Cleistosphaeridium patagonicum
From Fensome et al., 2019:
Cleistosphaeridium patagonicum Archangelsky, 1969b, p.200–201, pl.3, figs.9–10. Holotype: Archangelsky, 1969b, pl.3, figs.9–10. NOW Impletosphaeridium. Originally Cleistosphaeridium, subsequently Cleistosphaeridium?, thirdly (and now) Impletosphaeridium. Questionable assignment: Stover and Evitt (1978, p.32) as a problematic species. Age:
Eocene.
---------------------------------------------------------------------------------------------------
Original description: [Archangelsky, 1969, p. 200]: (Translation: LPP):
Diagnosis:
Cyst body sphaerical to oval, membrane granulate. Processes of equal length, numerous, irregularly distributed, thin with broad bases, ending in round thickenings or anchor-like, occasionally furcate, straight or wavy. Opening large, ?apical.
Dimensions:
Holotype - 28x28 µm, processes 10 µm.
Range - length 25-31 µm, breadth 17-30 µm, processes 7-12 µm.
