Impletosphaeridium polyozum

?polyozum (Brosius, 1963, p.45, pl.1, fig.6; pl.6, fig.5; text-figs.2a–d) Islam, 1993, p.87.  Holotype: Brosius, 1963, pl.1, fig.6.  Originally Baltisphaeridium (Appendix A), subsequently Cleistosphaeridium?, thirdly Surculosphaeridium, fourthly (and now) Impletosphaeridium?.  Questionable assignment: Islam (1993, p.87).  The epithet is derived from the Greek for "much branched", as implied by Brosius (1963).  Since Principle 5 of the I.C.N. states that taxon names are to be treated as Latin, this epithet should be rendered as "polyozum" in agreement with the neuter gender of the generic name ("polyoza" would be the feminine form and "polyozus" the masculine form).  Age: late Oligocene.
