Gonyaulacysta apionis

"apionis" (Cookson and Eisenack, 1958, p.36, pl.3, fig.7; text-figs.3–4) Sarjeant, 1969, p.8.  Holotype: Cookson and Eisenack, 1958, text-figs.3–4; Jan du Chêne et al., 1986a, pl.33, fig.6.  NOW Cribroperidinium.  Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Millioudodinium, fourthly (and now) Cribroperidinium.  Taxonomic senior synonym: Gonyaulax (now Cribroperidinium) edwardsii, according to Burger (1980a, p.82) — however, Jan du Chêne et al. (1986a, p.76) retained Gonyaulacysta (as Cribroperidinium) apione.  This combination was not validly published in Sarjeant (1966b, p.130), since that author did not fully reference the basionym.  Age: Albian.

Parent: Gonyaulacysta
