Description:
Valves elliptical-lanceolate with rostate to subcapitate ends (L 12-20µm, W 5 7µm, 19-22 striae in 10µm). Axial area narrow, linear. Central area symmetrical, wedge-shaped due to 4-6 regularly shortened striae. Raphe filiform, slightly arcuate with distinct terminal and central pores. No terminal fissures. Transapical striae radiate to parallel near the pores. Areolae rounded, placed in double rows in 'quincunx'-position.

Notes:
Quite common in wet moss samples and freshwater habitats (both standing and running water), usually in circumneutral, nutrient-poor conditions with low conductivity values.Kerguelen (Germain 1937, Bourrelly & Manguin 1954, Larson 1974, Le Cohu 1981, Le Cohu & Maillard 1986, Van de Vijver et al. 1998a, 2001), Macquarie Island (McBride et al. 1999).Recently created genus by Lange-Bertalot to accommodate 4 taxa, clearly distinct from Navicula s.s.
