Cymatiosphaera membranacea Philippot 1949 Appendix A

"membranacea" (Philippot, 1949, p.57-58; text-fig.3) Davey and Williams in Davey et al., 1969 (December), p.5.  Holotype: Philippot, 1949, text-fig.3.  Name illegitimate - senior homonym: Cymatiosphaera membranacea (Deunff, 1955 ex Deunff, 1961b) Stockmans and Willière, 1969 (April).  Substitute name: Cymatiosphaera philippotii (Appendix A).  Originally Hystrichosphaeridium membranaceum, subsequently Cymatiosphaera membranacea (name illegitimate), thirdly (and now) Cymatiosphaera philippotii (Appendix A).  Junior homonym: Cymatiosphaera membranacea Kiryanov, 1974, a prasinophyte species.  This combination was not validly published in Davey and Williams (1966b, p.104), since these authors did not fully reference the basionym.  Age: Late Cretaceous.
