Gonyaulacysta dictyophora

"Gonyaulacysta dictyophora" Deflandre, 1939a, p.178, pl.8, figs.1-3 ex Sarjeant, 1967b, p.249-250.

TYPE: Holotype: Deflandre, 1939a, pl.8, fig.1; Jan du Chêne et al., 1986a, pl.7, figs.1-5.

HISTORY: NOW: Scriniodinium. Originally Palaeoperidinium (name not validly published), subsequently Gonyaulacysta, thirdly Aldorfia, fourthly (and now) Scriniodinium.

COMMENTS: The name Palaeoperidinium dictyophorum was not validly published in Deflandre (1939a) since the generic name Palaeoperidinium was not validly published until 1967. In validating this name, Sarjeant (1967b, p.249-250) provided an "emended diagnosis".

AGE: Oxfordian.
