Clypeorrhyncha Sorensen et al., 1995 Cicadomorpha[1] is an infraorder of the insect order Hemiptera which contains the cicadas, leafhoppers, treehoppers, and spittlebugs.

Distributed worldwide, all members of this group are plant-feeders, and many produce either audible sounds or substrate vibrations as a form of communication.

Some authors use the name Clypeorrhyncha (from the Latin clypeus and the Greek ῥύγχος rhúnkhos, 'shielded nose') as a replacement for the extant Cicadomorpha.

Most Cicadomorphas have a filter chamber in their mid-gut which helps remove excess water from the xylem or phloem sap that they feed on.

[3] Of the three extant superfamilies within the Cicadomorpha, molecular phylogeny studies have placed Membracoidea as a sister group to a clade containing Cicadoidea and Cercopoidea.
