Eisenackia circumtabulata

"circumtabulata" Drugg, 1967, p.15, pl.1, figs.12–13.  Holotype: Drugg, 1967, pl.1, fig.12; Damassa, 1979b, pl.3, figs.14–16; Fensome et al., 1993a, fig.1 — p.1061.  NOW Alisocysta.  Originally Eisenackia, subsequently Hystrichokolpoma, thirdly (and now) Alisocysta, fourthly Agerasphaera (generic name illegitimate).  Quattrocchio and Sarjeant (2003, p.146) retained this species in Eisenackia, but Fensome et al. (in press) returned it to Alisocysta.  Taxonomic junior synonym: Hystrichokolpoma mentitum, according to Schumacker-Lambry (1978, p.42) — however, Lentin and Williams (1981, p.135) retained Hystrichokolpoma mentitum.  Age: Danian.
