The family Globoquadrinidae was erected by Blow (1979) to include Globoquadrina and Dentoglobigerina plus other genera (Globorotaloides and Globigerinita, which is now regarded as a microperforate genus) that are no longer believed to be closely related. The critical feature that linked these groups, according to Blow, was a shift in aperture from a more extraumbilical to intraumbilical position during ontogeny, and significant differences in wall textures were not taken into account. Olsson and others (2006a) retained the family but in a very different sense, uniting two genera (Globoquadrina and Dentoglobigerina) that were believed, at that time to be nonspinose, and hence were excluded from the spinose Globigerinidae. These genera are now regarded as spinose or descended from a closely related spinose form (see Pearson and Wade, 2015, and Chapter 11, this volume) hence they are now included in family Globigerinidae.
