Six new species, Bracon (Bracon) kimchanghyoi sp. nov., B. (B.) yeogisanensis sp. nov., B. (Habrobracon) allevatus sp. nov., B. (Osculobracon) perspicillatus sp. nov., Syntomernus flavus sp. nov., and S. scabrosus sp. nov. are described from South Korea and short keys for their identification are presented. The genus Ficobracon van Achterberg & Weiblen, 2000, syn. nov. is considered a junior synonym of Syntomernus Enderlein, 1920 and new combinations are proposed for Syntomernus asphondyliae (Watanabe, 1940), comb. nov., S. brusi (van Achterberg & Weiblen, 2000), comb. nov., S. codonatus (Huang & van Achterberg, 2013), comb. nov., S. kashmirensis (Maqbool, Akbar & Wachkoo, 2018), comb. nov., S. rhiknosus (Huang & van Achterberg, 2013), comb. nov., S. sunosei (Maeto, 1991), comb. nov. (= Bracon flaccus Papp, 1996, syn. nov.), and S. tamabae (Maeto, 1991), comb. nov.
