New additions to the landmollusk fauna of the Juan Fernández Archipelago (Chile) are presented for the firsttime since ODHNER (1922). The specimens were collectedincidental to arthropod species obtained by the Berlese method in RobinsonCrusoe Island in 2011. Anew Charopidae Neoparyphantopsiscrusoeana gen. and sp.n. is described.. Anew name is established for the achatinellid Tornatellina aperta ODHNER 1922 (non Tornatellina aperta PEASE1864). A new combination is proposed for Punctum conicum, transferring this species from the genus Punctum MORSE,1864 of family Punctidae to the genus SinployeaSOLEM, 1983, of the family Charopidae; and five speciesbelonging to the genera Tornatellina PFEIFFER1842, Fernandezia HYATT &PILSBRY 1911, AmphidoxaALBERS 1850 and SinployeaSOLEM 1983 are re-described. Also, the first occurrence ofa Vertiginidae species in Chileis recorded. All of the studied taxa are so far endemic to the Juan FernándezArchipelago. The present paper confirms the status of Robinson Crusoe Island ashaving the richest fauna of terrestrial snails in Chile relative to its area.
