Tineobius Ashmead, 1896 is a relatively small group in the family Eupelmidae. It can be distinguished by the following characters: head with conspicuously lengthened maxillary palpus, mesotibia without apical groove, gaster with deeply emarginate syntergum and filiform ovipositor sheaths. Most species of Tineobius were recorded from Afrotropical, Australasian and Oriental region. However, in Palearctic region, only one species (Tineobius tamaricis Ribes & Fusu) is discovered from Spain by Fusu & Ribes (2017). In this study, the genus Tineobius is reported from South Korea for the first time, with two newly recorded species. Also, a key to South Korean species of Tienobius, diagnoses and photographs of the diagnostic characteristics are provided.
