Gymnobela gypsata is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

[1] (Original description) Shell.— Strong, fusiform, biconical, scalar, shortly, sharply and obliquely ribbed, keeled, constricted at the suture, with a long and rather inflated body whorl and a largish snout.

Sculpture Longitudinals—on each whorl is a strongish angulation, forming a shoulder, crowned by a series of narrow elongated tubercles or short ribs.

The body whorl is very large in proportion to the rest, being long and somewhat tumid, and ends in an elongated, broad, unequal-sided snout.

The aperture is pale buff-coloured within, long and narrow, angulated above, also at the keel, and also, very slightly, at the junction of the columella and the body.

On leaving the body the line of the edge runs quite straight forward for a short distance, and then curves round to the right, running out on the line of the ribs into a high shouldered prominent wing, between which and the body whorl the broad, deep, and rounded anal sinus lies.
