Partulidae is a family of air-breathing land snails, terrestrial gastropod mollusks in the superfamily Partuloidea. The family is endemic to Pacific islands.

Genera

Partulidae is divided into five genera:

  • Eua has four species, confined to Tonga and Samoa.
  • Partula has about 100 species, distributed from New Guinea to the Society Islands.
  • Samoana has about 23 species, distributed in Polynesia and the Mariana Islands.
  • Palaupartula has three species, restricted to the Belau islands
  • Sphendone has a single species from the Belau islands

    Anatomy

    In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).

    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.
