Pseudocucurbitella is a genus of freshwater testate amoebae of the order Arcellinida. Its shell is agglutinated, ovoid, with a round crossection and a circular aperture surrounded by 3 to 5 separate lobes forming a short collar.^[2]

Originally, it was described as a subgenus of Difflugia in 1960, but was elevated to genus level in 1972. The taxonomic position of Pseudocucurbitella among Arcellinida is uncertain^[2] and the genus has been abandoned by recent classifications,^[3] but it was initially assigned to the family Difflugiidae.^[1]
