Ellipsoidictyum reticulatum

"reticulatum" (Valensi, 1953, p.28, pl.2, figs.4–5,14,19; pl.13, fig.6; text-fig.2d ex Sarjeant, 1968, p.230) Lentin and Williams, 1977b, p.56.  Holotype: Valensi, 1953, pl.2, figs.4–5; Fauconnier and Masure, 2004, pl.28, figs.1–4.  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.  Sarjeant (1978a, p.18) also proposed this combination.  Age: Bajocian.
