Interpretive Summary: Leafhoppers and treehoppers transmit plant diseases that cause millions of dollars of damage to agricultural crops every year. In order to predict which species may be new pests, their classification must align with relationships among species. A fairly recent paper of one genus included new species that were misplaced, and other related species were also misplaced. This paper corrects the classification and clarifies the reference species for the group. This information will assist researchers and facilitate agricultural risk assessments of the U.S. Animal and Plant Inspection Service.
Technical Abstract: The similarities and differences in adults and nymphs among three membracine genera are discussed. Sexual dimorphism is shown for Enchenopa monoceros (Germar). Enchenopa varians Walker is reinstated as a valid species. Eight new combinations are proposed: Membracis trinotata (Funkhouser), from Erechtia Walker; Enchenopa minans (Fairmaire), from Campylenchia Stål; and six from Enchenopa Amyot & Serville: Enchophyllum amazonensis (Strümpel and Strümpel), E. grandis (Strümpel and Strümpel), E. longimaculatum (Strümpel and Strümpel), E. pittieri (Strümpel and Strümpel), E. recticornutum (Strümpel and Strümpel), and E. vittiferum (Stål). Three reinstated combinations are proposed: Enchophyllum lanceolatum (Fabricius), E. longicollum (Olivier), and Enchenopa tatei Goding.
