Korystocysta gochtii
+gochtii (Sarjeant, 1976a, p.11,13, pl.2, fig.1; pl.3, fig.4; text-figs.2A–C) Woollam, 1983, p.194. Holotype: Sarjeant, 1976a, pl.2, fig.1; text-figs.2A–B. Originally Dichadogonyaulax, subsequently Ctenidodinium, thirdly (and now) Korystocysta. Taxonomic senior synonym: Gonyaulax (now Korystocysta) pachyderma, by implication in Conway (1990, p.35), who considered Dichadogonyaulax (as Korystocysta) kettonensis to be the senior name — however, Lentin and Williams (1993, p.374) retained Dichadogonyaulax (as Korystocysta) gochtii. Taxonomic junior synonym: Dichadogonyaulax (subsequently Korystocysta) kettonensis, according to Riley and Fenton (1982, p.199) and Herngreen et al. (2000, p.50). The name Dichadogonyaulax gochtii has priority over the name Dichadogonyaulax kettonensis since the authors who first considered the two species to be synonyms (Riley and Fenton, 1982, p.199) designated the former name as senior (I.C.N. Article 11.5). The nomenclatural type of the genus Korystocysta remains the holotype of Korystocysta kettonensis. Age: Bathonian.
