B e m e r k u n g e n: Eu. iripennis CASEY , Eu. laeviusculus MANNERHEIM und Eu. suteri nov.sp. bilden einen Komplex sehr nah verwandter Arten, ihre Aedoeagen sind sich zum Verwechseln ähnlich. Eu. laeviusculus ist die grösste der drei Arten, ihr Medianlobus ist vorn abgerundet, während bei den anderen beiden, kleineren Arten, der Medianlobus vorn eine spitze Gestalt zeigt (vgl. Abb. 11 -25). Zu weiteren Unterschieden s. bei S. suteri.
