Key references
Van de Vijver B. 2022. Two new Staurosirella species (Staurosiraceae, Bacillariophyceae) observed in an historic Rabenhorst sample. Phytotaxa. 545(2): 163-174.
Morphology
Size
5-12 µm long, 3-3.5 µm wide (Van de Vijver 2022).
Shape
Valves elliptic-lanceolate with cuneate to broadly rounded apices.
Symmetry
Isopolar, occasionally slightly heteropolar; bilaterally symmetrical, occasionally slightly asymmetric along the apical axis.
Striae
Striae slightly radiate in valve middle, becoming more strongly radiate towards apices, alternating, 15-16 in 10 µm (Van de Vijver 2022).
Axial area
Narrow, linear.
SEM morphology
Marginal spines in pairs, located on virgae.
