The genus Oberea belongs to the tribe Saperdini (Coleoptera: Cerambycidae) and contains about 270 described species in the world. The genus can be defined by the combination of the following characters: body elongate, cylindrical; legs very short, apex of hind femur not reaching beyond abdominal sternite II. O. vittata Blessig was reconfirmed its distribution in South Korea during the study. Two species are newly reported here: O. heyrovskyi Pic and O. tsuyukii Takashi & Ohbayashi. We provide a revised checklist of 12 species and a pictorial key to species for the identification, with diagnostic characters of O. heyrovskyi and O. tsuyukii.
