Chavan & Fischer (1939) suggested that this species may be the descendant of the Upper Oligocene Volutithes anomalus Schlotheim, 1820. As a matter of fact, that taxon is often be considered to be a chrono-subspecies of the taxon under discussion. It is here considered to be the precursor of the species under discussion.
