Hystrichosphaera pedata Wetzel, 1933b, p.55–56, pl.4, fig.35 ex Downie and Sarjeant, 1965, p.119. Emendation: Sarjeant, 1985b, p.145–146, as Coronifera pedata.

Now Coronifera. Originally Hystrichosphaera?, subsequently Spiniferites?, thirdly (and now) Coronifera. Questionable assignment: Wetzel (1933b, p.55).
Taxonomic senior synonym: Coronifera oceanica, by implication in Sarjeant (1985b, p.145–147), who believed Hystrichosphaera (as Coronifera) pedata to be the senior name — however, Kirsch (1991, p.71) retained the two species.
The name Hystrichosphaera pedata was not validly published in Wetzel (1933b) since the generic name Hystrichosphaera was not validly published until 1937.

Holotype: O. Wetzel, 1933, pl.4, fig.35; Sarjeant, 1985, pl.4, fig.5
Age: Late Cretaceous
