Compare Encyonopsis montana
Encyonopsis cesatii and E. cesatii var. geitleri have smaller, narrowly lanceolate valves and less strongly radiate striae near the apices. Encyonopsis stafsholtii is smaller and has long attenuated apices and a distinctly notched central area on the ventral side. Encyonopsis treinishii has a central stigma. Encyonopsis cesatiformis has smaller lanceolate valves and less strongly radiate striae near the apices. Cymbopleura lapponica has wider valves, a larger central area, proximal raphe ends that are deflected ventrally and terminal raphe fissures that are curved toward the dorsal margin.
