Helicinidae gen. & sp. ‘Rapa Nui’

Rapa Nui Helicinid Land Snail (Helicinidae gen. & sp.)  

This taxon is known so far only from a single apical fragment of a shell that was found during excavations at Anakena at the north coast of Rapa Nui in 1991.

Despite its fragmented character it could at least be assigned to the family Helicinidae which is widely distributed in the Pacific region, occuring on all higher islands. [1]

The Rapa Nui Helicinid Land Snail was certainly endemic to the island.
