Class Discosea Cavalier-Smith, 2004 em. Smirnov et al, 2011

 

Diagnosis: Flattened naked amoebae, never producing tubular, subcylindrical pseudopodia and never altering the locomotive form. Cytoplasmic flow polyaxial or without a pronounced axis. No flagellate stage in the life cycle; subpseudopodia, if present, short, never both pointed and branched.

 

 

Subclass Flabellinia Smirnov et al. 2005, em. Smirnov and Cavalier-Smith 2011
