Barbatacysta pilosa

pilosa (Ehrenberg, 1854, pl.37, section 8, fig.4) Courtinat, 1989, p.187.  Emendation: Erkmen and Sarjeant, 1980, p.51, as Sentusidinium pilosum.  Holotype: Ehrenberg, 1854, pl.37, section 8, fig.4.  Originally Xanthidium pilosum (Appendix A), subsequently Hystrichosphaera pilosa (combination not validly published), thirdly Hystrichosphaeridium pilosum, fourthly Baltisphaeridium pilosum (Appendix A), fifthly Ovum hispidum subsp. pilosum (combination not validly published; Appendix A), sixthly Cleistosphaeridium pilosum (combination not validly published), seventhly Tenua pilosa, eighthly Sentusidinium pilosum, ninthly Batiacasphaera pilosa, tenthly (and now) Barbatacysta pilosa.  This species may not have been validly published in Ehrenberg (1854) as no description has subsequently been referenced (or found by the present authors in the Ehrenberg's huge tome). In transferring this species to Hystrichosphaerdium, Deflandre (1937b, p.79) noted that Ehrenberg's figure appeared insufficient for meaningful identification.  The validity/authorship of this name may need to be reconsidered as it appears that Ehrenberg (1854) did not provide a description.  Age: Oxfordian.
