Original Description

Test free, coiled in a low trochospire with 14 to 15 chambers in all arranged in about two and one-half whorls, four to four and one-half in the final whorl; earlier whorls distinctly high trochospiral, protruding conically on the spiral side; chambers subspherical to ovate, gradually increasing in size as added; equatorial profile subrhomboidal to subquadrate, equatorial periphery lobulate; axial periphery broadly rounded; sutures of the spiral side depressed and nearly radial; sutures of the umbilical side strongly depressed and becoming nearly incised toward the umbil icus, radial to slightly curved; umbilicus fairly wide and deep; aperture interiomarginal, umbilical extraumbilical, low-arched with a distinct toothlike flap; wall calcareous, coarsely pitted; surface granular in appearance.

Size:
Maximum diameters: Holotype (plate 3, figures 6a-6c). 0.43 mm.; paratype (plate 3, figures 4a-4b) 0.52 mm.; other unfigured paratypes range from 0.43 mm, to 0.53 mm.

Etymology:

Extra details from original publication
Remarks: This species is distinguished from Globoquadrina asanoi, n, sp., by having an aperture that is approaching an umbilical-extraumbilical position, subrhomboidal to subquadrate equatorial periphery, and the last whorl often consisting of four and one-half chambers instead of four as in G. asanoi.
