Partulidae is a family of air-breathing land snails, terrestrial gastropod mollusks in the superfamily Pupilloidea.[1]
The family is endemic to Pacific islands.[2][3][4]
Genera
The Partulidae are divided into five genera:[4][5]
- Eua has four species, confined to Tonga and Samoa.
- Palaopartula Pilsbry, 1909- has three species, restricted to the Palau.
- Partula Pilsbry, 1909 - has about 100 species, distributed from New Guinea to the Society Islands.
- Samoana Pilsbry, 1909 - has about 23 species, distributed in Polynesia and the Mariana Islands.
- Sphendone has a single species from the Palau.

Anatomy
In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).[7]
Significance
The Partulidae represent a significant species radiation and were important in the development of modern evolutionary studies through the work of Henry Crampton in the early 20th century and later by Bryan Clarke, James Murray and Michael Johnson.
Status
Most Partulidae species have declined since 1974 and a very large proportion are extinct. The main threat to their survival has been the introduction of the predatory snail Euglandina rosea.[4]
