Extra details from original publication
This species differs from Globigerina hexagona Natland, 1938, and Globigerina quinqueloba Natland, 1938, in being more sigmoid in the edge view, less compact and more auriculate than circular in contour. The ventral side is less depressed centrally with the apertural lip extending from umbilical area to periphery more peripheral and prominent.
