Description

Valves are broadly elliptic with rounded, sometimes slightly protracted apices. The raphe valve is concave and the rapheless valve is convex. The raphe valve has a narrow, straight axial area, widening towards a rhomboid central area. The raphe is straight with simple ends. Terminal raphe fissures are absent. The axial area of the rapheless valve is broad, rhomboid, with a horseshoe depression on one side that extends to the valve margin. Striae are biseriate and radiate.

Autecology Discussion

Platessa strelnikovae has been so far found in sediments of three lakes in Vermont and Maine. These lakes are soft-water, circumneutral and mesotrophic.
