taxonomic family of minute seasnail s, marinegastropod mollusc s in the orderSorbeoconcha .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 theRachiglossa , but there are marginals as well. The males have no penis, a character they share with theCingulopsidae . 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.Genera within the family Rastodentidae
