            <p> HOSTS. Parasitoid of many species of leaf-mining  Lepidoptera (especially  Phyllonorycter spp. ),  Coleoptera (  Rhynchaenus spp. ), and  Hymenoptera (Tenthredinidae) , as gregarious ectoparasite of their larvae; sometimes as a facultative secondary or tertiary parasite of  Braconidae and Chalcidoidea. </p>
            <p>REMARKS. The Amurian specimen differs from the European ones in having a pedicel relatively shorter, flagellum with sparser and shorter longitudinal sensilla (Figs 4–6); mid lobe of mesoscutum with one row of 3 adnotaular setae on each side (Fig. 7) [European specimens often have 3–4 or more adnotaular setae with a second row of 1–2 setae (Graham, 1987: P. 52–53)]. Also, the Amurian specimen is similar in colour to the European specimens (a very variable in colour), but differs from the later in having the posterior tergites of the gaster yellow, and the third, fourth and fifth tergites with blackish bands (Figs 1–2).</p>

            <p> COMPARATIVE DIAGNOSIS. In addition to the features mentioned in the diagnosis of  A. (O.) kostjukovi sp. n. and the key below,  A. (O.) vasilisae sp. n. is similar to  A. (O.) mycerinus by the scutellum, moderately convex, with submedian lines about equidistant from each other and from sublateral lines, and anterior pair of setae behind the middle of scutellum.  A. (O.) vasilisae sp. n. and  A. (O.) kostjukovi sp. n. are also similar to A. (O.) microocellus Kostjukov, 1995 by the pale yellow base of the gaster, propodeum medially as long as dorsellum, callus with 2 setae and yellow legs. Both new species differ from A. (O.) microocellus in having a longer clava and a shorter female gaster. </p>

            <p>ETYMOLOGY. The new species is named in honour of the world-famous entomologist Francis Walker, who was the first to describe new species of tetrastichine wasps from the Amur River ("Amurland").</p>
