Pseudorhaphitoma iodolabiata is a small sea snail, a marine gastropod mollusk in the family Mangeliidae.

The interstices show extremely fine and regular spicules.

The suture runs straight and is not very distinct, giving the whorls a subulate aspect.

The outer lip is sharp and is strongly thickened by the last axial rib.

On its inside it is denticulate with three or four obsolete teeth and a parietal tooth next to the sinus.
