xanthiopyxides (Wetzel, 1933b, p.44-45, pl.4, fig.25 ex Deflandre, 1937b, p.77) Stover and Evitt, 1978, p.85. Emendations: Morgenroth, 1968, p.556, as Hystrichosphaeridium? xanthiopyxides; Sarjeant, 1985b, p.142-144, as Tanyosphaeridium xanthiopyxides. Holotype: Wetzel, 1933b, pl.4, fig.25, Morgenroth, 1968, pl.48, fig.5; Sarjeant, 1985b, pl.3, figs.2-3; Dietz et al., 1999, fig.10, no.8. Originally Hystrichosphaera (name not validly published), subsequently Hystrichosphaeridium, thirdly Hystrichosphaeridium?, fourthly Baltisphaeridium (Appendix A), fifthly Prolixosphaeridium?, sixthly (and now) Tanyosphaeridium. Taxonomic junior synonym: Hystrichosphaeridium (as Tanyosphaeridium) magdalium, according to Stover and Evitt (1978, p.85). The name Hystrichosphaera xanthiopyxides was not validly published in Wetzel (1933b), since the generic name Hystrichosphaera was not validly published until 1937. Age: Late Cretaceous (?Maastrichtian, according to Sarjeant, 1985b, p.143).
