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.
