Aluvarus praeimperialis is an extinct bony fish, known from two headless fossil specimens found in the Elam Formation, a Lower Oligocene stratum from the Rupelian epoch, of what is now Iran. A. praeimperialis was originally thought to be a luvar, described as "Luvarus praeimperialis," as it was thought to be a predecessor to the modern luvar. A later reexamination of the specimens showed that they were too incomplete to demonstrate such a conclusion, and were renamed "Aluvarus," meaning "Not" or "Different than Luvar."
