| Outline of Final Research Achievements |
YYap Islands are oceanic islands that located between Mariana and Palau Islands in the western Pacific. Although there are few fragmentary records of land snails from Yap in 1800th, land snail fauna of the islands have not been known. In this study, land snail fauna of Yap Islands was surveyed and 18 species of land snails were found from the islands. Most of these snails are introduced or widely distributed species, while only three species are considered to be endemic. All diplommatinids from Yap are undescribed and endemic species. It is strongly suggested that these endemic diplommatinids have radiated within the islands. Poor land snail fauna of Yap Islands may be attributable to the small island area, the low altitude, the relatively young age, and the lack of limestone area which is suitable for habitats of land snails.
