Necrobroomea eilema
Necrobroomea eilema (Duxbury, 1977) Below, 1990
Now Aprobolocysta. Originally (and now) Aprobolocysta, subsequently Necrobroomea.
Lentin and Williams, 1993, retained this species in Aprobolocysta.
Holotype: Duxbury, 1977, pl.14, figs.4-5, text-fig.19B; Pourtoy, 1988, pl.3, figs.1-3,5-6
Locus typicus: Speeton, England
Stratum typicum: Hauterivian
Original description: Duxbury 1977, p. 53: Aprobolocysta eilema
Diagnosis: An elongate ovoidal proximate cyst. Epitract longer and more tapering than hypotract. Endophragm densely granular. Periphragm relatively delicate, finely perforate, usually extensively folded and enclosing the inner body loosely. The cingulum is reflected in a high undulating periphragm fold. A second high periphragm fold runs from the reflected cingulum to the antapex. No tabulation is apparent exept along the margin of the apical archeopyle.
