Family Rhizaspididae Skuja, 1948

Thecate amoebae with ventral cleft that emits fine pseudopodia, which anastomose as reticulopodia in one species; theca thin, flexible, laterally compressed, adherent throughout to cell surface, consisting of single smooth dense layer outside and scarcely thicker than the plasma membrane; thus with bilateral symmetry, unlike other filose testate amoebae, which are typically radially symmetric.

Known genera:

Rhizaspis
