Paragocevia placopus
Paragocevia placopus, 75 µm broad

Paragocevia placopus (Hülsmann, 1974)

Diagnosis: Locomotive form flattened, often remaining flattened when stationary; flattened hyaloplasmic margin surrounding slightly raised granuloplasm anteriorly and laterally, rarely posteriorly; subpseudopodia c. 5-10 µm long, often more than 100 on hyaloplasmic margin in locomotion; protoplast filling cuticle completely; granuloplasm sometimes more rounded up in stationary forms; seldom any conical pseudopodia on floating cells; nucleus with large central nucleolus; ingest diatoms, bits of filamentous algae and blue-greens, ciliate protozoa; no cyst known.

Dimensions: 62-125 µm (mean 95 µm), L/B 0.6-1.0 (mean 0.8), nucleus 12.4-15.0 µm (mean 14 µm). My measurements 75 µm broad, nucleus 12.3 µm (n=1)

Ecology: Freshwater. I found this species once in the Spiegelplas.
