Taxonomy:

Citation: Pappomonas weddellensis Thomsen in Thomsen et al., 1988
Rank: Species

Distinguishing features: Central area with axial cross
CFC process ca. 2.0-2.5 µm high, with short stem supporting two large fan-like blades, one markedly larger than the other.
AACs have much reduced symmetrical central processes without a shaft and smaller distal appendages and may have baseplate calcification of 8 radial bars instead of 4.
