Gonyaulax cladophora subsp. isovalvata Appendix B

"subsp. isovalvata" Klement, 1960, p.37–38, pl.4, figs.5–9; text-fig.17.  Holotype: Klement, 1960, pl.4, figs.5–6.  NOW Rhynchodiniopsis cladophora subsp. isovalvata.  Originally Gonyaulax cladophora subsp. isovalvata, 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 Rhynchodiniopsis cladophora — however, Lentin and Williams (1993, p.566) retained Gonyaulax (as Rhynchodiniopsis) cladophora subsp. isovalvata.  Age: early Kimmeridgian.
