Extra details from original publication
Cushman and Bermudez erected Truncorotalia in 1949, as a new subgenus of Globorotalia, for all the forms of Globorotalia with a flattened dorsal side, since the genotype of that genus shows a typically biconvex test. The subgenotype of Truncorotalia, as designated by the authors, is Rotalina truncatulinoides d'Orbigny. According to the description of the genus (1949, Cushman Lab. Foram. Res., Contr., vol. 25, pt. 2, p. 36) the surface of the test is ornamented by small papillae surrounding the umbilicus and fine granulations covering the earliest chambers on the dorsal side.
In the lower Ranikot [Paleocene] beds of the Nammal gorge, Pakistan, a group was found which bears a strong resemblance to Globorotalia, but the surface of the test is smooth and shiny throughout. The test is calcareous, rather coarsely perforate, and, like Globorotalia, is hyaline and built of radially arranged crystals of calcite. This laevigate form from the Nammal gorge is referred here to a new genus, Pseudogloborotalia.
The following species were included in the genus Pseudogloborotalia by Haque (1956):
