granulatum ([[Klement, 1960]], p.39-41, pl.4, figs.10-13; text-figs.18-20) [[Stover and Evitt, 1978]], p.150.  Emendation: [[Sarjeant, 1984a]], p.161-162, as Meristaulax granulata.  Holotype: [[Klement, 1960]], pl.4, figs.10-11; text-figs.18-20; [[Fensome et al., 1995]], figs.1-2 - p.1525; disintegrated according to [[Sarjeant, 1984a|Sarjeant (1984a]], p.162).  Lectotype (designated by [[Sarjeant, 1984a]], p.162): [[Sarjeant, 1984a]], pl.3, figs.3-4; text-fig.3; [[Jan du Chêne et al., 1986a]], pl.27, figs.7-10; [[Brenner, 1988]], pl.3, figs.2a-b; [[Fensome et al., 1995]], figs.5-6 - p.1525 - however, [[Brenner, 1988|Brenner (1988]], p.35) argued that this specimen is not conspecific with the holotype.  Lectotype (designated by [[Brenner, 1988]], p.35): [[Brenner, 1988]], pl.1, figs.3a-c; [[Fensome et al., 1995]], figs.7-9 - p.1525.  Originally [[Gonyaulax granulata Appendix B|Gonyaulax]] (Appendix B), subsequently [[Gonyaulacysta granulata|Gonyaulacysta]], thirdly (and now) Cribroperidinium, fourthly [[Rhynchodiniopsis granulata|Rhynchodiniopsis]], fifthly Meristaulax Sarjeant, sixthly [[Acanthaulax granulata|Acanthaulax]].  [[Poulsen, 1996|Poulsen (1996]], p.73) retained this species in Cribroperidinium.  Taxonomic junior synonyms: [[Gonyaulax granuligera Appendix B|Gonyaulax]] (now [[Cribroperidinium granuligerum|Cribroperidinium]]) [[Gonyaulax granuligera Appendix B|granuligera]], according to [[Fisher and Riley, 1980|Fisher and Riley (1980]], p.321) - however, [[Sarjeant, 1984a|Sarjeant (1984a]], p.156-158) retained [[Gonyaulax granuligera Appendix B|Gonyaulax]] (as [[Cryptarchaeodinium granuligerum|Cryptarchaeodinium]]) [[Gonyaulax granuligera Appendix B|granuligera]]; [[Gonyaulacysta angulosa|Gonyaulacysta]] (as [[Acanthaulax angulosa|Acanthaulax]]?, now [[Cribroperidinium angulosum|Cribroperidinium]]) [[Gonyaulacysta angulosa|angulosa]], according to [[Fisher and Riley, 1980|Fisher and Riley (1980]], p.321) - however, Sarjeant and Gocht in [[Sarjeant, 1984a|Sarjeant (1984a]], p.160) retained [[Gonyaulacysta angulosa|Gonyaulacysta]] (as [[Meristaulax angulosa|Meristaulax]]) [[Gonyaulacysta angulosa|angulosa]].  [[Brenner, 1988|Brenner (1988]], p.35) stated that the specimen designated as the lectotype by [[Sarjeant, 1984a|Sarjeant (1984a]], p.102) cannot be a lectotype since it is not from the same sample as the holotype, citing Article 8 of the 1983 I.C.B.N. ([[Voss et al., 1983]]).  The current I.C.B.N. Article 9.9 ([[Greuter et al., 1994]]) implies that a lectotype must be cited in the protologue, not necessarily from the same sample.  Hence, Sarjeant's lectotype cannot be invalidated for that reason.  However, Brenner also argued that the morphology of Sarjeant's lectotype differs sufficiently from that of the holotype to constitute a separate species.  Thus, Brenner proposed a new lectotype from the same sample as Klement's holotype and illustrated it ([[Brenner, 1988]], pl.1, figs.3a-c); this specimen was not figured in [[Klement, 1960|Klement (1960]]).  1994 I.C.B.N. Article 9.13 specifies that the choice of a lectotype by an author may be superseded if it can be shown to be in serious conflict with the protologue.  In contrast to [[Lentin and Williams, 1993|Lentin and Williams (1993]], p.2), [[Williams et al., 1998|Williams et al. (1998]], p.148) followed [[Brenner, 1988|Brenner (1988]]).  See also discussion under Meristaulax granulata (Klement).  [[Helenes, 1984|Helenes (1984]], p.116) considered [[Gonyaulax venusta Appendix B|Gonyaulax]] (now [[Cribroperidinium venustum|Cribroperidinium]]) [[Gonyaulax venusta Appendix B|venusta]] to be a possible taxonomic junior synonym of this species.  Age: Mid Oxfordian-Early Kimmeridgian.
