Description:
Valves elliptical with more or less rounded rostrate ends, L 16-19µm W 6-8,5 µm, transapical striae 16-18 in 10µm in the median part, 25 in 10µm towards the ends. Raphe valve: raphe filiform, axial area lanceolate, central area hemicircular, bordered at one side by 2-4 spaced unilateral striae, open at the other side. ARV: longitudinal linear area. Central area hemicircular, bordered at one side by 4-6 less spaced striae.

Notes:
Fairly common on bare, dry oligotrophic and slightly acid soils. Only a few records (very low abundances) exist from open waterbodies and mosses (mean F-value 3,9±1,2).Widespread in the entire (Sub-)Antarctic Region.
