Gymnobela imitator Dall, 1927 Pleurotomella imitator is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

The axial sculpture consists of (on the body whorl about 14) narrow, oblique ribs with wider interspaces, crossing the whorls, stronger on the earlier whorls, and ending in small close beadlike pustules in front of the suture.

The spiral sculpture consists of a single carina near the periphery of the whorls, prominent where it intersects the ribs, and 10 or 12 fine threads in front of the carina which slightly cut the ribs in crossing them.

The anal fasciole is wide, extending from the carina to the coronation of the suture.

[2] This species occurs in the Atlantic Ocean off Georgia, USA.
