LM scalebar = 10 µm = 80 pixels.


Contributor: Marina Potapova - February 2013
Length Range: 14-18 µm
Width Range: 3.6-4.5 µm
Striae in 10 µm: 26-28 in the center valve, 30-32 at the ends


Valves are lanceolate with capitate apices. The axial area is linear and narrow. The central area is elliptic, or rectangular. Striae are strongly radiate and bent. Areolae are circular and number approximately 56-64 in 10 µm. The raphe is filiform, with slightly expanded proximal ends. Internally, silica bars are present at the valve apices.

Note that the basionym, Navicula subfasciata Patrick was illegitimate, so the new name, Sellaphora subfasciata, Potapova is a replaced synonym according to the ICBN, Article 58.1.
