Cercopidae are the largest family of Cercopoidea, a xylem-feeding insect group, commonly called froghoppers. They belong to the hemipteran suborder Auchenorrhyncha. A 2023 phylogenetic study of the family suggested the elevation of the New World subfamily Ischnorhininae to full family status as Ischnorhinidae, leaving a monophyletic Old World Cercopinae.
Based on a 2023 molecular phylogenetic analysis, the Cercopidae senso stricto was divided into two monophyletic subfamilies, Cercopinae and Cosmoscartinae, each with a number of tribes.
Crispolon Jr et al. (2023) considered certain described genera as invalid without discussion and did not include them in the family as prescribed by their phylogeny.
Crispolon Jr. et al.s 2023 molocular phylogenetic analysis recommended removing the following genera from Cercopidae and transferring them to Aphrophoridae:
Additionally they recommended the elevation of the subfamily Ischnorhininae, endemic to the Americas, to full family status as Ischnorhinidae. This was based on the closer phylogenetic ties to Machaerotidae then to subfamily Cercopinae found exclusively in Europe, Africa, and Asia, Australasia:
