Résumé : The skull of Luxilites striolatus, a species of a monospecific genus of fossil teleosts from the marine Upper Cretaceous of Kansas, is studied. The ostcology shows that Luxilites is a valid genus of the order Tselfatiiformes, close to Bananogmius, and that it belongs to a subgroup of Plethodidae comprising, besides Bananogmius, also Syntegmodus and Niobrara.
