Interpretive Summary: Leafhoppers and treehoppers cause millions of dollars 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 of treehoppers are described in a group previously only with 25 species in the world. Additionally, these unusual new species 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: Three new genera in Acutalini are described, all of which have two discoidal cells (R2+3 and M) in the forewing, as in Euritea Stål. Osaria quadrilinea n. gen. et n. sp. differs from other acutalines in having a pair of suprahumeral spines and a strongly convex pronotum in lateral view. It differs from O. zacki, n. sp., in having an evenly convex, rather than stepwise convex pronotum in lateral view, in addition to other details. Quinquespinosa septamacula n. gen. et n. sp. differs in having three posterior pronotal spines. Tectiforma guayasensis n. gen. et n. sp. has the pronotum strongly tectiform throughout. //add distro gf geera A key to all genera of Acutalini is provided.
