Original Description

Shape of test medium to high trochospiral ; equatorial periphery distinctly lobate. Wall calcareous, perforate, surface finely pitted, with short spines on well preserved specimens (figs. l0a-c). Chambers spherical to very slightly compressed laterally; 15-20, arranged in 3-4 whorls; the 5-6 chambers of the last whorl increase moderately in size. Sutures on spiral side radial, depressed; on umbilical side radial, depressed. Umbilicus fairly wide, deep. Aperture high, covered above by an elongate, toothlike flap; interiomarginal, umbilical. Coiling random in the Catapsydrax dissimilis zone, later becoming predominantly sinistral (as is also Globoquadrina altispira altispira and Globoquadrina dehiscens; Bolli, 1951).

Size:
Largest diameter of holotype 0.7 mm.

Etymology:

Extra details from original publication
Stratigraphic range (in Cipero and Lengua formations): Catapsydrax dissimilis zone to Globigerinatella insueta zone and Globorotalia fohsi robusta zone to Globorotalia menardii zone.

Remarks: Globoguadrina aitispira globosa, new subspecies, is distinguished from G. aitispira aitispira (Cushman and Jarvis) by having more globular chambers.
