Chalcididae Latreille, 1817 currently include 1,464 extant species in 87 genera in the world. This family is probably easy to define taxonomically. Body robust with coarse puncture, prepectus extremely narrow, hind femur typically swollen and on inner margin with one or more teeth. Members of this family are primary endoparasitoids on pupa of Diptera and Lepidoptera. Up to date, only 12 species of 6 genera belonging to three subfamilies have been recorded from South Korea. As a result of this study, six species (Chalcis sp. 1, Conura sp. 1, Haltichella cf. nipponensis Habu, Hockeria cf. bifasciata Walker, Proconura sp. 1 and Steninvreia cf. petiolata Bouček) in Chalcididae are recorded for the first time in South Korea. Among them four genera (Haltichella Spinola, Hockeria Walker, Proconura Dodd and Steninvreia Bouček) are recorded for the first time in South Korea. Therefore, 18 species of 10 genera in Chalcididae are recorded from South Korea.
