicada species hitherto placed in the genus Tettigetta is provided. According to morphological characters previously defined by Lee, none of these species belongs to the genus Tettigetta; they are placed instead in four new genera: Tettigettalna Puissant gen. nov., Tettigettula Puissant gen. nov., Tettigettacula Puissant gen. nov., and Pseudotettigetta Puissant gen. nov. Tettigetta parvula (Fieber, 1876) and Tettigetta carayoni Boulard (1982) are transferred to Cicadivetta Boulard, 1982, as Cicadivetta parvula (Fieber, 1876), comb. nov. and Cicadivetta carayoni (Boulard, 1982), comb. nov. Tettigetta manueli Boulard, 2000 is considered a synonym of Tettigettalna helianthemi helianthemi (Rambur, 1840), comb. nov., syn. nov. Three new endemics, Tettigettalna boulardi Puissant sp. nov., Tettigettalna armandi Puissant sp. nov., and Tettigettalna defauti Puissant sp. nov., are described. A new subspecies, Tettigettalna helianthemi galantei Puissant ssp. nov., is also reported. All species are described with information on their distribution, habitat selection, and acoustic behaviour. The high diversity of cicadas in southern Spain is discussed in terms of local geography and mating behaviour.
