The family Cicadellidae (Hemiptera: Auchenorrhyncha) is one of the largest insect families, and contains approximately 22,000 described species. All members of this group are phytophagous, therefore, many of them are known as insect pests. Additionally, some species can transfer some pathogens such as viruses and phytoplasmas to plants as a vector. Macropsis (Cicadellidae: Macropsinae) is one of the largest groups in Cicadellidae, and has a world distribution. Among them, M. mendax and M. fuscula are famous for a vector associated with phytoplasma disease in Europe (Elm yellow, Rubus stunt disease). In Korea, three Macropsis species have been recorded to date. In this talk, genus Macropsis is reviewed from Korea. Morphological information such as diagnoses and descriptions of genitalia and the key to Macropsis are presented.
