Hystrichogonyaulax cladophora subsp. cladophora

"subsp. cladophora".  Autonym.  Holotype: Deflandre, 1939a, pl.7, fig.1; Jan du Chêne et al., 1986a, pl.94, fig.6.  NOW Rhynchodiniopsis cladophora subsp. cladophora.  Originally Gonyaulax cladophora subsp. cladophora (Appendix B), subsequently Gonyaulacysta cladophora subsp. cladophora, thirdly Hystrichogonyaulax cladophora subsp. cladophora, fourthly (and now) Rhynchodiniopsis cladophora subsp. cladophora.  Taxonomic junior synonyms: Gonyaulax (as Rhynchodiniopsis) cladophora subsp. extensa, Gonyaulax (as Rhynchodiniopsis) cladophora subsp. hemipolyedrica and Gonyaulax (as Rhynchodiniopsis) cladophora subsp. isovalvata, all by implication in Brenner (1988, p.72), who listed these subspecies as taxonomic junior synonyms of Rhynchodiniopsis cladophora - however, Lentin and Williams (1993, p.566) retained all three taxa.
