Peteinosphaeridium hymenoferum Appendix A
From dinoflaj2
hymenoferum (Eisenack, 1938a, p.19, pl.3, figs.2-5) Fensome et al., 1990, p.390. Holotype: Eisenack, 1938a, pl.3, fig.2. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly (and now) Peteinosphaeridium. This combination was not validly published in Eisenack (1969a, p.254), since that author did not fully reference the basionym. Age: Ordovician (erratic).
Parent: Peteinosphaeridium
