From Fensome et al., 2019:
Dinogymnium denticulatum (Alberti, 1961, p.5, pl.3, figs.2–3) Evitt et al., 1967, p.18. Holotype: Alberti, 1961, pl.3, fig.2. Originally Gymnodinium (Appendix B), subsequently (and now) Dinogymnium. Herngreen (1975, p.63) implied that Dinogymnium undulosum is a possible taxonomic junior synonym of this species. Boltenhagen (1977, p.73) also proposed this combination. Age: Senonian.
