Family Rhogostomidae Dumack, Öztoprak, Rüger and Bonkowski, 2017

Diagnosis: Thecate amoebae with ventral slit-like and not flexible cleft that emits filopodia; theca thin, flexible, in active cells adherent throughout to cell surface, consisting of single smooth dense layer outside and scarcely thicker than the plasma membrane; thus with bilateral symmetry. Theca with exosomes (Capsellina) or without (Rhogostoma, Sacciforma). Omnivorous (mainly bacteria, also yeasts, algae). Electron microscopy of Capsellina and Rhogostoma by Simitzis and Le Goff (1981). Division longitudinal, binary. Sexual reproduction unknown.

Type genus: Rhogostoma Belar, 1921.

Other Genera: Capsellina (Penard 1909; see Howe et al. 2011) Sacciforma (Dumack et al. 2017)
