Discolithus incohatus Stover, 1966
Eiffellithus cretaceus arkhangelskyi Reinhardt, 1965
Prediscosphaera arkhangelskyi (Reinhardt, 1965) Perch-Nielsen, 1984
ICN states in Art. 11.2. “A name has no priority outside the rank in which it is published (but see Art. 53.4)”. Therefore, the species Discolithus incohatus Stover, 1966, has priority over the subspecies Eiffellithus cretaceus arkhangelskyi Reinhardt, 1965, because it was published before the latter subspecies was amended into species rank.
