"POLYSTEPHANOSPHAERA" Sarjeant, 1960a, p.140–142. Taxonomic senior synonym: Systematophora, according to Sarjeant (1961b, p.1095–1096). Taxonomic junior synonym: Surculosphaeridium, by implication in Courtinat (1989, p.173), who considered the "type species", Polystephanosphaera valensii to be a taxonomic junior synonym of Hystrichosphaeridium (as and now Surculosphaeridium) vestitum — however, Stancliffe and Sarjeant (1990, p.207–208) retained the two species, as well as the genus Surculosphaeridium. Type: Sarjeant, 1960a, pl.6, fig.4; text-fig.3b, as Polystephanosphaera valensii.
