Original Description
Test free, trochospiral, periphery carinate, chambers angular, rhomboid, or conical angular-conical. Sutures may be thickened, depressed, flush, or elevated. Wall calcareous, finely perforate; with peripheral band or keel. Surface smooth to pustulate. Aperture interiomarginal, an extra-umbilical-umbilical high arched opening with a lip.

Extra details from original publication
Family Globorotaliidae. Miocene-Pliocene.

Remarks. - This new subgenus differs from the usual globorotaloids in having a high arched opening, showing its relationships to the Globorotalia miozea Finlay lineage. In this lineage, an important one in temperate regions, the ancestor was one of the variants of Globorotalia (Turborotalia) zealandica Hornibrook which gave rise to the G. (G.) miozea group through a stage such as G. 'praescitula' in the New Zealand sequence (Walters, 1965, pp. 109-127). The New Zealand G. 'praescitula' has a very high arched aperture with a lip. The holotype of G. scitula praescitula Blow (1959, p. 221, pl. 19, fig. 128a-c) has a low aperture, as shown clearly in the refigured holotype (Blow, 1969, pl. 4, fig. 22), and it is unrelated to the G. (G.) miozea lineage. The tendency for the G. (G.) miozea group to develop a higher apertural opening is shown by the re-entrant in the upper lip by Walters (1965, figs. 8B, 8C). The G. (G.) miozea group shows the development of a thickened rim or keel, a lineage leading to G. (G.) miotumida Jenkins, G. (G.) miozea conoidea Walters, G. (G.) miozea sphericomiozea Walters, and to the subspecies of G. (G.) conomiozea Kennett.
