A new cicadellid tribe, Tungurahualini, is recognized to include Tungurahuala Kramer, and a related new genus, Ilyapagen. n., based on six new species. The tribe is included in subfamily Mileewinae, the concept of which is further expanded to include tribes Makilingiini Baker, and Tinteromini Godoy and Webb, taxa previously treated as separate subfamilies. Keys to tribes of Mileewinae (sensu lato) and genera of Tungurahualini are provided. A new species of Tungurahuala, Tungurahuala acuminatasp. n., is also described and keys to species of Tungurahuala and Ilyapa are provided. The new tribe is presently recorded only from cloud forests in the northern Andes Mountains of South America.
