Pseudococculinidae is a family of small sea snails or false limpets, marine gastropod mollusks in the superfamily Lepetelloidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

The shells are small (less than 6 mm), thin and translucent.

The protoconch shows a long, narrow apical fold.

The asymmetrical radula shows a broad, rachidian tooth that lacks a cusp, four inner lateral teeth, a large pluricuspid tooth, and numerous marginal teeth.

Soft body: the right tentacle is generally modified into a copulatory organ.
