"speciosa" Deflandre, 1937b, p.65, pl.11 (al. pl.8), fig.2. Holotype: Deflandre, 1937b, pl.11 (al. pl.8), fig.2. NOW Spiniferites?. Originally Hystrichosphaera, subsequently Spiniferites, thirdly (and now) Spiniferites?. This name was not validly published in Deflandre (1934, caption to fig.4 - p.967; 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: Late Cretaceous.
Parent: Hystrichosphaera
