Discosea (Cavalier-Smith et al. 2004) Smirnov et al. 2008 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. Flabellinia Smirnov et al. 2005
Flattened generally fan-shaped, discoid or irregularly triangular, never with pointed subpseudopodia or centrosomes.
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.
