Cicadomorpha

Classification

Some authors use the name Clypeorrhyncha (from the Latin clypeus and the Greek ῥύγχος rhúnkhos, 'shielded nose') as a replacement for the extant Cicadomorpha. Nymphs of many Cicadomorphans coat themselves with secretions from specialized Malphigian tubules. They are never coated with hydrophobic wax as seen in the nymphs of Fulgoromorpha. 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.

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. Within these superfamilies, not all deep phylogeny questions have been resolved.
