Rank: genus
Type species: Globigerinita naparimaensis Brönnimann, 1951
Taxonomic discussion: Globigerinita is characterized by a microperforate surface with extremely small, irregularly distributed perforations. Pore pits are totally absent, but small subconical tubercles or crystallites cover the otherwise smooth surface (Pl. 56, Fig. 1). A bulla is present like Catapsydrax, but the latter is distinguished by its cancellate surface with large pores, distinct pore pits, and relatively larger test size.
Catapsydrax probably evolved from Globorotaloides suteri during the late Middle Eocene and is phylogenetically unrelated to Globigerinita. The surface ultrastructure of Globigerinita is similar to Tenuitella, Globigerinatella, and Candeina, and all of these form a closely related and distinctive group linked by surface ultrastructure unlike any other group of Neogene globigerinacea.

NB The short diagnoses are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They have initially been copied from the diagnostic characters/distinguishing features sections of the Eocene and Paleocene Atlases, they will be edited as the site is developed.


Biogeography and Palaeobiology

Phylogenetic relations: Globigerinita is largely a Neogene genus (Text Fig. 25). It evolved from the subgenus Tenuitella in the Late Oligocene (Fleisher, 1974). In the Early Miocene, Globigerinita developed into Globigerinatella, a geographically restricted and geologically short-ranging genus, and in the Late Miocene it gave rise to Candeina. [Kennett & Srinivasan 1983]

Most likely ancestor: Tenuitella - at confidence level 3 (out of 5). Data source: Kennett & Srinivasan 1983.

Some minor issues.

Type species: Globigerinita naprimaensis

The correct spelling is "naparimaensis".

many thanks for pointing out those mistakes - and I will make the corrections directly.
