Hystrichosphaera penicillata
"penicillata" (Ehrenberg, 1843b, p.62 ex Ehrenberg, 1854, pl.37, section 8, fig.3) Wetzel, 1933b, p.41. Holotype: Ehrenberg, 1854, pl.37, section 8, fig.3. Combination not validly published: generic name not validly published until 1937. NOW Systematophora penicillata. Originally Xanthidium penicillatum (Appendix A), subsequently Hystrichosphaera penicillata (combination not validly published), thirdly Hystrichosphaeridium penicillatum, fourthly Ovum hispidum subsp. penicillatum (combination not validly published; Appendix A), fifthly Hystrichosphaeridium? penicillatum, sixthly (and now) Systematophora penicillata. Taxonomic junior synonym: Systematophora fasciculigera, according to Sarjeant (1980a, p.282). The name Xanthidium penicillatum was not validly published in Ehrenberg (1843b) since neither description nor illustration was presented. The validity/authorship of this name may need to be reconsidered as it appears that Ehrenberg (1854) did not provide a description. Age: late Oxfordian.
