Two poorly known Neotropical treehopper genera, Deiroderes Ramos and Holdgatiella Evans, are revised and redescribed based on adult morphology. The Caribbean genus Deiroderes (unplaced within the subfamily Stegaspidinae) has three valid species including D. inornatus, new species (Jamaica). The Neotropical genus Holdgatiella (currently unplaced within Membracidae) has two valid species including H. stria, new species (Venezuela). In addition, a previously unknown Caribbean genus is here described, Togotolania, new genus, with two species: T. longicorna, new species (Dominican Republic) and T. brachycorna, new species (Guadeloupe). All species included in these three genera are illustrated, and keys are given for the identification of adults.
