Gonyaulacysta diaphana

"diaphana" (Cookson and Eisenack, 1958, p.36, pl.3, figs.13–14; text-figs.10–11) Sarjeant, 1969, p.9.  Holotype: Cookson and Eisenack, 1958, pl.3, figs.13–14; text-figs.10–11; Jan du Chêne et al., 1986a, pl.32, fig.6.  Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Cribroperidinium.  Taxonomic senior synonym: Gonyaulax (now Cribroperidinium) muderongense, according to Backhouse (1988, p.80).  This combination was not validly published in Sarjeant (1966b, p.130), since that author did not fully reference the basionym.  Age: Aptian.
