Dactylopodida Smirnov et al., 2005, sensu Kang et al. 2017

Diagnosis: 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.
Parasomes in Paramoeba and Neoparamoeba; cysts unknown; without fibrous axial cores both in dactylopodia and in the floating pseudopodia; cortex with extracellular scales, pentagonal or hexagonal glycostyles or a complex fibrous ‘cuticle’.

Remarks: The name “dactylopodida” refers to the finger-shaped pseudopodia, also called dactylopodia, which are common for this taxon, see the image below.

Incertae sedis: Boveella, Dactylosphaerium, Oscillosignum, Podostoma, Striolatus, Subulamoeba,Trienamoeba.
