Description:
Valves broad-elliptical (L 10-12µm, W 6-7µm). ARV: axial area narrow, somewhat lower than the rest of the valve. Transapical striae strongly radiate, 20-26 in 10µm, consisting of 4-5 slit-like areolae, clearly visible in LM. Areolae are on the outside sometimes covered with half-lunar-shaped vela. RV: small, but in LM still visible valvocopula boards the entire valve, forming a hyaline margin. Axial area narrow, linear with a straight, filiform raphe. Central pores clearly visible, quite close together. Transapical striae 22-26 in 10µm, radiate, consisting of one row of rounded areolae.

Notes:
This taxon has only been found in the region around Lapérouse where several valves (only minor abundances : 5-10%) were observed in semi-wet mosses and in a small lake with circumneutral pH and high conductivity values (1730µS/cm).First record from the (Sub-)Antarctic Region.
