Pseudodaphnella retellaria is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

The radials are narrow, almost lamellate, ending abruptly at the shoulder and gradually on the base, slightly oblique, fourteen widely spaced on the body whorl and on the penultimate sixteen.

These are crossed by spiral threads of smaller gauge, forming long narrow meshes, amounting to sixteen on the body whorl and to six on the penultimate.

The outer lip forms a small varix, ascending the previous whorl and enclosing a C-shaped sinus.
