List of Odostomia species

Odostomia is the most speciose genus of minute sea snails, pyramidellid gastropod mollusks.

The genus Odostomia Fleming, 1813 was used by 19th century authors, particularly in the European literature, for most of the smaller Pyramidellidae.

It is still a catchall for most small pyramidellids lacking both axial and spiral sculpture.

For these, the database WoRMS has refrained from making new combinations not backed by (or implicit from) a published source but, unless otherwise noted, the species that were already "accepted" under a subgenus now raised to full genus have been marked as "accepted" under that full genus.

[1] The European and American species of Odostomia differ in several anatomical and shell characteristics.
