neptuni (Eisenack, 1958a, p.399, pl.26, figs.7–8; text-fig.8) Davey and Williams, 1966a, p.51–52. Emendations: Duxbury, 1983, p.55, as Spiniferites neptuni; Sarjeant, 1985a, p.89–90,92, as Florentinia? neptuni. Holotype: Eisenack, 1958a, pl.26. fig.7. Originally Baltisphaeridium (Appendix A), subsequently (and now) Achomosphaera, thirdly Achomosphaera?, fourthly Spiniferites, fifthly Florentinia?. Questionable assignment: Stover and Evitt (1978, p.139) — however, Lister and Batten (1988b, p.31–32) retained this species in Achomosphaera without question. Since the epithet is based on a familiar name with an existing Latin genitive, it ends in "i" rather than "ii" (I.C.N. Recommendation 60C.2). Age: Early Cretaceous.
