Dictyopyxis reticulata Valensi, 1953, p.28, pl.2, figs.4–5,14,19; pl.13, fig.6; text-fig.2d ex Sarjeant, 1968, p.230.

NOW Epiplosphaera. Originally Palaeoperidinium (name not validly published), subsequently Dictyopyxis (generic name illegitimate), thirdly Dictyopyxidia, fourthly Ellipsoidictyum, fifthly (and now) Epiplosphaera.
The name Palaeoperidinium reticulatum was not validly published in Valensi (1953) since the generic name Palaeoperidinium was not validly published until 1967. Following I.C.N. Article 55.1, the species name Dictyopyxis reticulata is validly published even though the generic name Dictyopyxis is illegitimate.
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.
