Description:

Valves linear to linear-elliptical with obtusely rounded, slightly subrostrate ends (L 21-28µm, W 4-6µm, 14-17 striae in 10µm). Axial area narrow, linear. Central area rhomboid, forming a broad, usually symmetrical fascia. Raphe filiform with laterally bent small central pores and ?-shaped terminal fissures, not always resolvable in LM. Transapical striae radiate in the middle, more parallel to convergent towards the poles. No longitudinal lines present.

Morphology: Naviculoid

Notes:

Only found in very low abundances (total of 13 valves) in several soil samples. Therefore a clear view on the ecological preferences is not possible.Kerguelen (Bourrelly & Manguin 1954, Le Cohu & Maillard 1996), South Georgia (Van de Vijver & Beyens 1996, 1997a).
