The genera Aphidius Nees, 1818 and Toxares Haliday, 1840 both belong to the subfamily Aphidiinae, a group whose members are obligatory koinobiont endoparasitoids of aphids (Hemiptera, Aphididae). While Toxares is a small genus with only five known species from the Holarctic and Oriental regions, Aphidius is the most diverse within the subfamily with more than 130 recognised species distributed worldwide. Here we describe two new species discovered in the collection of Naturalis Biodiversity Center: Toxares fovealis sp.n. from Europe (the Netherlands) and Aphidius breviflagellaris sp.n. from Eastern Asia (South Korea). We also analyse genetic and morphological variability of Toxares deltiger (Haliday, 1833) specimens collected in Europe and redescribe the species.
