The genus Eurystylus Stål (Hemiptera: Heteroptera: Miridae: Mirinae) comprises to date 32 species in the world. This group is generally known as phytophagy, and some of the species are known as major insect pests of crops in various regions such as E. oldi Poppius, 1912, reducing grain mass and quality of sorghum crops by feeding and by ovipositing in Africa. Although these species are easily found and widely distributed, there are few taxonomic studies on this group in detail. In Korea, 2 species are known so far: E. coelestialium (Kirkaldy, 1902), E. luteus Hsiao, 1941. In this talk, the genus Eurystylus from the Korean Peninsula is reviewed for the first time. Biological information such as additional host plants of each species, and morphological characters of Eurystylus sp. nov. with other congeners from Korea are presented. Photographs of the Korean specimens, illustrations of the male genitalia, and diagnoses based on main characters with a key to the Korean species are also provided.
