Abstract
During the field work of our research into the terrestrial malacofauna of the eastern adriatic islands Šolta, Drvenik veli and Drvenik mali (Croatia) 36 snail species with shells were registered. That almost tripled the number of taxa recorded in the literature. We consider Lindholmiola corcyrensis (rossmässler, 1836) and Delima (Piceata) piceata (rossmässler, 1836), registered in the literature for Drvenik veli, non-existing for the researched area, as well as for Croatia. Of the recorded taxa we particularly refer to Odontocyclas kokeilii (rossmässler, 1837) with Šolta and Drvenik veli being its second i.e. third island localities in Croatia, and the endemic clausilid snail Delima (Semirugata) hiltrudis H. Nordsieck, 1969, also found on Šolta and so far known only from the island of Brač. The greatest number of species were found on the biggest island of Šolta, and the smallest island Drvenik mali had the lowest number of species, as expected. The values of the Whittaker index of biodiversity and of the maximum index of biodiversity increased according to size of island. The average number of taxa per site is the highest on the mid-sized island of Drvenik veli, which is a consequence of the diversity and good state of preservation of its habitats.
