Axial area relatively large, widening from the poles towards the middle of the valve. Central area a rectangular fascia. Raphe filiform, curved with distinct central pores.

Notes:
Only present in one soil sample, taken from a shallow cave in the vicinity of Pointe Basse. The accompanying diatom flora points to increased salinity input (it is possible that the cave is used as a shelter by marine birds).So far only found on Ile de la Possession but since this is a recently established taxon (Lange-Bertalot & Genkal 1999), records may be included within similar taxa.
