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.
