Chytroeisphaeridia simplicia

"simplicia" Wall, 1965b, p.308; text-figs.7,20.  Holotype: Wall, 1965b, text-figs.7,20; Eisenack and Kjellström, 1972, p.187; Fensome et al., 1995, fig.1 - p.1785.  Name not validly published: no Latin diagnosis.  NOW Brigantedinium.  Originally Chytroeisphaeridia simplicia (name not validly published), subsequently (and now) Brigantedinium simplex.  Motile equivalent: Protoperidinium conicoides (Paulsen, 1905) Balech, 1974, according to Harland (1981, p.68).  This name was not validly published in Wall (1965b), since that author did not provide a Latin diagnosis, a requirement since this species is based on living material (I.C.B.N. Article 36.1).  Age: extant.
