Abstract Contents:

The occurrence of the asiatic golden mussel Limnoperna fortunei (Dunker, 1857), only freshwater/ limnic representative known of the Family MYTILIDAE (an invasive introduced species), is confirmed for first time in Santa Catarina State/ SC and the system of the Upper Uruguay River Basin. Presumably introduced in this region as a consequence of anthropic actions, and showing a relatively low population density, in June 11 2012 five field pictures an a lot (random sample) compound of 19 specimens of this exotic species were examined, presenting sizes between 6,0 and 17,0 mm of length, collected by the Technical BAESA José Manuzzi (May 30 2012) in the reservoir area comprised between “Barra Grande” and “Machadinho” hydroelectric power plant installations, Pelotas River Basin in Anita Garibaldi Municipal District. Comparative material finally deposited in the scientific malacological collection of the “Museum of Sciences and Technology”, Pontifical Catholic University of Rio Grande do Sul - PUCRS, Porto Alegre/ RS (MCP 09547). Additionally, a second lot compound of 14 specimens coming from the same locality and presenting the same biometric characteristics, was deposited in the mollusks collection from the “Ecology and Zoology Department”, Center for Biological Sciences, Federal University of Santa Catarina State - UFSC, Florianópolis/ SC (CMOUFSC s/c).

Abstract Contents:

Starting from the year 2008, based on extensive literature review and examination of specimens deposited in institutional collections, including samples obtained in the course of work/ field studies, this contribution includes the record of over 32 specific known taxa (9 limnic/ freshwater & 23 terrestrial). Prior systematic inventory of the continental molluscs of Santa Catarina’s State/ SC, the geo-politics smaller portion of the southern Brazil region, including 28 Gastropoda (1 HELICINIDAE, 3 HYDROBIIDAE, 1 THIARIDAE, 1 ANCYLIDAE, 5 SUBULINIDAE, 4 BULIMULIDAE, 1 AMPHIBULIMIDAE, 1 ODONTOSTOMIDAE, 1 STREPTAXIDAE, 3 SYSTROPIIDAE, 5 CHAROPIDAE, 1 GASTRODONTIDAE/ ZONITIDAE - exotic, 1 VERTIGINIDAE - exotic) & 4 Bivalvia (1 HYRIIDAE, 1 MYCETOPODIDAE, 1 CORBICULIDAE, 1 MYTILIDAE - exotic) distributed in 26 genera and 17 families. Our studies increased to a new total of 192 species and subspecies known regionally. Two alien species were confirmed:  Meghimatium pictum (Stoliczka, 1873) (PHILOMYCIDAE) and Lehmannia valentiana (Férussac, 1823) (LIMACIDAE). Regard the new records, the asiatic golden mussel Limnoperna fortunei (Dunker, 1857), only freshwater/ limnic representative known of the Family MYTILIDAE (an invasive introduced species), the freshwater native snail Aylacostoma sp. (THIARIDAE), the rare arboreous native snail Macrodontes thielei Pilsbry, 1930 (ODONTOSTOMIDAE), Cyanocyclas (= Neocorbicula) limosa (Maton, 1809) (a native representative of the family CORBICULIDAE) and, finally, the native freshwater mussel/ naiad Diplodon (Rhipidodonta) koseritzi (Clessin, 1888) (HYRIIDAE considered in “endangered” status), comparative material was deposited in the scientific malacological collection of the “Museum of Sciences and Technology”, Pontifical Catholic University of Rio Grande do Sul - PUCRS, Porto Alegre/ RS (MCP  09559).
