Cavalier-Smith et al. 2004 sensu Smirnov et al. 2011
Flattened naked amoebae, never producing tubular, subcylindrical pseudopodia and never altering the locomotive form to the tubular, subcylindrical one; cytoplasmic flow polyaxial or without a pronounced axis; ciliated stages unknown; several taxa sporocarpic.
Smirnov et al. 2005
Generally fan-shaped, oblong or irregularly triangular cells, never with pointed subpseudopodia.
Schaeffer 1926 sensu Smirnov et al. 2011
Oblong, lingulate, or irregularly triangular amoebae, usually with dorsal folds and/or ridges; anterior hyaloplasm often forms an antero-lateral crescent and rarely occupies more than half of the body length; never produces discrete pseudopodia or subpseudopodia.
Schaeffer 1926, emend. Cavalier-Smith 2004
Oblong, flattened cell with dorsal folds and/or ridges; anterior hyaloplasm forms antero-lateral crescent and never occupies half or more of the body length; cell coat relatively thin, amorphous or with extra structures based on amorphous layer.

Oblong, lancet-shaped or irregularly triangular in locomotion; with smooth cell surface or with few wide ridges, never wrinkled; short, wide triangular pseudopodia and in some genera subpseudopodia of dactylopodial type; thick cell coat, multilayered or consisting of tightly packed helical structures.

Locomotive form mostly has a shape of an irregular triangle with basement directed forward; wide anterior hyaloplasm; fibrous axial cores both in dactylopodia and in the floating pseudopodia.

Locomotive form fan-shaped to spatulate; cells do not form discrete pseudopodia or subpseudopodia; wide anterior hyaloplasm up to a half of the cell; posterior granuloplasm concentrated in a “hump”, often raised over the substratum; one species of Vannella (V. fimicola) with protosteloid sporocarps.

MTOC located near the dictyosome; several taxa with protosteloid sporocarpy. Pointed subpseudopodia common.
Page 1976
Flattened with prominent subpseudopodia, flexible and tapering to a fine tip and sometimes furcated near their base (acanthopodia); without adhesive uroid, some species in culture appear as a branched, flattened sheet. At least two taxa, Acanthamoeba and Luapeleamoeba, contain species with protosteloid sporocarpy.

Dorsal surface covered with a flexible coat (tectum) without a defined aperture; ventral surface entirely or partly naked; can form ventral flattened sheet of hyaloplasm used for adhesion to the substratum.
