Genus Surculosphaeridium

Surculosphaeridium Davey et al., 1966, p.160-161.

EMENDATION: Davey, 1982b, p.15 - however, see Stancliffe and Sarjeant (1990, p.207).

SYNONYM(S): Taxonomic senior synonym: Polystephanosphaera, 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.2, as Hystrichosphaeridium cribrotubiferum.
