Gonyaulacysta dictyophora

"dictyophora" Deflandre, 1939a, p.178, pl.8, figs.1–3 ex Sarjeant, 1967b, p.249–250.  Holotype: Deflandre, 1939a, pl.8, fig.1; Jan du Chêne et al., 1986a, pl.7, figs.1–5.  NOW Scriniodinium?.  Originally Palaeoperidinium (name not validly published), subsequently Gonyaulacysta, thirdly Aldorfia, fourthly Scriniodinium, fifthly (and now) Scriniodinium?.  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.

Parent: Gonyaulacysta
