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.
