polyedrica (Pouchet, 1883, p.42, fig.34) Jörgensen, 1900, p.33.  Holotype: Pouchet, 1883, fig.34.  Originally Peridinium (Appendix B), subsequently (and now) Goniodoma, thirdly HeteraulacacystaLentin and Williams (1973, p.67–68) retained this species in Goniodoma, restricting it to modern forms.  Morgenroth (1966a, p.7) included Eocene fossils in this modern, motile-based species.  Lentin and Williams (1973, p.67–68) proposed Heteraulacacysta fehmarnensis for fossil cysts which resemble Goniodoma polyedrica.  Age: extant.
