From Fensome et al., 2019:
Coronifera striolata ssp.? minor Wetzel, 1933b. p.45–46. pl.4, fig.26 ex Sarjeant, 1984c, p.132. Holotype: Wetzel, 1933b, pl.4, fig.26. Originally Hystrichosphaera hirsuta forma minor (name not validly published), subsequently
Baltisphaeridium hirsutum forma minus (combination not validly published; Appendix A), thirdly
Operculodinium hirsutum subsp. minus (combination not validly published), fourthly (and now) Coronifera
striolata subsp. minor?. Questionable assignment: Sarjeant (1984c, p.132). This taxon was first described
and illustrated in Wetzel (1932, caption to pl.3, fig.13 — p.144; pl.3, fig.13) but the name was not validly
published since the species name Xanthidium hirsutum Ehrenberg, 1837b was not validly published and
additionally since the generic name Hystrichosphaera Wetzel, 1933b was not validly published at that time.
Sarjeant (1984c, p.132) validly published this name, as Coronifera striolata subsp. minor and noted that the
attribution was "emphatically provisional". This is possibly a taxonomic synonym of Hystrichosphaera
hirsuta forma minor (name not validly published), which has a different holotype. Age: Late Cretaceous.
