Paragocevia
Paragocevia
Paragocevia, 75 µm broad

Genus Paragocevia Page, 1987

Diagnosis: Discoid cell around 100 µm in length with a flattened hyaline margin and slightly raised granular mass. Frequently with numerous small (5 to 10 µm) conical subpseudopodia from the margin. Cuticle without microscales or foreign particles.

Ecology: Freshwater habitats.

Remarks: Formally this genus is like Gocevia except in the occurence of many short, digitate subpseudopodia on the flattened hyaline margin in locomotion. Its cuticle somewhat resembling that of G. fonbrunei in fine structure. However, the one described species is commonly flattened and more regular in shape than the species of Gocevia.
Paragocevia bears some light microscopic resemblance to species classified as Hyalodiscus.
The cuticle is observed with difficulty on living amoebae. It can often be seen with differential interference contrast on flattened but non-living cells, extending micrometres beyond the hyaloplasm. It is also distinguishable around the hump of somewhat rounded cells fixed for light microscopy (Page, 1988).
