Gonyaulacysta nannotrix

"?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.
