Extra details from original publication
Remarks. This new genus is distinguished from Tenuitella and Globigerinita by its bullate, intraextraumbilical, primary aperture. It may have been derived directly from Tenuitella (possibly T. fleisheri), whereas bullate Globigerinita with intraumbilical primary apertures developed also from Tenuitella, but via a transitional stage, which is recognized as Tenuitellinata spp. The Oligocene-Miocene bullate species, Globigerinita praestainforthi Blow, is superficially similar to the forms included here, but possesses an anterointraumbilical primary aperture (see Fig. 4), and is correctly assigned to Globigerinita.
