The tribe Trigonoderini (Hymenoptera: Pteromalidae) contains six genera (Gastracanthus Westwood, Janssoniella Kerrich, Miscogasteriella Girault, Platygerrhus Thomson, Plutothrix Förster and Trigonoderus Westwood). This tribe is recorded from South Korea for the first time. Two new species, Janssoniella albiclava Tselikh & Lee sp. nov. from South Korea and J. magna Tselikh & Lee sp. nov. from South Korea and the South Far East of Russia, are described. Eight species (Gastracanthus acutus (Kamijo), G. nigrescens Kamijo, Janssoniella intermedia Hedqvist, Miscogasteriella sulcate (Kamijo), Plutothrix scrobicula Kamijo, P. trifasciata (Thomson), Trigonoderus fraxini Yang and T. nigrocephalus Kamijo) are recorded from South Korea for the first time. The keys for identification of the Eastern–Palearctic species of Janssoniella and Gastracanthus are given and photos of diagnostic characters of the new species are provided.
