"echinoides" (Maier, 1959, p.318–319, pl.32, figs.5–6) Davey et al., 1969, p.15. Holotype: Maier, 1959, pl.32, fig.6. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Cleistosphaeridium. Taxonomic senior synonym: Xanthidium (as Spiniferites) ramosum, according to Sarjeant (1983, p.91–92). This combination was not validly published in Davey et al. (1966, p.170), since these authors did not fully reference the basionym. Age: middle Oligocene–middle Miocene.
Parent: Cleistosphaeridium
