Pleurotomella aculeata is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

(Original description) The shell is buff-coloured, lighter towards the apex and siphonal canal.

The ribs and keels are about equal in strength, the intersections forming sharp points.

A fine thread is visible in this wide space, there is also a duplication of the posterior keel.

The sinus of the type is so little damaged that to draw it perfect can scarcely be called reconstruction.
