Ciperoella Olsson and Hemleben n. gen. is
erected for Oligocene spinose species that have
a neogloboquadrinid-type wall texture and 4½-5
similarly sized chambers in the final whorl. Four
species are recognized as distinct, namely Ciperoella anguliofficinalis (Blow), Ciperoella angulisuturalis
(Bolli), Ciperoella ciperoensis (Bolli), and Ciperoella
fariasi (Bermúdez). Their taxonomy, phylogeny, and
biostratigraphy is discussed
