BASIONYM: Eunotia boomsma Furey, Lowe and Johansen 2011

Eunotia bilii

 

Eunotia canicula

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Paula Furey - March 2011
Length Range: 27-45 µm
Width Range: 5.8-6.9 µm
Striae in 10 µm: 12-13 in the center valve

Description

Ventral margin is straight to weakly concave and the dorsal margin is convex and broadly biundulate. Apices are broadly rounded and set off by a change in the slope of the dorsal margin. Helictoglossae are visible in the LM. Raphe with distal ends curved onto the valve surface. Striae are slightly radiate, sometimes with abbreviated striae on the dorsal margin.
