Rank: Genus
Taxonomic discussion:

This genus comprises species with biserially arranged chambers, most of which are considered benthic, but one extant lineage appears to also live in the plankton during part of its life cycle (Darling et al., 2009). To what degree this also applies to fossil species of Bolivina and whether or not the abundant Neogene fossil biserial planktonic foraminifera should also be assigned to this genus remains unclear. [Brummer & Kucera 2022]

They are being edited as the site is developed and comments on them are especially welcome.
