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). Age: Senonian.
