Mariusz Kanturski, Yerim Lee, Jinyeong Choi, and Seunghwan Lee (2018) This study reports the first record of the oak-feeding aphid species Lachnus chosoni Szelegiewicz, 1975 (Hemiptera: Aphididae: Lachninae) in the Republic of Korea. Until now, only apterous viviparous females from the type material and type locality-Myohyangsan Mountain (The Democratic People’s Republic of Korea)-were recorded. Apterous viviparous females of L. chosoni were collected from Quercus sp. in the area of Soul National University in Seoul for the first time in 2016. The specimens, which were collected in October and November 2017, represent the sexual generation of this species. We describe and figure the hitherto unknown oviparous female and apterous male of L. chosoni for the first time in detail. Notes on biology and copulation are also provided.

Key words: Aphid, Biodiversity, Lachnini, Morph, Quercus, Sexuales.
