Enneadocysta dictyostila
From Fensome et al., 2019:
Enneadocysta dictyostila (Menéndez, 1965, p.11–12, pl.2, fig.6; pl.3, figs.18–22) Stover and Williams, 1995, p.109. Emendations: Sarjeant, 1981, p.115, as Areosphaeridium dictyostilum; Fensome et al., 2007, p.396–397, as Enneadocysta dictyostila. Holotype: Menéndez, 1965, pl.2, fig.6; pl.3, figs.18–20. Originally Hystrichosphaeridium, subsequently Oligosphaeridium?, thirdly Areosphaeridium, fourthly Enneadocysta?, fifthly (and now) Enneadocysta. Stover and Williams (1995, p.109) questionably assigned this species to Enneadocysta; however Fensome et al. (2007, p396) included it without question. Taxonomic senior synonym: Hystrichosphaeridium (now Areosphaeridium) diktyoplokum, according to Eaton (1971, p.359) — however, Sarjeant (1981, p.115) retained Areosphaeridium (now Enneadocysta?) dictyostilum. Taxonomic junior synonyms: Enneadocysta partridgei, according to Fensome et al. (2007, p.396); Areosphaeridium (now Enneadocysta) arcuatum and Cordosphaeridium
(now Cooksonidium) capricornum, both according to Sarjeant (1981, p.115–116) — however, Lentin and Williams (1985, p.26) retained Areosphaeridium (now Enneadocysta) arcuatum and Cordosphaeridium (now Cooksonidium) capricornum. Age: Tertiary.
