Hystrichosphaeridium truncigerum Deflandre, 1937
Now Raetiaedinium. Originally Hystrichosphaeridium, subsequently Litosphaeridium?, thirdly Cordosphaeridium, fourthly Exochosphaeridium, fifthly Pervosphaeridium, sixthly Tityrosphaeridium?, seventhly Florentinia, eighthly Pervosphaeridium?, ninethly (and now) Raetiaedinium.
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 synonym - 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).
Davey and Williams, 1969, transferred this species to Litosphaeridium Davey and Williams 1966. Lentin and Williams, 1973, retained it in Hystrichosphaeridium Deflandre 1937.
Holotype: Deflandre, 1937, pl.13 [al. pl.10], fig.6
