Rastodentidae are a taxonomic family of minute sea snails, marine gastropod molluscs in the order Sorbeoconcha.

[edit] Description

Shells are small, solid and either smooth or strongly spirally sculptured. The operculum is oval, with a thick grooved peg. The radula has the central and lateral teeth with slender comb-like cusps, similar to those of the Rachiglossa, but there are marginals as well. The males have no penis, a character they share with the Cingulopsidae. The possession of features similar to those of the Rissoids, the Cingulopsids and the Rachiglossids, provide a combination of characters that is unknown in any other single Prosobranch family.
