(see text) Ischnorhinidae is the second largest family of Cercopoidea, a xylem-feeding insect group, formerly included in the family Cercopidae, and similarly commonly called froghoppers.
[1] They belong to the hemipteran suborder Auchenorrhyncha.
A 2023 phylogenetic study of the superfamily indicated the elevation of the New World cercopid subfamily Ischnorhininae to full family status as Ischnorhinidae was necessaryin order to create a monophyletic Cercopidae, thereby now restricted exclusively to the Old World.
[2] This was based on the closer phylogenetic ties of Ischnorhinidae to Machaerotidae than to the remaining Cercopidae.
[2] The Cercopidae senso stricto was then divided into two monophyletic subfamilies, Cercopinae and Cosmoscartinae, each with a number of tribes.
