Gymnodinium albertii Vozzhennikova, 1967; Emendation: Lentin and Vozzhennikova, 1990, p.23, as Dinogymnium vozzhennikovae.
Now Dinogymnium vozzhennikovae. Originally Gymnodinium albertii, subsequently (and now) Dinogymnium vozzhennikovae.
Holotype: Vozzhennikova, 1967, pl.5, fig.7; Lentin and Vozzhennikova, 1990, pl.3, figs.2-3; text-fig.9
Locus typicus: Smolensk region, Roslavl"sk district, Volokonschina, Russia
Stratum typicum: Turonian
Translation Vozzhennikova, 1967: Lentin and Vozzhennikova, 1990
Original description: Vozzhennikova, 1967, p.41-42
Theca broadly elliptical, divided by a shallow, wide furrow into two almost equal parts. Epitheca and hypotheca broadly rounded at the poles. Sliqhtly raised ribs run from the transverse furrow towards the poles; these ribs are situated at varying distances from each other. The position of the longitudinal furrow is indlstinct, possibly because it is difficult to discern among the ribs. The theca is thin, pale yellow in color, smooth or finely granular, covered with ribs.
