Elytrocysta circulata
From Fensome et al., 2019:
Elytrocysta circulata (Clarke and Verdier, 1967, p.67–68, pl.1, fig.11; pl.2, fig.3; text-fig.28) Stover and Helby, 1987d, p.282. Holotype: Clarke and Verdier, 1967, pl.1, fig.11. Originally Dictyopyxidia, subsequently Ellipsoidictyum, thirdly (and now) Elytrocysta. Age: Cenomanian–Santonian.
---------------------------------------------------------------------------------------------------
Original diagnosis (Dictyopyxidia circulata) Clarke and Verdier, 1967, p.68:
A species of Dictyopyxidia with an inner body and outer wall connected by a reticulum; the overall shape is circular.
Original description (Dictyopyxidia circulata) Clarke and Verdier, 1967, p.68:
Inner body and outer wall circular, connected by means of a low reticulum 1-1.5 µm high. The muri are 1.0 µm thick and enclose irregular and polygonal shaped luminae. An elongation of the reticulum parallel to the equator suggests the presence of a girdle in many specimens. Archaeopyle is apical and indented; there are no apical or antapical horns.
Measurements: Length 39-45 µm, breadth 35-40 µm.
