	Rieppel (1998) reassigned "S. buzzii" back to its original combination "Lariosaurus buzzii", together with another lariosaurine genus "Ceresiosaurus". Rieppel (1998) found the two species to form a clade with "Lariosaurus valceresii", while the other species of "Lariosaurus" (incl. the type "L. balsami") formed a second clade, a sister taxon to the first. In 2004, however, this synonymy was objected by Hänni who described and named a second species for "Ceresiosaurus", and by several other authors since.
