Proetoidea is a superfamily of trilobites in the order Proetida.[1] [2]
The Proetoidea are closely related to the Aulacopleuroidea.[3] and are divided into three families: Phillipsiidae, Proetidae, and Tropidocophyridae.[1]
Phillipsiidae is not listed in some publications (e. g. Adrain, 2011) but is instead listed as a subfamily of the proetidae.[4]
