Jell & Adrain (2003) went so far as to lump Phillipsiidae into the family Proetidae, however other workers since like Lerosey-Aubril and Feist (2005) have continued to recognize Phillipsiidae as a distinct and separate family within Proetida. SubfamiliesThe following genera are included, divided among six subfamilies: {{Div col|colwidth=15em}}
