Genus Micropyxidiella

Testate amoebae with filamentous pseudopodia, entirely organic shell (without self-secreted scales or mineral particles). Shell is ovoid, transparent and comparable to the related species of Ovulinata parva. Shell with a pointed end, reminding of certain members of genus Difflugia such as D. acuminata, clearly visible under scanning electron microscopy, but not under light microscopy. Aperture is terminal, slit-like. Large round nucleus (about 20 % of shell length). Ecology: soil. Monospecific. Type species: Micropyxidiella edaphonis Tarnawski et Lara, 2015.
