For discussion on the authorship of family group names based on Cicada see notes under “ Cicadidae / Cicadinae Latreille, 1802 ”, p. 387.

Type genus. Cicada L. (type species Cicada orni L.).

Included subfamilies. Cicadinae Latreille , Cicadettinae Buckton n.stat., Tettigadinae Distant .

Diagnosis. Thoracic ganglia fused. Pronotum smaller than mesonotum; paramedian and lateral fissures present; pronotal collar present. Mesonotum with a cruciform elevation. Fore wing vein RP arising from node; veins 2A and 3A fused; nodal line usually indistinct. Hind wing hamulus absent. Pretarsal empodia absent. Hind coxae not overhanging abdomen. Timbals present in males only. Male abdominal resonant chamber present. Tympana present in both sexes. Male sternite VIII shielding genitalia ventrally. Male genitalia with styles absent; basal lobe present; aedeagus never with a sclerotized subdorsal crest. Male reproductive system with testes located posteriorly, centred over abdominal sternite VI. Female genitalia either monotrysian or ditrysian. Female reproductive system with accessory glands of common oviduct present. Nymphs with antennal segments 1 (scape) and 2 (pedicel) together longer than segment 5 (3rd flagellomere); fore femur with no midlateral spine on outer face; fore tibiae subapical tooth absent or weakly developed and not opposing apical tooth; mid and hind tibiae with no stout spines along shank; hind tibiae with spines of spinal crown all similar.

Distinguishing characters. The following attributes are believed to differentiate the Cicadidae . Pronotum smaller than mesonotum; paramedian and lateral fissures present; pronotal collar present. Mesonotum with scutellum forming a cruciform elevation. Fore wing vein RP arising from node; veins 2A and 3A fused. Timbals present in males only or sometimes absent. Male abdominal resonant chamber present. Tympana present in both sexes. Male sternite VIII shielding genitalia ventrally. Male genitalia with basal lobes present. Male reproductive system with testes located posteriorly, centred over spiracles of sternite VI. Female reproductive system with accessory glands of common oviduct present. Nymphs with antennal segments 1 (scape) and 2 (pedicel) together longer than segment 5 (3rd flagellomere); fore femur with no mid-lateral spine on outer face; fore tibiae subapical tooth absent or weakly developed and not opposing apical tooth; mid and hind tibiae with no spines along shank; hind tibiae with spines of spinal crown all similar.

Discussion. The previously held concept of the Cicadidae remains unchanged. Previously identified attributes for the Cicadidae ( Hayashi, 1984; Moulds, 1990) remain applicable.
