Material examined. Denmark: LFM: Bavnehøj v. Vålse, 11.VIII.1916, 1 ex. (L. Jørgensen); SZ: Gjorslev, 20.VIII.1917, 1 ex. (L Jørgensen) .

Distribution. Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden, Russian Fennoscandia.—Transpalearctic: from West Europe to Siberia, Manchuria and Russian Far East ( Linsenmaier 1959, Kurzenko & Lelej 2007).

Remarks. The species has been recorded from all Nordic and Baltic countries, and it can be relatively abundant in warm sandy areas, where its crabronid host Astata boops occurs. In Norway it is rare and classified as near threatened ( Hansen et al. 2010), and in Denmark only two individuals have been collected, in the southern part of the country (see data above).
