Original Description

Test with a subpolygonal lateral outline, strongly compressed along the growth axis. Spire consists of three whorls. Early whorls lie on one level with the surface of the last whorl or rise up slightly above it. In each whorl there are five to six inflated subspherical chambers, rapidly and uniformly increasing in size and arranged freely. Peripherally on the chambers a small papillate projection, directed toward the subsequent chamber, is frequently observed. Last chamber asymmetrical, flattened at the apertural face and slightly shifted toward the umbilical surface. Equatorial outer margin scalloped. Axial outer margin weakly asymmetric, broadly rounded. Sutures deep, straight. Umbilicus narrow. Aperture a semicircular slit located between the umbilicus and the outer margin. Sometimes it is surrounded by a very narrow lip, the width of which is uniform over its whole length. Wall smooth, finely perforate. Surface lustrous or matte.

Greatest diameter 0.45, least diameter 0.32, height 0.21 mm

Extra details from original publication
Variability - The form of the test, changing from oval to rounded, and the number of chambers in a whorl are not constant. Tests are predominant in which the last whorl there are five to six chambers, but are encountered with four and a half, seven, or eight chambers to a whorl.

Comparison. - From the near species Globigerina cretacea d'Orbigny, 1840, and G. edita Subbotina, 1949, this species differs by its flatter, low test, the often oval outlines, more flattened spiral side, greater number (5-6) of chambers in the last whorl, the asymmetrical shape of the last chamber, which stands above the umbilicus, and the small umbilical aperture.""
