This paper reports for the first time four exotic terrestrial slugs species in Argentina: Lehmannia valentiana (Limacidae), Deroceras invadens (Agriolimacidae), Arion intermedius (Arionidae) and Meghimatium pictum (Philomycidae). The study is based on 40 lots from northern, central and southern Argentina, including material recently collected and also from museums. Both morphological characters and mitochondrial cytochrome oxidase I (COI) gene sequences were used to identify the invasive species. In order to investigate their origin, phylogenetic analysis were also carried out. Lehmannia valentiana has the oldest records and is distributed in north, central and south of the country. Deroceras invadens and A. intermedius were recorded in southern Argentina with abundant records. Deroceras invadens was molecularly related with samples of diverse geographical origins (e.g. Germany, South Africa, Canada, USA). Records for M. pictum were obtained from the NW and NE Argentina. For M. pictum we suggest that the origin of South American invasive lineage would be located in a region at the west of the Strait of Taiwan. Due to the potential of these species of affecting the local biodiversity, to turn into a plague or to be vector of diseases, this work, provides essential information for governmental authorities responsible for managing and controling exotic species.
