stephanoidea (Colom, 1935, p.12, text-fig.4b) Dufour, 1968, p.1948. Holotype: Colom, 1935, text-fig.4b. Originally Fibrosphaera (Appendix A), subsequently (and now) Stomiosphaera. Dufour did not reference the basionym when proposing this combination, but this was not a requirement since he was using zoological nomenclature. Age: late Early Jurassic.
Parent: Stomiosphaera
