Litosphaeridium truncigerum

"?truncigerum" (Deflandre, 1937b, p.71-72, pl.13 [al. pl.10], figs.6-7) Davey and Williams, 1969, p.6.  Holotype: Deflandre, 1937b, pl.13 (al. pl.10), fig.6.  NOW Raetiaedinium.  Originally Hystrichosphaeridium, subsequently Litosphaeridium?, thirdly Cordosphaeridium, fourthly Exochosphaeridium, fifthly Pervosphaeridium, sixthly Tityrosphaeridium?, seventhly Florentinia, eighthly Pervosphaeridium?, ninthly (and now) Raetiaedinium.  Questionable assignment: Davey and Williams (1969, p.6).  Taxonomic senior synonym: Xanthidium (now Hystrichokolpoma) crassipes, 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 Hystrichosphaeridium (as Pervosphaeridium) truncigerum.  Taxonomic junior synonym: Laticavodinium latispinosum (name not validly published), according to Slimani (2001a, p.194).  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: Senonian.
