Taxonomic discussion: Bermúdez’s (1961) original concept of this family was based on the globigeriniform test morphology and presence of an umbilical bulla. As such, it united various macro- and microperforate genera with convergent morphology that are now considered unrelated. The modern concept of the family has its roots in the work of Parker (1962) (for which see discussion below under Genus Globigerinita). The distinctive microperforate wall texture of Globigerinita (named in Chapter 15, this volume, as the glutinata-type wall) was first described in detail by Fleisher (1974) who also described the same wall in his new genus Tenuitella. Following earlier observations by Jenkins (1965), Fleisher suggested that the more globigeriniform genus Globigerinita had evolved from the more globorotaliform Tenuitella via intermediate forms. [Pearson et al. 2018]

Banner (1982) and Loeblich and Tappan (1984) united Tenuitella and Globigerinita within the Subfamily Globigerinitinae in Family Cassigerinellidae (type genus Cassigerinella). Huber and others (2006) also included Eocene Tenuitella in the Cassigerinellidae. However, as discussed by Pearson and Wade (2009), Chapter 15 (this volume), and Chapter 18 (this volume), we now reject the suggestion that Cassigerinella is closely related to Tenuitella or any other of the Globigerinitidae. [Pearson et al. 2018]

Li (1987) employed the Family Globigerinitidae in a similar sense to that used here, uniting Globigerinita and Tenuitella and a species (‘Tenuitella sp.’) that was later to be included in the genus Mutabella (Pearson and others, 2001), while excluding Cassigerinella. Li and others (1992) implicitly included Globigerinatella in the same group as Globigerinita and Tenuitella because of its microperforate wall. The similarity of the wall texture of Globigerinatella and Mutabella to other Globigerinitidae was confirmed by Pearson and Wade (2009). [Pearson et al. 2018]

BouDagher-Fadel (2012a:146) erected the Family Tenuitellidae to include Tenuitella and Praetenuitella. In our work these genera are considered part of the Globigerinitidae because they share a common wall texture. [Pearson et al. 2018]
