Actinotheca aphroditae
From Fensome et al., 2019:
Actinotheca aphroditae, Cookson and Eisenack, 1960a, p.9, pl.2, figs.19–20.
Holotype: Cookson and Eisenack, 1960a, pl.2, fig.20; Helby et al., 1987, fig.39H.
Age: Turonian.
Locus typicus: Carnarvon Basin, Australia
Stratum typicum: Turonian

Original description: [Cookson and Eisenack, 1960, p. 9-10]:
Description:
Shell roughly circular in outline, consisting of a flat, somewhat hexagonal, box-like body and a broad transparent two-layered wing. The wing is supported by a series of fibres, consisting of five pairs of evenly spaced fibres that run radially to the circumference of the wing, where they join and form loops; two sets of fibres that are connected with the radial fibres and run tangentially slightly within the outer edges of the anterior and posterior surfaces of the body, where they form a hexagonal pattern; and a group of three or four pairs of fibres that form a cluster or loose tangle of loops on one side (probably ventral) of the shell. There is some evidence that the body of the shell opens by the detachment of a circular position of the anterior wall.
Dimensions:
Holotype: diameter of shell 85 µm; diameter of body 42 µm.
Range: diameter of shell 80-120 µm.
