A key is given to the six genera of Signiphoridae including Rozanoviella gen. n. which is described to accommodate five congeneric species, three transferred from Signiphora and two from Thysanus. All are secondary parasites of Hymenoptera and Lepidoptera through Tachinids. The correct name of the type-species of Kerrichiella is shown to be Thysanus coleoptratus Kerrich.
