EMENDATION: Sarjeant, 1960b, p.397, as Baltisphaeridium vestitum.

TYPE: Holotype: Deflandre, 1939a, pl.11, fig.5.

HISTORY: Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Surculosphaeridium, fourthly (and now) Surculosphaeridium?, fifthly Multiplicisphaeridium? (Appendix A), sixthly Systematophora. Stancliffe and Sarjeant (1990, p.207) questionably retained this taxon in Surculosphaeridium. Questionable assignment: Stover and Evitt (1978, p.83).

SYNONYM(S): Taxonomic junior synonym: Polystephanosphaera valensii, according to Courtinat (1989, p.173) - however, Stancliffe and Sarjeant (1990, p.209) retained Polystephanosphaera (as and now Systematophora) valensii.
