Distribution. Finland.—Westpalearctic: northern and central Europe ( Linsenmaier 1959).

Remarks. The species is only known from a few localities in western Finland, where it occurs in warm sandy habitats, often close to the coast. It has been classified as vulnerable in Finland ( Paukkunen 2010). Trautmann (1927, 1930) reported the species from southern Sweden, and later also Balthasar (1954), Noskiewicz & Pulawski (1958), Móczár (1967) and Banaszak (1980) mentioned the species from the country. We have considered these records as doubtful, as we have not seen any Swedish specimens in collections. The closest known records outside Finland are from Poland ( Banaszak 1980), Belarus ( Shljachtenok 2006) and northern Germany ( Jakobs & Kornmilch 2007).
