Raphe filiform with slightly depressed central pores. Terminal pores simple, ending next to or just after the last transapical striae. T-shaped endings lacking. Foramina of the transapical striae only slightly elongated, in the middle small and rounded.

Notes:

Very common on Ile de la Possession in soils and drier moss vegetation. It is probably one of the most common terrestrial diatoms on the island. It has a preference for relatively dry, acid soils (moisture content <40%) with variable nutrient and salinity conditions.So far only found on Ile de la Possession
