Difflugia stechlinensis var. arctica , from Schönborn, 1966

Difflugia stechlinensis var. arctica  Schönborn, 1966

Diagnosis: Test with almost parallel sides, dorsally broadly arched. Test in cross-section and pseudostome circular, hyaline, completely covered with quartz pieces.
The variety differs only in size from the type.

Dimensions: Length 55-63 μm.

Ecology: Freshwater. Type and variety often appeared together in the sediments of the lakes. So far, D. stechlinensis has only been found in oligotrophic lakes. Interesting is their appearance in the tundra above the tree line.
