Cordosphaeridium truncigerum

"truncigerum" (Deflandre, 1937b, p.71–72, pl.13 (al. pl.10), figs.6–7) de Coninck, 1975, p.80.  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.  Taxonomic senior synonym: Xanthidium (now Hystrichokolpoma) crassipes, by implication in Yun Hyesu (1981, p.27), who considered Cordosphaeridium (as Pervosphaeridium) truncigerum to be the senior name — however, Lentin and Williams (1985, p.282) retained Cordosphaeridium (as Pervosphaeridium) truncigerum.  Taxonomic junior synonym: Laticavodinium latispinosum (name not validly published), according to Slimani (2001a, p.194).  Age: Senonian.
