The subfamily Acaenitinae Foerster, 1869 is a small-sized group belonging to the family Ichneumonidae. It includes 250 species in 26 genera from Ethiopian, Oriental, and Palaearctic region. However, only 14 species of six genera, Arotes, Coleocentrus, Jezarotes, Phaenolobus, Spilopteron and Yamatarotes have been reported from Korea. This subfamily can be easily recognized from other ichneumonids by the combination of the following characters: subgenital plate very elongate; tarsal claws with accessory tooth. Members of Acaenitinae are parasitoids of wood-boring Coleoptera, Hymenoptera and Lepidoptera. Among them, some of parasitoids of Cerambycidae are known as intermediate carrier of Bursaphelenchus xylophilus (Nematoda: Parasitaphelenchidae). In this study of the Korean Acaenitinae, we found the genus Yezoceryx from Korea for the first time, including newly recorded two species, Y. sp.1 and Y. sp.2. We provide description of the genus and two species with a key to the Korean genera of the subfamily Acaenitinae.
