Plagiopyxis declivis

Plagiopyxis declivis Bonnet, 1955

Diagnosis: Shell hemispheric, ventral side covered with flat xenosomes, smooth, dorsal side covered with rough xenosomes. Dorsal lip of the shell with a sharp, irregular margin, overhanging; ventral lip projects inside the shell as an elongation of the ventral side, therefore difficult to recognize. Nucleus with several nucleoli.

Dimensions; Diameter 63-79 µm.

Habitat: Soil or xerophile mosses.

Remarks: Scanning electron photomicrographs show that platelets of other testate amoebae (Trinema spp., Corythion spp., Euglypha spp.) are incorporated in the dorsal lip and the ventral side.
