| Observations: | Bart Van de Vijver |
|---|---|
| Length: | 44-55µm |
| Width: | 8-10µm |
| Striae: | 10-11 striae in 10µm |
Description:
Valves linear with weakly convex margins and obtusely rounded, slightly protracted ends (L 44-55µm, W 8-10µm). Axial area narrow, linear. Central area a broad fascia. Raphe filiform, weakly curved with small, but distinct central pores and large, comma-shaped terminal fissures. Transapical striae radiate in the middle, parallel to moderately convergent near the poles, 10-11 in 10µm. No longitudinal bands present.

Notes:
Baie de La Pérouse, Ile de la Possession, Crozet Archipelago, Sample BM216 (coll. date 28/12/1997).Only found in the vicinity of Baie Lapérouse where it was abundantly present in wet terrestrial moss samples.Only found on Ile de la Possession.Can be confused with P. bottnica Krammer and P. kolbei Manguin but sufficiently differs by its size, more elongate valve outline and the number of striae.
