Family Microchlamyiidae Ogden, 1985
Diagnosis: Lobose testate amoebae with flexible shell composed of granular chitinoid elements (areoles), pseudostome pliable and variable.
Diagnosis: Cell enclosed within a membranous sac which is fixed to the shell at intervals, but lost in empty shells. This membrane closes the shell from the ventral side and forms an aperture for the lobopodia.
Diagnosis: Cell not enclosed within a membrane, but the ventral side is closed by a membrane, which forms an aperture for the lobopodia.
