Hystrichosphaeridium xanthiopyxides (O. Wetzel, 1933) Deflandre, 1937
Now Tanyosphaeridium. Originally Hystrichosphaera, subsequently Hystrichosphaeridium, thirdly Hystrichosphaeridium?, fourthly Baltisphaeridium, fifthly Prolixosphaeridium?, sixthly (and now) Tanyosphaeridium.
Morgenroth, 1968, questionably included this species in Hystrichosphaeridium.
Tax. sr. synonym of Tanyosphaeridium magdalium (Drugg, 1967) Heisecke, 1970, according to Stover and Evitt, 1978.
This combination was not validly published in Klement (1960, p.59), since that author did not fully reference the basionym.
Holotype: O. Wetzel, 1933, pl.4, fig.25; Morgenroth, 1968, pl.48, fig.5; Sarjeant, 1985
