Interpretive Summary: Leafhoppers and treehoppers cause millions of dollars of damage in crop loss every year. In order to communicate about known and potential agricultural pests, every species needs to have a name. Nevertheless, this is not the case for many species. In this paper, four new species in a new species group are described. Additionally, this unusual new species group will help elucidate the relationships of all treehoppers. This will be useful for research scientists, federal regulator agencies such as the Animal and Plant Health Inspection Service, and state extension personnel.

Technical Abstract: The new genus Polyodontotrochus is described and illustrated with four new species: P. auriculatus (type species) from French Guiana, P. elevatus from Ecuador, P. extentapalaestrus from French Guiana, and P. inpa from Brazil, and the genus differs from all other membracids in having the inner sides of their metathoracic trochanters developed into apposed, flattened plates with many strongly sclerotized studlike cucullate setae distributed throughout. Their metathoracic tibiae have cucullate setal rows I and II incomplete, row III missing. A key to all species is provided.
