Original Description
Shape of test low trochospiral, biconvex; equatorial periphery lobate, in small specimens slightly elongate; axial periphery rounded. Wall calcareous, perforate, surface finely cancellate. Chambers ovate to spherical; about 11-14, arranged in 2-2½ whorls; the 4-5 chambers of the last whorl increase fairly rapidly in size. Sutures on spiral side slightly curved to radial, depressed; on umbilical side radial, depressed. Umbilicus fairly wide, open in immature specimens, in mature specimens partly or completely covered by bulla-like chamber. Aperture a slit or low arch ; interiomarginal, umbilicalextraumbilical in early stage, later becoming interiomarginal, umbilical, which in mature specimens becomes covered by a bulla-like chamber with usually one, rarely two or more infralaminal apertures. Coiling random or some predominance for dextral. .

Size: Largest diameter of holotype 0.35 mm

Etymology: The species is named for Dr. H. H. Suter in recognition of his contribution to the geology of Trinidad.

Extra details from original publication
Stratigraphic range (in Cipero formation): Most common and typical in the Globigerina ampliapertura zone, ranging to the Globigerinatella insueta zone.

Remarks: Globorotaloides suteri, new species, is distinguished from G. variabilis, new species, by the more inflated early chambers, less curved sutures and fewer chambers.
