Gonyaulacysta nannotrix
From dinoflaj2
"?nannotrix" (Deflandre, 1939b, p.143, pl.6, fig.7) Sarjeant, 1969, p.10. Holotype: Deflandre, 1939b, pl.6, fig.7; Jan du Chêne et al., 1986a, pl.69, figs.4-6. NOW Leptodinium. Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Gonyaulacysta?, fourthly Rhynchodiniopsis?, fifthly (and now) Leptodinium. Questionable assignment: Stover and Evitt (1978, p.159) as a problematic species. This combination was not validly published in Sarjeant (1966b, p.132), since that author did not fully reference the basionym. Age: Kimmeridgian.
