Description

[Only one isolated plate scale was observed.] Scale circular, 0.47 µm diameter, with a marginal ring of 14 perforations and a blunt central spine 0.52 µm long.

Distribution

Southern Ocean, south of Australia.

Comments

The scale seen by us is similar to the freshwater P. circumforaminifera Wujek, a species with scales 0.4–0.55 µm diameter, patterned with a single marginal ring of 18–22 perforations, and with a blunt central spine 0.7–0.9 µm long. Our material is also reminiscent of P. oligocycla which has 2–4 concentric rings of perforations.
