The subfamily Pimplinae currently include 1,737 worldwide species in 77 genera. 57 species in 18 genera have been recorded from South Korea. Among them, the genus Scambus is a moderate sized group in the subfamily Pimplinae with 152 described species from Nearctic, Neotropical, Oriental and Palaearctic regions. The taxonomic study of the South Korean Scambus was initiated by Uchida (1928), who reported one species, Scambus calobatus (Gravenhorst, 1829). The genus Tromatobia is small group in this subfamily with 33 species from Afrotropical, Austrian, Nearctic, Neotropical, Oriental and Palaearctic regions. This genus was newly recorded from South Korea for the first time. In this study, we report seven unrecorded South Korean species, Scambus nigricans (Thomson, 1877), Scambus vesicarius (Ratzeburg, 1844), Tromatobia flavistellata Uchida & Momoi, 1957, Tromatobia nipponica Uchida, 1928, Tromatobia ornata (Gravenhorst, 1829), Tromatobia ovivora (Boheman, 1821) and Tromatobia variabilis (Holmgren, 1856).
