The subfamily Metopiinae is a cosmopolitan group comprising 836 species within 26 genera. Among them, 275 species have been recorded from the Eastern Palaearctic region (Yu et al., 2012). Hypsicera, is easily distinguished from other genera by the absence of an areolet and the back of its head dropping vertically from the hind margin of the lateral ocelli to the foramen magnum. Most species of this genus are koinobiont endoparasitoids of lepidopteran larvae, such as Gelechiidae, Pyralidae and Tortricidae. Sometimes they attack the larvae of Hymenoptera, after which they always emerge from the pupa (Townes, 1971).

Hypsicera is a cosmopolitan group that was reported with 63 species, 17 of which have been recorded from the Eastern Palaearctic region. Among the fauna of South Korea, only six species have been reported by Cha et al. (2000) and Tolkanitz (2007). During this study we reviewed seven unrecorded species, H. bicolor, H. brevicornis, H. incarinata, H. intermedia, H. postfucalis, H. spiracularis and H. yoshimoboi, from South Korea. Among them H. incarinata and H. yoshimoboi are also new to China. Here we report seven unrecorded species from South Korea with the diagnoses and photographs and females of H. brevicornis and H. nigribasis with new description. Also we provide a key to 13 South Korean species.

The images of the specimens were taken using an Axio Cam MRc5 camera attached to a stereo microscope (Zeiss SteREO Discovery, V20; Carl Zeiss, Göttingen, Germany), processed using AxioVision SE64 software (Carl Zeiss), and optimized with a Delta imaging system (i-solution, IMT i-Solution Inc. Vancouver, Canada). The morphological terminology mostly follows that of Townes (1969).
