(Note: this is a living species; we restrict this synonymy list to references that are relevant to Oligocene to lower Miocene occurrences. - Pearson et al. 2018) This species is common in the Neogene but also occurs rarely in the Oligocene (Quilty, 1976; Kennett and Srinivasan, 1983; van Eijden and Smit, 1991; Spezzaferri, 1994; Pearson, 1995). We defer detailed treatment to future works on modern and Neogene taxonomy. [Pearson et al. 2018]

Geographic distribution
Subpolar to tropical, common in temperate and subpolar assemblages. [Kennett & Srinivasan 1983]
In modern oceans an abundant, temperate water, species [SCOR WG138]Map of distribution from ForCenS database
Descended from Globigerinita glutinata in the Oligocene (cf. Spezzaferri, 1994). [Pearson et al. 2018]
Molecular Genotypes recognised (data from PFR2 database, June 2017. References: André et al. 2014; Ujiié & Lipps 2009; Stewart et al. 2001).
Most likely ancestor: Globigerinita glutinata - at confidence level 3 (out of 5). Data source: Spezzaferri, 1994; Pearson et al. 2018.
The lowest recorded occurrence is in upper Zone O5 (Quilty, 1976:662; near the top of Zone N2). It becomes more common towards the upper part of the Oligocene.
