The Fascinating World of Amoebae
Flabellinia Smirnov et al. 2005
Flattened generally fan-shaped, discoid or irregularly triangular, never with pointed subpseudopodia or centrosomes.

1.0 Dactylopodida Smirnov et al. 2005
Locomotory form as irregular triangle with basement directed forward; wide anterior hyaloplasm; parasomes in Paramoeba and Neoparamoeba; cysts unknown; without fibrous axial cores both in dactylopodia and in the floating pseudopodia.

1.1. Korotnevella Goodkov 1988
Amoeba with finger-like pseudopodia (dactylopodia). The entire amoeba is covered with boat-shaped scales and sometimes micro-scales, too.

Korotnevella sp. (undescribed) with basket-shaped and ellipsoid micro-scales.

1.2. Squamamoeba Kudryavtsev and Pawlowski, 2013
With flattened anterior hyaloplasm producing short conical subpseudopodia from the margin, and on the ventral side, for adhesion to the substratum. Cell coat consisting of scales encloses the entire cell; cytoplasmic projections with the distal parts covered solely by the plasma membrane, may be formed protruding through the scale layer.

This is probably a Squamamoeba sp.

2.0. Vannellida Smirnov et al. 2005
Locomotion as fan-shaped to spatulate cell; without discrete pseudopodia or subpseudopodia; wide anterior hyaloplasm up to half of the cell; posterior granuloplasm concentrated in a “hump”.
