Arturmiles pankowskiarum gen. et sp. nov. (Insecta, Coleoptera, Cantharidae) from Eocene Baltic amber is described and illustrated here. The new taxon, discovered in amber found in Poland, has intermediate characters between the Holarctic realm genera Podistra and Rhagonycha. In addition, some phoretic Acarina are present along the beetle’s body - only the second time phoretic Acarina have been documented on a fossil soldier beetle.
