Genus Angulamoeba Berney, Bass & Geisen, 2015
Diagnosis: Uninucleate, branching naked amoebae with slender, pointed and/or filose-like, sometimes branched pseudopodia. Trophozoites moving too slowly to be seen in light microscopy; main cell body elongated, consisting of up to four main branches often with several smaller lateral branches, never forming a network; numerous fine pseudopodia concentrated mostly at the extremity of the lateral and terminal branches, but can be formed anywhere around the cell body; multiple contractile vacuoles. Movement of entire cells mostly too slow to be directly observable. At least one species with ciliate forms. Floating forms observed in at least one species. Cysts of very regular size and shape, round and relatively small.
Type species: Angulamoeba microcystivorans
