Litosphaeridium crassipes
"?crassipes" (Reade, 1839, pl.9, figs.2-5) Davey and Williams, 1969, p.5. Emendation: Lejeune-Carpentier and Sarjeant, 1981, p.10, as Hystrichokolpoma? crassipes. Holotype: Reade, 1839, pl.9, fig.2, lost according to Lejeune-Carpentier and Sarjeant (1981, p.11). Neotype: Lejeune-Carpentier, 1941, fig.9; Lejeune-Carpentier and Sarjeant, 1981, pl.3, fig.3; text-fig.6; designated by Lejeune-Carpentier and Sarjeant (1981, p.11). NOW Hystrichokolpoma. Originally Xanthidium (Appendix A), subsequently Hystrichosphaeridium, thirdly Litosphaeridium?, fourthly (and now) Hystrichokolpoma. Questionable assignment: Davey and Williams (1969, p.5). Taxonomic junior synonym: Hystrichosphaeridium (as Pervosphaeridium) truncigerum, by implication in Yun Hyesu (1981, p.27), who considered Hystrichosphaeridium (as Pervosphaeridium) truncigerum to be the senior name - however, Lentin and Williams (1985, p.282) retained Pervosphaeridium truncigerum. This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.83), since these authors did not fully reference the basionym. Age: Late Cretaceous.
