Palaeoperidinium "reticulatum" Valensi, 1953, p.28, pl.2, figs.4–5,14,19; pl.13, fig.6; text-fig.2d.

Holotype: Valensi, 1953, pl.2, figs.4–5; Fauconnier and Masure, 2004, pl.28, figs.1–4.

Name not validly published: generic name not validly published until 1967.

NOW Epiplosphaera. Originally Palaeoperidinium (name not validly published), subsequently Dictyopyxis (generic name illegitimate), thirdly Dictyopyxidia, fourthly Ellipsoidictyum, fifthly (and now) Epiplosphaera.

Taxonomic senior synonym: Epiplosphaera bireticulata, by implication in Courtinat (1989, p.176), who believed Palaeoperidinium (as Epiplosphaera) reticulatum to be the senior name — however, Poulsen (1992a, p.66) retained the two species.

Age: Bajocian.
