zoharyi (Rossignol, 1962, p.132, pl.2, fig.10) Bujak et al., 1980, p.34.  Holotype: Rossignol, 1962, pl.2, fig.10.  Originally Hystrichosphaeridium, subsequently Polysphaeridium? (combination not validly published), thirdly Hemicystodinium, fourthly (and now) Polysphaeridium.  Taxonomic junior synonyms: Polysphaeridium subtile, according to Islam (1983b, p.343) - however, Lentin and Williams (1989, p.300) retained Polysphaeridium subtile; Tenua (as Hemicystodinium?) taugourdeaui, according to Lentin and Williams (1981, p.27,127) - however, Tenua taugourdeaui is now considered a taxonomic junior synonym of Polysphaeridium subtile; Membranilarnacia delicata, according to Jain and Garg (1991, p.82).  Motile equivalent: Pyrodinium bahamense Plate, 1906, according to Wall and Dale (1969, p.140); Pyrodinium bahamense var. compressum (Böhm, 1931) Steidinger et al., 1980, according to Matsuoka (1989, p.220).  Matsuoka (1983a, p.16) considered Hystrichosphaera (as Hystrichosphaeridium) intermedia to be the possible taxonomic senior synonym of this species.  This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.95), since these authors did not fully reference the basionym.  Age: Pleistocene.
