Description:
Valves linear with parallel margins and cuneately rounded ends (L 37-84µm, W 10-13µm, L/W ratio 5,4-6,3, 10-11 striae in 10µm). Axial area narrow, acute towards the ends (±1/4 of valve width). Central area rhomboid to elliptical, asymmetrical. Raphe moderately lateral with laterally bent drop-like central pores, relatively close together. Terminal fissures 'viridis'-like (Krammer (2000). Transapical striae slightly radiate in the middle, parallel to convergent towards the apices. A narrow longitudinal band is present and well resolvable in LM.

Notes:
Rare taxon, although present in all habitat types. Prefers very wet (>80%) acid soils, wet mosses and circumneutral to slightly alkaline pools and lakes, with high specific conductance values (>1000µS/cm).First record from the Subantarctic Region.Previously reported from Ile de la Possession as P. rupestris Hantzsch (Van de Vijver & Beyens 1998b, 1999a&b). Recently established taxon (based on a variety of P. rupestris).
