Pachyphloiidae is a family of uniserial Permian Foraminifera included in the fusulinid superfamily Geinitzinacea along with the Geinitzinidae. Three genera are recognized. They are:
Pachyphloia, type
Robustopachyphloia,
Maichelina
Pachyphloiid genera are characterized by their free, compressed, uniserial tests with broad low chambers recurved laterally and microgranular calcareous walls with secondary lamellar thickening on both sides which distinguishes them from the ancestral Geinitzinidae.
