The Rapa Nui Molytine Weevil (family Curculionidae: subfamily Molytinae) is known from numerous body parts that were recovered from core samples made in the lake in the crater of the Rano Raraku volcano on Rapa Nui. [1]

The species is known exclusively from these samples of Holocene age and is clearly extinct.
