BASIONYM: Encyonopsis subminuta Krammer & Reichardt 1997
LM scalebar = 10 µm = 80 pixels.
Observations
Contributor: Pat Kociolek - March 2011
Length Range: 10-15 µm
Width Range: 3-4 µm
Striae in 10 µm: 23-27
Description
Valves are slightly asymmetrical to the apical axis, with both the dorsal and ventral margins slightly convex. The apices are protracted, relatively narrow and short. The axial area is very narrow, linear. A central area is absent. The raphe is slightly arched, filiform, with external proximal ends dilated slightly. Striae are radiate to nearly parallel.

Valves 10-15 µm long by 3-4 µm wide, slightly asymmetrical to the apical axis. Apices are protracted, relatively narrow and short. The axial area is very narrow and linear and the central area is absent. Striae are radiate to nearly parallel.
Compare
Encyonopsis subminuta is distinguished from E. microcephala by being less strongly asymmetrical to the apical axis and lacking a central area.
