necopinatus" was originally described as ""Proluvarus necopinatus","  citing several anatomical differences between "Proluvarus" and "Luvaris".A later reexamination of the fossil specimens lead researchers to reappraise "Proluvarus" as a junior synonym, as well as determine that specimens of what were originally thought to be juveniles were actually two different species of a different genus of louvar, "Avitoluvarus".
