"wetzelii" Deflandre, 1937b, p.65, pl.11 (al. pl.8), figs.6,8. Holotype: Deflandre, 1937b, pl.11 (al. pl.8), figs.6,8. NOW Rottnestia. Originally Hystrichosphaera, subsequently Hystrichosphaeropsis (combination not validly published), thirdly Spiniferites, fourthly (and now) Rottnestia. This name was not validly published in Deflandre (1935, p.232; 1936a, p.63) since the generic name Hystrichosphaera was not validly published until 1937 and, additionally, since no description was given. Age: Senonian.
Parent: Hystrichosphaera
