Rhogogaster magniserrula Viitasaari, spec. nov. (Figs 4n–p, 5e, f, n, 6p, 7a–q) Material examined. Holotype ♀ (high resolution figures see http://dx.doi.org/10.6084/m9.figshare.1324048). Finland: “ Suomi PP: Simo 12.6.1948, O. Peltonen” (ca. 65.670°N, 25.052°E), coll. SDEI. Paratypes: Finland: 1 ♀ Sipoo, Nevas, 6687:3412, margin of deciduous forest, (ca. 60.285°N, 25.408°E) 14– 20.7.1985, A. Albrecht leg., coll. MV; 1 ♀ EnL, Enontekiö, Pallastunturit, Röyninkuru, (Grid2E) 756:337, 26.7.1951, J. Kaisila leg. (ca. 68.074°N, 24.058°E), coll. MV. This specimen was found on snow and the record was published as “ R. viridis L.”, identified by T. Kontuniemi [Kaisila 1952: 19]. This paper gives a fairly accurate location between Saivokero and Vuontiskero (http://dx.doi.org/10.6084/m9.figshare.1411048). Russia: 1 ♀ “Kirov: Kirov: Vyatka 15–23 July 2001. Sweep-net. Leg. Erik Heibo” (ca. 58.462°N, 49.877°E), coll. E. Heibo (http:// dx.doi.org/10.6084/m9.figshare.1375774). Description. The species is described in the key below. Variability . The holotype and the paratype from Sipoo are very similar to each other, whereas the specimen from Enontekiö is somewhat paler, but all three are clearly darker than the paratype from Russia. The saw of the latter specimen is strongly worn (Fig. 5f). Nevertheless, there is little doubt that these four specimens are conspecific. The specimen from Russia has a much paler abdomen: all terga apically largely green, and the black patches only cover about half of the length of the terga (Fig. 7 n). In contrast, the Finnish specimens have mainly black terga with narrow green apical margins (terga 2–3 medially almost completely black, Fig. 7a). Furthermore, in the Russian specimen the black color on and beside the postocellar area, and on the occiput is clearly reduced (Fig. 7 q). In addition, in the specimen from Kirov, the black line between the mesoscutellum and its appendage is missing (Fig. 7 o), the mesopleural groove is not marked with black, and the femora of the front and middle legs ...
