"Luvarus necopinatus" is a species of extinct louvar that lived in the Tethys Ocean during the early Paleogene. It differs from the modern species, "L. imperialis", in that "L. necopinatus" has an oval body shape, and is around one foot in length when fully grown.

The first specimens were found from the Danata Formation Lagerstätten, of the Thanetian to Ypresian epochs of Turkmenistan. "L. necopinatus" was originally described as "Proluvarus necopinatus"," [ [http://si-pddr.si.edu/dspace/bitstream/10088/5708/2/SCtZ-0485-Lo_res.pdf] Morphology of "Luvarus imperialis" (Luvaridae), with a Phylogenetic Analysis of the Acanthuroidei (Pisces)] citing several anatomical differences between "Proluvarus" and "Luvarus". 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" [ [http://www.sil.si.edu/smithsoniancontributions/Paleobiology/pdf_lo/SCtP-0081.pdf] Phylogenetic Revision of the Fish Families Luvaridae and †Kushlukiidae (Acanthuroidei), with a New Genus and Two New Species of Eocene Luvarids] .
