Soc. imp. Nat. Moscou 1837 (1): 10 Originally published as “ Argynnis selenis “ Type locality after Eversmann: “Kasan.” Three male syntypes were found in ZISP . All specimens are very similar, have the same style of preparation and definitely belong to the same series. The species is widely distributed especially in Siberia and Far East with many described infraspecies taxa, thus, to preserve the stability of zoological nomenclature, it is important to have the name-bearing type of the taxon fixed by a lectotype designation . Lectotype ( Figs 16–18 ): male, forewing length 20 mm , with three original labels: - printed label "coll. Acad. Petrop."; - small square gold label (typical mark of the type in those times); - rectangular label with very special dark reddish irregular color (typical for some old types ) “Russ. Mer.” [ Russia meridionalis] . The specimen is in good condition, only some scales are lost from the costal sides of both forewings. We added the red label: “ LECTOTYPUS / Argynnis selenis / Eversmann, 1837 / S. CHURKIN et al. des.“ Paralectotype 1 ( Figs 19–21 ): male, forewing length 19 mm , with two original labels: - printed label "к. Ершова." [Erschoff’s collection]. - rectangular orange-red label with (typical for some old types ) “Kasan” [Kazan]. The specimen is in good condition, but both antennae are situated above the head and wings so that both are inconspicuous. Figures 16−21 . Clossiana selenis Eversmann, 1837 , adult specimens and labels: 16. C. selenis , lectotype, male, upperside (ZISP); 17. C. selenis , lectotype, male, underside (ZISP); 18. C. selenis , lectotype, labels; 19. C. selenis , paralectotype, male, upperside (ZISP); 20. C. selenis , paralectotype, male, underside (ZISP); 21. C. selenis , paralectotype, labels. We added the red label: “ PARALECTOTYPUS / Argynnis selenis / Eversmann, 1837 / S.CHURKIN et all. des.“ Paralectotype 2 (not figured on the plate): male, forewing length 18 mm , with two original labels: - printed label "к. Ершова." [Erschoff’s collection]. - rectangular label with dark reddish irregular colour “Kasan” [Kazan] (the piece of the paper seems to be the same as the label under the lectotype ). The specimen is in good condition, but has no head. We added the red label: “ PARALECTOTYPUS / Argynnis selenis / Eversmann, 1837 / S.CHURKIN et al. des.“ Type locality: vicinity of Kazan, Tatarstan , Russia . Status . Clossiana selenis is bona species, widely distributed in Siberia and Far East, but with very limited known area in Europe (European part of Russia ) where the nominate taxon is known to occur.
