Description:
Valves elliptical with rostrate apices (L 18-25µm, W 7-9µm, 14-17 striae in 10µm, consisting of 3-4 rows of areolae). RV: axial area lanceolate, no central area present. Apical raphe terminals curve both to the same side of the valve. Central striae much shorter. ARV: very narrow axial area. Striae parallel in the middle, slightly radiate towards the apices.

Autecology:
Notes:
Rarely found in pools and lakes with variable pH (6,3-8,8) and specific conductance (80-1830µS/cm). No observations were made in moss samples while in soils only a few valves were found.Kerguelen (Le Cohu & Maillard 1983), South Orkney Islands (Jones et al. 1993), South Shetland Islands (Kawecka & Olech 1993, Kawecka et al. 1998), Antarctic Continent (Robert& & McMinn 1996), Macquarie Island (McBride et al. 1999).
