Cleistosphaeridium actinocoronatum
From Fensome et al., 2019:
Cleistosphaeridium actinocoronatum Benedek, 1972, p.34, pl.12, fig.13; text-fig.13. Emendation: Bujak and Matsuoka, 1986, p.238–239, as Reticulatosphaera actinocoronata. Holotype: Benedek, 1972, pl.12, fig.13; Benedek and Sarjeant, 1981, fig.10, no.5; text-fig.11; Sarjeant et al., 1987, pl.2, fig.4; Fensome et al., 1993a, fig.1 — p.879. NOW Reticulatosphaera. Originally Cleistosphaeridium, subsequently Areosphaeridium?, thirdly (and now) Reticulatosphaera. Taxonomic junior synonym: Reticulatosphaera stellata, according to Bujak and Matsuoka (1986, p.238). Age: middle–Late Oligocene.

Original description: [Benedek, 1972, p. 34]: (Translation: LPP):
Diagnosis:
The outer surface of the thin, delicate shell is smooth. The fairly constant number of about 20 processes corresponds to their uniform distribution. Also, the general habit remains uniform, the processes bifurcate into an equidistant outer ring. The bilateral ramifications can further branch widely, and are regularly set with numerous small heels.
Dimensions:
Shell 13/15 µm, processes onto ramifications: 15 (12/17) µm.
