Dictyopyxidia reticulata
Dictyopyxidia reticulata (Valensi, 1953) Lentin and Williams, 1973
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.
Holotype: Valensi, 1953, pl.2, figs.4-5; Fauconnier and Masure, 2004, pl.28, figs.1-4.
Age: Bajocian
