The name ruber is from the colour of the pink chromotype, the taxonomic significance of the colouration was long doubted but molecular genetic data has strongly supported separation of these two types as discrete species (Aurahs et al. 2011, Morard et al. 2019).
The pink form first occurs in the fossil record at ca 750ka and disappears from the Indian and Pacific Oceans at ca 120ka (Thompson et al. 1979).

In modern oceans an abundant, warm water, species [SCOR WG138] Gs. ruber is easily distinguished by the position of the primary and supplementary sutural apertures, which are always symmetrically placed above the suture between two earlier chambers. During the Pleistocene to Recent, Gs. ruber shows a wide range of variation in the height of the spire and tightness of the test coiling. Several taxa have been recognized to reflect these variations - for instance, Gs. pyramidalis (van Den Broeck) for forms with a high trochospire, Gs. elongatus (d'Orbigny, 1826) for forms with tightly coiled trochospire , and Gs. cyclostomus (Galloway and Wissler, 1927) for forms with a more compact test and relatively small aperture. We consider all of these forms to be phenotypic variants of G. ruber. We believe that Gs. ruber evolved from Gs. subquadratus during the late Middle Miocene Zone N15. Instead, Blow (1969) suggested the ancestry of Gs. ruber to be from Gs. bolli within Zone N16 (Late Miocene), and Cordey (1967) suggested that Gs. obliquus was the ancestral form of Gs. ruber.

NB G. ruber IIa is now regarded as a separate species, G. elongatus, following Aurahs et al. (2011). Genotypes G. ruber Ia, Ib, Ib2 & IIb are all characteristic of G. ruber white (Aurahs et al. 2011).
Most likely ancestor: Globigerinoides subquadratus - at confidence level 3 (out of 5). Data source: Kennett & Srinivasan 1983, fig. 10.
