Neolioceratoides is a genus of ammonites that lived during the Pliensbachian and Toarcian stages of the Early Jurassic. It has been considered to be a synonym of Lioceratoides,M. K. Howarth 2013. Treatise on Invertebrate Paleontology, Part L, Revised, Volume 3B, Chapter 4: Psiloceratoidea, Eoderoceratoidea, Hildoceratoidea.Schlegelmilch, R. (2014). Die Ammoniten des süddeutschen Lias: ein Bestimmungsbuch für Fossiliensammler und Geologen. Springer-Verlag. although cladistic analysis has shown that this genus is not only valid, but they even belong to different subfamilies, as Lioceratoides belongs to Harpoceratinae.Bardin, J., Rouget, I., & Cecca, F. (2016). The phylogeny of Hildoceratidae (Cephalopoda, Ammonitida) resolved by an integrated coding scheme of the conch. Cladistics. Its fossils were found in Europe and northern Africa.Fauré, P., ALMéRAS, Y., Sekatni, N., & Zargouni, F. (2007). Le Pliensbachien de Jebel Zaghouan (Tunisie). Nouvelles données fauniques.

Description
Ammonites belonging to this genus have evolute, moderately compressed shells. Whorl section is subtrapezoidal to subrectangular. Ventrum is tricarinate, but furrows are not very deep. Ribs are present even on living chamber and have sigmoidal shape. It differs from Lioceratoides by being more evolute and having thicker whorl section. Ribs are also are more regularly arranged.
