Original Description
Test large to moderate in size, high-spired convex trochospire composed of four to three and a half chambers per whorl; test periphery moderately inflated, bluntly angled in lateral view ; wall calcareous, non-spinose, very thickly covered with heavy pustules but leaving coarse perforation on spiral and umbilical sides since the young stage; aperture umbilical-extraumbilical, low interiomarginal arch not distorted by a swelling of the last chamber.

Extra details from original publication
Remarks: This species resembles Turborotalia hirsuta (d’Orbigny) but di¡ers from it essentially in having more thickened wall since the young stage (compare Plate II, 5 with Plate II, 3, which represents a young form of T. hirsuta). The new species is absent above the middle of MIS 4 but increases downward in reaching the maxima in MIS 7 and 10 of core NP36 (Fig. 9).
