Original Description
Test free, trochospiral, biconvex, spire nearly flat, umbilicus small and deep, periphery rounded, peripheral  outline lobulate; chambers globular, increasing rapidly in size, forming about 2½ whorls, commonly with 4 to 5 chambers in the final whorl; sutures distinct, constricted, gently curved to radial; wall calcareous, distinctly perforate throughout, surface finely but prominently hispid; aperture an interiomarginal, extraumbilical-umbilical, high, broad arch.

Size: Greatest diameter of holotype 0.30 mm. Paratype 0.28 mm. in diameter.

Etymology: The specific name comes from the Latin tribiilosus,thorny, and refers to the spinose wall.

Remarks: The species somewhat resembles Globorotalia pseudobulloides (Plummer) in general appearance, differing in the spinose surface. It differs from Globigerina esnaensis LeRoy in being much smaller, and in having more globular chambers.
