"incerta" (Klumpp, 1953, p.389–390, pl.17, figs.1–2) Morgenroth, 1966a, p.15. Emendations: Morgenroth, 1966a, p.15, as Hystrichosphaera incerta; Sarjeant, 1981, p.109–110, as Spiniferites incertus. Holotype: Klumpp, 1953, pl.17, figs.1–2. NOW Spiniferites. Originally Areoligera, subsequently Hystrichosphaera, thirdly (and now) Spiniferites. Taxonomic junior synonym: Hystrichokibotium (now Spiniferites) pseudofurcatum, according to Morgenroth (1966a, p.15) — however, Sarjeant (1981, p.108–109) retained Hystrichokibotium (as and now Spiniferites) pseudofurcatum. Age: late Eocene.
Parent: Hystrichosphaera
