Euphydryas aurinia (Rottemburg, 1775) banghaasi Seitz, 1908.
An example of an unclear taxonomical situation. In South Siberia, from Altai to Baikal, this species is represented by two forms: the typical inhabiting low altitudes and a peculiar f. banghaasi Seitz, 1908, which differs from the former by paler colour and substantially smaller size and is confined to highlands, inhabiting mostly marchy dwarf-birch thickets at 1600-2800 m above sea level. No intermediates are found, as well as the habitats of the forms are fully separated. An analogous form merope exists in the Alps. Higgins wrote he would ascribe the apline forms a species rank if there were any difference in the genitalia existing. Some authors, however, considered banghaasi as a distinct species (Lukhtanov, Lukhtanov, 1994).
Range of the species: S Europe, S Ural and S Transuralia, the mountains of S Siberia east to Kentei Mts., E Kazakhstan and Mongolia; the Prilenskoe Plateau; Ural and Yakutia rare.
