Naming

In German the common name is "Dunkler Braunwurzschaber" (dark figworts scraper), which highlights the species preference for "Braunwurzgewächse" (the figwort family Scrophulariaceae) or "Braunwurzen" (figworts, the genus Scrophularia). The prefix "dark" distinguishes it from the "Weißschildiger Braunwurzschaber" (white-shielded figworts scraper), the Cionus scrophulariae (figwort weevil).
