LM scalebar = 10 µm = 80 pixels.


Contributor: Ian Bishop - December 2015
Length Range: 12-16 µm
Width Range: 3.6-3.8 µm
Striae in 10 µm: 17-18


Valves are small and rhombic to rhombic-lanceolate, with rounded apices. Striae are weakly radiate at mid-valve, becoming parallel, even weakly convergent near the apices. The axial area is narrow and the raphe is filiform. The central area is bow tie-shaped with two shortened striae, one on either side. A distinct hyaline area is found at both apices. Areolae are not visible in LM.
