?vestitum (Deflandre, 1939a, p.189–190, pl.11, figs.4–6) Davey et al., 1966, p.162.  Emendation: Sarjeant, 1960b, p.397, as Baltisphaeridium vestitum.  Holotype: Deflandre, 1939a, pl.11, fig.5; Fauconnier and Masure, 2004, pl.74, figs.11–12.  Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Surculosphaeridium, fourthly (and now) Surculosphaeridium?, fifthly Multiplicisphaeridium? (Appendix A), sixthly SystematophoraStancliffe and Sarjeant (1990, p.207) questionably retained this taxon in Surculosphaeridium.  Questionable assignment: Stover and Evitt (1978, p.83) and Fauconnier and Pourtoy in Fauconnier and Masure (2004, p.518).  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.  Prior to re-examination of the holotype by Fauconnier and Pourtoy, Davey in Kennedy et al. (2000, p.638) indicated that this species should be assigned to Surculosphaeridium without question.  Age: Oxfordian.

Parent: Surculosphaeridium
