From Fensome et al., 2019:
Cribroperidinium ventriosum (Wetzel, 1933a, p.161–162, pl.2, figs.4–6; text-figs.1,8) Lentin and Williams, 1973, p.35. Emendation: Lejeune-Carpentier and Sarjeant, 1981, p.5, as Cribroperidinium ventriosum. Holotype: Wetzel, 1933a, pl.2, fig.4; Lejeune-Carpentier, 1946, fig.2; Lejeune-Carpentier and Sarjeant, 1981, pl.1, figs.3–4; text-fig.3. Originally Peridinium (Appendix B), subsequently Palaeoperidinium (combination not validly published), thirdly (and now) Cribroperidinium. This combination was not validly published in Sarjeant (1967b, p.257) since that author did not fully reference the basionym. Age: Senonian.
