Rolfina arnei gen. nov. et sp. nov. is a common benthic species in the Upper Oligocene/Lower Miocene of the North Sea region. The species has a regional biostratigraphical significance, but has hitherto been designated by open nomenclature as “Rotalia” sp. 1 or Glabratella? sp. A by authors working in the North Sea basin. The genus Rolfina is hereby erected and the species Rolfina arnei is described and illustrated. The species seems to be restricted to the North Sea basin between latitudes of 55°N and 59°N in an outer neritic to upper bathyal paleoenvironment, probably at restricted oxygen levels.
