Pilsbryspira flucki is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.

(Original description) The shell is similar to Drillia harfordiana var.

On the body whorl they diminish very rapidly below the periphery, and the spiral cords are noticeably enlarged and prominent on the summits of the ribs.

From the shoulder to the suture the surface is buff-white, and the growth striae somewhat lamellar.

;[3] also off Cuba; fossils were found in Pleistocene strata from the Isthmus of Panama: age range: 19.3 x 8.0 Ma.
