A new species of Oruza Walker, 1861 (Lepidoptera, Erebidae, Boletobiinae) from Korea with barcode-based pairing

A new species of the genus Oruza, O. koreana sp. nov. is described, based on 14 specimens collected in Korea. The species is closely related to Oruza obliquaria Marumo, 1932 but can be distinguished from the latter by the shapes of the costal process in the male genitalia and the lamella postvaginalis in the female genitalia. The occurrence of Oruza obliquaria in Korea is discussed. Two COI barcodes of O. koreana sp. nov. are provided to facilitate pairing and reliable identification.
