ABSTRACT. The genus Kostjukovius Graham, 1991 is recorded for the fauna of Russia for the first time. A new species, K. arkharensis sp.n., from the southeast of Amur Province is described and illustrated. The new species is close to K. platycephalae (Kostjukov, 1978) by the scutellum without submedian lines and mid lobe of mesoscutum without median line, but differs from the latter species by the shape of the frontofacial sutures, the shape of pronotum, and by the ratio of the lengths of mid lobe of mesoscutum, scutellum and dorsellum.
KEY WORDS: parasitoids, Tetrastichinae, Kostjukovius, Russian Far East, new species.
