We describe the giant lytoceratid taxon Lobolytoceras costellatum (PAVIA, 2002) n. comb. from the Upper Jurassic (Oxfordian, “Rauracien”) of SW-Madagascar and discuss the possible relation to the Toarcian (Early Jurassic) species “Lytoceras” siemensi DENCKMANN, 1887 as well as the systematic consequences. The stratigraphic range of the genus Lobolytoceras BUCKMAN, 1923, hitherto only known from the Lower Toarcian will be extended to the Oxfordian-Tithonian (Upper Jurassic).
