Tibatrochus incertus is a species of sea snail, a marine gastropod mollusk in the family Eucyclidae.

The six convex whorls are separated by a deep suture, which is waved by the ends of the ribs.

They are crossed on the lower whorls by 2 spiral cords, producing tubercles on the ribs.

The thin outer and basal margin are regularly curved, and slightly thickened interiorly.

The columella is nearly straight, with an inconspicuous tubercle about halfway, near the base with a rounded angle.
