Gonyaulacysta pachyderma

"Gonyaulacysta pachyderma" (Deflandre, 1939a, p.176-178, pl.7, figs.6-10; text-figs.7-10) Sarjeant, 1969, p.10.

TYPE: Holotype: Deflandre, 1939a, pl.7, figs.6-7.

HISTORY: NOW: Korystocysta. Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Ctenidodinium, fourthly Ctenidodinium?, fifthly (and now) Korystocysta, sixthly Dichadogonyaulax.

SYNONYM(S): Taxonomic junior synonyms: Leptodinium norrisii, according to Benson (1985, p.154); Dichadogonyaulax (now Korystocysta) kettonensis, by implication in Conway (1990, p.35), who considered Dichadogonyaulax kettonensis to be the senior name - however, Lentin and Williams (1993, p.374) retained Dichadogonyaulax (as Korystocysta) kettonensis.

COMMENTS: This combination was not validly published in Sarjeant (1966b, p.131), since that author did not fully reference the basionym.

AGE: Oxfordian.
