Wetzeliella rotundata
From Fensome et al., 2019:
Wetzeliella "rotundata" Balteş, 1969, p.35, pl.5, fig.10.
Name not validly published: provisional designation.
NOW Rhombodinium. Originally Wetzeliella (name not validly published), subsequently (and now) Rhombodinium.
Taxonomic junior synonym (at specific rank): Rhombodinium draco forma freienwaldense (as Rhombodinium freienwaldense), by implication in Costa and Downie (1979, p.44), who believed Rhombodinium freienwaldense to be the senior name — however, Grabowska in Malinowskiej and Piwockiego (1996, p.343) retained Rhombodinium freienwaldense.
Holotype: Balteş, 1969, pl.5, fig.10
Age: Oligocene.
---------------------------------------------------------------------------------------------------
Original description (Balteş, 1969) Translation PKB 2024
Cyst with rhomboidal appearance, total length 140-160 microns, width 120-126 microns. Apical horns and notably the lateral ones considerably rounded. Antapical horn however molding two light prominences. No process. Finely granulated smooth gold outer membrane. Endophragm with an ovoid outline occupying almost the entire interior cavity. Age and locality: Oligocene marls and sands of the Precarpathian Depression, Rm. Vilcea (Muiereasca) area
