Cotesia Cameron is a cosmopolitan genus of the subfamily Microgastrinae. This genus comprises more than hundreds of species (Whitfield et al., 2009). The members of the genus Cotesia parasites on larvae of Macrolepidoptera: Noctuidae, Geometridae and Saturniidae (Achterberg & Polaszek, 1996; Whitfield et al., 2009). Previously, 33 Korean species of the genus have been investigated by several researchers (Kim, 1963; 1970; Ku et al., 2001; Papp, 1974; 1990; 2003). In this study, Cotesia urabae is reported for the first time from Korea. Diagnosis, distribution, and host information are provided.
