Phillipsiidae is sometimes defined as a subfamily, "Phillipsiinae," and usually placed within the family Proetidae. 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.
