'''''Aluvarus praeimperialis''''' is an extinct ray-finned fish, known from two headless larval fossil specimens found in the Pabdeh Formation, a Late Eocene stratum from the Priabonian epoch, of what is now Iran.<ref name=":0" /><ref name=":1">{{Cite journal |last1=Bannikov |first1=A.

The Pabdeh Formation was originally dated to the early Oligocene, but more recent analysis indicates it to be from the mid-late Eocene, most likely the Priabonian. It inhabited an open ocean habitat with a significant deepwater component to the fauna.<ref name=":1" /><ref name=":2" />
