"pectiniforme" (Gerlach, 1961, p.195-196, pl.28, fig.14; text-fig.18) Davey et al., 1969, p.16.  Emendations: Sarjeant, 1984b, p.83-84,86, as Areosphaeridium pectiniforme; Stover and Williams, 1995, p.114, as Enneadocysta pectiniformis.  Holotype: Gerlach, 1961, pl.28, fig.14; Sarjeant, 1984b, pl.1, fig.2; pl.4, fig.2; Fauconnier and Masure, 2004, pl.7, figs.4-5.  NOW Enneadocysta.  Originally Baltisphaeridium (Appendix A), subsequently Cleistosphaeridium, thirdly Areosphaeridium?, fourthly Areosphaeridium, fifthly (and now) Enneadocysta.  Taxonomic junior synonym: Areosphaeridium (now Enneadocysta) multicornutum, according to Sarjeant (1984b, p.83-84,86)- however, Stover and Williams (1995, p.112) retained Areosphaeridium (as Enneadocysta) multicornutum.  This combination was not validly published in Davey et al. (1966, p.170), since these authors did not fully reference the basionym.  Age: mid Oligocene.
