From Fensome et al., 2019:
Areoligera tenuicapillata (Wetzel, 1933b, p.42, pl.4, figs.20–22 ex Deflandre, 1937b, p.78) Lejeune-Carpentier, 1938a, p.B170. Holotype: Wetzel, 1933b, pl.4, fig.20. Originally Hystrichosphaera (name not validly published), subsequently
Hystrichosphaeridium, thirdly (and now) Areoligera. The name Hystrichosphaera tenuicapillata was not validly
published in Wetzel (1933b), since the generic name Hystrichosphaera was not validly published until 1937. Age:
Senonian.
