B e m e r k u n g: Diese Art ist über die gesamte Holarktis verbreitet. Die nordamerikanischen Stücke sind durchschnittlich grösser als Eu. iripennis und Eu. suteri und dunkler gefärbt ( Abb. 8 View Abb ). Die Bestimmung ist in manchen Fällen unsicher (z. B. bei Exemplaren aus Ottawa und solchen aus hohen Lagen der Berge in NH: die Flügeldeckengrösse scheint mit zunehmender Höhe z. B. auf dem Mt. Washington abzunehmen); vgl. dazu auch oben.
