Coronifera oceanica ssp. magna (W. Wetzel, 1955) emend. Sarjeant, 1984
Originally Hystrichosphaeridium pseudhystrichodinium ssp. magnum, subsequently Baltisphaeridium pseudhystrichodinium ssp. magnum, thirdly (and now) Coronifera oceanica ssp. magna, fourthly Coronifera pedata ssp. magna.
Sarjeant, 1985, transferred this taxon to Coronifera pedata (O. Wetzel, 1933) Sarjeant, 1985. Lentin and Williams, 1989, retained it as a subspecies of Coronifera oceanica Cookson and Eisenack, 1958.
