Taxonomy

Citation: Globigerinita glutinata (Egger, 1893)
Rank: species
Basionym: Globigerina glutinata
Synonyms:
  • Globigerinita naparimaensis Bronnimann [according to Akers and Dorman 1964; Kennett & Srinivasan 1983]
  • Globigerinita incrusta Akers [according to Akers and Dorman 1964; Kennett & Srinivasan 1983]
  • Tinophodella ambitacrena Loeblich and Tappan [according to Akers and Dorman 1964; Kennett & Srinivasan 1983]
  • Globigerina juvenilis Bolli [according to Kennett & Srinivasan 1983]
Taxonomic discussion: This species shows a wide range of variation in the development of umbilical bulla, from a completely nonbullate Ga. glutinata morphotype (PI. 56, Fig. 3) to a bullate Ga. ambitacrena morphotype (PI. 56, Fig. 4). Variation between these two extreme morphotypes within single samples shows that they are a single species.

Short diagnosis: Low trochospire

Description


Test morphology: Test small, low to medium trochospiral, equatorial periphery lobulate, chambers spherical to subglobular, 3 to 4 in the final whorl, increasing rapidly in size; sutures nearly radial, depressed; surface smooth with irregularly distributed fine per- forations largely covered by small, subconical tubercles or crystallites; primary aperture interiomarginal, umbilical, a low arch with a thin lip (PI. 56, Fig. 3). In some individuals covered by an irregular bulla expanding along the earlier sutures with numerous infralaminal supplementary apertures bordered by tiny arched or tubulose openings (PI. 56, Figs. 1,4). [Kennett & Srinivasan 1983]

Size: >150µm

Biogeography and Palaeobiology


Geographic distribution: Tropical to subpolar [Kennett & Srinivasan 1983]

Phylogenetic relations: Ga. glutinata is closely related to Ga. uvula but is larger and less trochospiral. Ga. glutinata is one of the long-ranging planktonic foraminiferal species in the Neogene and is ancestral to Globigerinatella and Candeina. [Kennett & Srinivasan 1983]
