The Banchinae are a large cosmopolitan subfamily that includes approximately 1,800 species in 67 genera. The number of species in South Korea is still pooly known and only 18 of the 312 Eastern Palaearctic species have been reported (Yu et al., 2016). Most species are koinobiont endoparasitoids of lepidopteran larvae and pupae. Teleutaea is a moderately sized genus, comprises 20 described species from Palaearctic, Neotropic and Oriental regions. One species has been described from Mexico. The data of the species from the neighbor countries was summarized as follow: 10 species from Russia (Kuslitzky, 2007); 10 species from Japan (Momoi, 1978; Watanabe & Maeto 2014); 15 species from China continental (Sheng, 2014); three species from Taiwan (Chiu, 1965). Until now the genus was not known from South Korea. Members of this genus parasitize on lepidopterous larvae and pupae living in different kinds of hideaways after than, they emerge from the pupa as adult. As a result, we newly recorded seven species from South Korea including a new species. The key for identification of the South Korean species of Teleutaea and description of a new species are provided.
