?intermedium Wetzel, 1933b, p.46; text-fig.14 ex Deflandre, 1937b, p.77. Holotype: Wetzel, 1933b, text-fig.14. Originally Hystrichosphaera (name not validly published), subsequently Hystrichosphaeridium, thirdly Baltisphaeridium (Appendix A), fourthly (and now) Hystrichosphaeridium?. Questionable assignment: Stover and Evitt (1978, p.56) as a problematic species. Junior homonym: Hystrichosphaeridium intermedium Eisenack, 1954a. Matsuoka (1983a, p.16) considered Hystrichosphaeridium (as Polysphaeridium) zoharyi to be a possible taxonomic junior synonym of this species. This name was not validly published in Wetzel (1933b) since the generic name Hystrichosphaera was not validly published until 1937. Age: ?Late Cretaceous.
Parent: Hystrichosphaeridium
