Tasmanian hairy cicada Tettigarcta tomentosa, copyright Simon Grove.

Belongs within: Auchenorrhyncha.
Contains: Cercopoidea, Tibicinidae, Cicadidae, Cicadellidae, Membracidae.

The Clypeata are the crown clade of living species of the Cicadomorpha. They are characterised by a large, swollen postclypeus, and probably ancestrally feed on xylem (some subgroups feed on phloem or mesophyll) (Shcherbakov & Popov 2002). Three ocelli are present on the crown of the head in members of the Cicadoidea whereas members of Cercopoidea and Cicadelloidea possess only two ocelli in various positions or lack ocelli entirely. Cicadelloidea have longer hind tibiae, more angular in cross section and usually more spinose, than the short, cylindrical hind tibiae of Cercopoidea (Carver et al. 1991). Within the Cicadoidea, the hairy cicadas of the Tettigarctidae differ from other cicadas in having fore wings with the radial sector (RP) arising near the base of the wing and veins CuP and 1A separated, and a long pronotum that overreaches the mesonotum (Carver et al. 1991).
