Rhynchodiniopsis cladophora subsp. isovalvata
subsp. isovalvata (Klement, 1960, p.37–38, pl.4, figs.5–9; text-fig.17) Below, 1981a, p.118. Holotype: Klement, 1960, pl.4, figs.5–6. Originally Gonyaulax cladophora subsp. isovalvata (Appendix B), subsequently Gonyaulacysta cladophora subsp. isovalvata, thirdly Hystrichogonyaulax cladophora subsp. isovalvata, fourthly (and now) Rhynchodiniopsis cladophora subsp. isovalvata. Taxonomic senior synonym: Gonyaulax (as Rhynchodiniopsis) cladophora subsp. cladophora, by implication in Brenner (1988, p.72), who listed this subspecies as a taxonomic junior synonym of the species Rhynchodiniopsis cladophora — however, Lentin and Williams (1993, p.566) retained Gonyaulax (as Rhynchodiniopsis) cladophora subsp. isovalvata. Age: early Kimmeridgian.
