"Cleistosphaeridium? oligacanthum" (W. Wetzel, 1952, p.402-405, pl.A, figs.4,7-8,11a-b; text-figs.21-25) Davey et al., 1969, p.16.
EMENDATION: Wilson and Sarjeant in Sarjeant, 1984c, p.128, as Laticavodinium oligacanthum. TYPE: Holotype: W. Wetzel, 1952, pl.A, fig.8; Sarjeant, 1984c, pl.2, figs.4-5; text-fig.2; Fensome et al., 1995, figs.1-5 - p.1625. HISTORY: NOW: Impletosphaeridium. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Cleistosphaeridium?, fourthly Laticavodinium, fifthly (and now) Impletosphaeridium?. Stover and Williams (1987, p.146) retained this species in Cleistosphaeridium. Questionable assignment: Davey et al. (1969, p.16). COMMENTS: This combination was not validly published in Davey et al. (1966, p.170), since these authors did not fully reference the basionym. AGE: Danian.
