The genus Apolygus China (Hemiptera: Heteroptera: Miridae), comprising 64 species in the world, is one of the most diverse groups in the subfamily Mirinae, including well-known insect pests such as A. spinolae and A. lucorum. A total of 56 species are known in the Palaearctic Region up to date, and most of them have been described from China (28 species), Japan (26 species) and Russia (13 species) respectively. In this talk, taxonomic study on the genus Apolygus from the Korean Peninsula is presented with three Apolygus sp. nov. and two newly recorded species. Photographs and illustrations of diagnostic characters and biological information such as host plants and distributions for each species, and a key to the Korean species are provided. Besides, COI barcoding as a diagnostic tool for this group is discussed emphasizing on the low genetic distances between some species.
