Discosea (Cavalier-Smith et al. 2004) Smirnov et al. 2011 Flattened naked amoebae that never produce tubular, subcylindrial pseudopodia and never alter their locomotive form. Cytoplasmic flow polyaxial or without a pronounced axis. Subpseudopodia short or absent.
1. Centramoebia Cavalier-Smith et al. 2016 Centrosomes present.

Dorsal surface covered with rigid coat without defined aperture; ventral surface naked.
Cell coat envelops the entire cell and is integrated with the cell membrane. For locomotion and phagocytosis amoebae produce short subpseudopodia protruding through the cell coat and covered at the distal end solely by the cell membrane.
