"Shape of test very low trochospiral, spiral side almost flat, inner whorls occasionally slightly raised, umbilical side strongly flat, inner whorls occasionally slightly raised, umbilical side strongly convex; equatorial periphery slightly lobate, nearly circular; axial periphery angular with pronounced keel which is ornamented with spines in well-preserved specimens.

Chambers angular, inflated, 15 to 18, arranged in about 3 whorls; the 6 to 8 chambers of the last whorl increasing slowly in size. Sutures on spiral side curved; on umbilical side radial, depressed. Umbilicus fairly wide, deep, open. Aperture a low arch; interiomarginal, extraumbilical-umbilical. Coiling about 90% dextral in the Globorotalia formosa formosa zone, becoming predominantly sinistral in the Globorotallia aragonensis zone (up to 60%). Largest diameter of holotype 0.65 mm.
