Genus Palaeoperidinium

Palaeoperidinium Deflandre, 1934, p.968 ex Sarjeant, 1967b, p.246-247.

SYNONYM(S): Taxonomic junior synonyms: Astrocysta, Morkallacysta and Pentagonum, all according to Lentin and Williams (1976, p.150,160,161) - however, Stover and Evitt (1978, p.113-114) retained Morkallacysta.

COMMENTS: This name was not validly published in Deflandre (1934) since that author did not designate a type, which he was obliged to do since he was using zoological nomenclature (I.C.Z.N. Article 13b). No type was designated until Sarjeant (1967b) did so, and who also brought the generic name under the auspices of the I.C.B.N. This interpretation differs from previous editions of this index and accords with that of Loeblich Jr. and Loeblich III (1966) and, in essence, also that of Sarjeant (1967b). In contrast to the contention of Tappan and Loeblich Jr. (1967, p.526), Deflandre (1934, p.968) did publish a description of Palaeoperidinium, as a footnote.

TYPE: Ehrenberg, 1838, pl.1, fig.4, as Peridinium pyrophorum.
