Dilatisphaera williereae Appendix A

williereae (Martin, 1966a, p.389-391, pl.1, fig.23; text-figs.33-34) Le Hérissé, 1989, p.115.  Holotype: Martin, 1966a, pl.1, fig.23.  Originally Hystrichosphaeridium, subsequently Dilatisphaera (combination not validly published), thirdly Palaeohystrichosphaeridium (Appendix A), fourthly (and now) Dilatisphaera.  Taxonomic junior synonym: Ozotobrachion? podolicus Sheshegova, 1973, an acritarch species, according to Kiryanov (1978, p.90).  This combination was not validly published in Lister (1970, p.65) since that author did not clearly use the name Dilatisphaera williereae.  Age: Silurian.
