Fusiturris undatiruga, common name the wrinkled turrid, is a species of sea snail, a marine gastropod mollusk in the family Fusiturridae.

The whorls are angulated in the middle and nodulous on the angle.

Above it, the surface is smooth; below the nodules, they are continued as flexuose wrinkles or ribs, becoming evanescent towards the base of the aperture.

The color of the shell is yellowish brown, with usually one or two darker bands.

[3] This species occurs in the Mediterranean Sea and the Atlantic Ocean off the Canaries, Gabon and Angola.
