First records of the genera Aclitus and Protaphidius (Hymenoptera, Braconidae, Aphidiinae) from South Korea

The aphidiine genera Aclitus Förster, 1863 and Protaphidius Ashmead, 1900 (Hymenoptera, Braconidae, Aphidiinae) each contain only a few species worldwide. In this study, we report the first records of Aclitus and Protaphidius from Korea, based on specimens of Aclitus sappaphis Takada & Shiga, 1974 and Protaphidius nawaii (Ashmead, 1906). We provide detailed morphological characters, diagnostic characters, and photographic documentation for both species. A new host record, Hamamelistes betulinus (de Horváth, 1896), of Aclitus sappaphis is provided. To support species identification and future phylogenetic studies, mitochondrial ( COI , COII , ND1 , Cytb ) and nuclear ( 28SD2 , EF1A1 , Wingless ) gene sequences for both species are also provided.
