N. bohemica, 113 µm long – Ordesa, Pyrenees, Spain 2018

 

Nebela bohemica  Taranek, 1882

Diagnosis: Test resembling N. collaris, pyriform, slightly yellowish or brownish, laterally compressed with small lateral pores (number of pores can vary), which can be difficult to observe. The test can be composed mainly oval or circular test plates or can be composed only of organic cement. Neck very short or almost absent, with relatively large aperture which is without thickened edge and curved or truncated right.

Dimensions: Length: Taranek 85-125 µm, width 61-105 µm, aperture 31-40 µm wide.

Ecology: in Sphagnum swamps, mosses, aquatic vegetation in peaty bogs.

Remarks: This species belongs to the Nebela collaris-bohemica complex and is hard to distinguish from N. collaris. Maybe it’s the same species.
