Globigerinoides rubriformis

Citation: Globigerinoides rubriformis Subbotina 1953
Rank: Species

Current identification:


Original Description
[Translation from the Russian.- Test highly conical, in this feature resembling Bulimina, consisting of 3-3ÃÉÂÇÃÇÂ_ whorls with 3 chambers in each whorl. Dorsal side turrent-shaped spiral with a conical end; the ventral side is the base of the cone. Chambers spherical, very closely adjacent to one another. In most specimens, the outline is rimlike on the dorsal side, and semispherical on the ventral side. The chambers in the final whorl are very large compared to those in the preceding whorls. The sizes of the chambers barely differ within a single whorl. Only in the final whorl do the chambers increase rapidly in size. Sutures simple, depressed, and slightly curved. Aperture is a large semirounded opening on the ventral surface of the final chamber. Wall very often finely porous, smoother than in other representatives of the genus. Sometimes the wall is coarsely porous, especially in large specimens. Dimensions of the holotype (fig. 6a-c): Diameter 0.36 mm.; thickness 0.58 mm.

Editors' Notes
Problematica - Although Subbotina described this species as having supplementary apertures, the illustrations on her pl. 14 which include the holotype do not show such apertures. There is much confusion on the identification of this species by various authors. Needs further study.
