The North Korean sawflies housed in the Hymenoptera Collection of the Hungarian Natural History Museum are studied, with a focus on the subfamilies Athaliinae and Allantinae. Five genera and ten species of the two subfamilies are identified. Athalia indiana Benson is reported for the first time from East Asia (North Korea), and further eight species and one subspecies are discovered in the new country of North Korea: Allantus helanshanicus Wei, Li and Xiao, Apethymus kolthoffi (Forsius), A. sidorenkoi Sundukov, Athalia japonica (Klug), A. proxima (Klug), A. rosae ruficornis Jakowlew, Beleses satonis (Takeuchi), Taxonus carbonarius Takeuchi, and T. montanus Togashi. Additionally, Athalia infumata (Marlatt) syn. nov. is considered a junior subjective synonym of A. proxima (Klug). Diagnoses and photographs of the newly recorded species are provided, as well as new distributional records and brief notes on the new synonymy.
