Leptodinium nannotrix

?nannotrix (Deflandre, 1939b, p.143, pl.6, fig.7) Jan du Chêne et al., 1986a, p.211.  Holotype: Deflandre, 1939b, pl.6, fig.7; Jan du Chêne et al., 1986a, pl.69, figs.4–6.  Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Gonyaulacysta?, fourthly Rhynchodiniopsis?, fifthly (and now) Leptodinium.  Questionable assignment: Jan du Chêne et al. (1986a, p.211) as a problematic species.  Jan du Chêne et al. (1986a, p.211) recommended that this name be restricted to the holotype.  Age: Kimmeridgian.
