Proetidae is a family of proetid trilobites. The first species appeared in the Upper Ordovician,[1] and the last genera survived until the Middle Permian. However, if the closely related family Phillipsiidae is actually a subfamily of Proetidae, then the proetids of Proetidae survive until the end of the Permian, where the last perish during the Permian–Triassic extinction event.[2]
Genera[]
Proetidae ostensibly contains these following genera, though many may be placed in Phillipsiidae if the latter is, indeed, a distinct family.[3]

- Endops
- (syn=Capricornia[4])
- Eocyphinium
- Gerastos
- Gitarra
- Hedstroemia
- Helokybe
- Malchi
- Mezzaluna
