The family Nabidae (Hemiptera: Heteroptera: Cimicomorpha) is a cosmopolitan family of medium-sized (4-12 mm.) predatory groups in true bugs. Among them, 10 genera and approximately 130 species are distributed in the Palaearctic region. Most Nabidae are predators on various stages of insects (e.g., aphids, leafhoppers and lepidopteran eggs and young caterpillars), but several genera within the subfamily Prostemmatinae (e.g., Prostemma, Alloeorhynchus and Pagasa) are specialized predators of true bugs, especially of the family Lygaeidae. Most Nabinae are herbicolous and arboricolous, whereas all Prostemmatinae are ground-inhabiting (in litter layer, under stones, etc.). In this talk the family Nabidae is reviewed from Korea including two unrecorded species and one new species. The morphological information such as description and diagnoses, and biological information for each species are provided.
