            Starting from November 2009, and for the first time in the environmental history of Santa Catarina - SC, little central portion of the Southern Brazil region (Agudo & Bleicker 2006 a, Agudo 2007, Agudo-Padrón & Bleicker 2009), it is studied and discussed "integrally" the confirmed presence of introduced and invading exotic molluscs in your territory. This event happens in form of official seminars (Oficial State Program for  Listing and Control of  Invasive Exotic Species), organized and driven by the Oficial Santa Catarina’s State Environment Foundation (Fundação do Meio Ambiente – FATMA) jointly with the Hórus Institute of Development and Environmental Conservation (Instituto Hórus de Desenvolvimento e Conservação Ambiental), seeking as main goal the construction of  a “Official State List of Species” (Agudo-Padrón 2011).

 

            Until the moment, they were fully verified for the State a total of twenty one ( 21 ) molluscs species under this condition (48% of the total confirmed in Brazil), being 15 Gastropoda & 6 Bivalvia (12 terrestrial, 5 limnic / freshwater – 3 gastropods & 2 bivalves, 4 marine bivalves) – including the slug Pallifera sp, species in taxonomic determination process – with base foundation in the contributions of AGUDO & BLEICKER (2006 b), AGUDO-PADRÓN (2008 b) and AGUDO-PADRÓN & LENHARD (2010). Of this, 14 are specific invading forms (10 Gastropoda – 9 terrestrial & 1 freshwater – and 4 Bivalves – 2 freshwater & 2 marine).

  

            Of  two (2) participant researchers in the Mollusc Group, only one work with special emphasis in continental species. It is worth to highlight that the Asian golden mussel, Limnoperna fortunei (Dunker, 1857), terrible invader species happily still until the moment moderated in the territory of the State (Agudo-Padrón 2007, 2008 a; Agudo-Padrón & Lenhard 2010: 37, 38), it received matter attention in the mark of this event. For other part, the mussel of cultivation Perna perna (Linnaeus, 1758) it was suppressed of the lists, after extensive analysis and conclusive technical discussion, being considered a native species – in Brazil and SC (Magalhães et al 2007; Schaefer et al 2009).

 

            To follow, a list and relationship of confirmed introduced and invading molluscs in Santa Catarina’s State, SC, are presented, based mainly in the taxonomic contributions of SIMONE (2006) and THOMÉ et al (2006, 2007):
