    Mollusca and environmental conservation in Santa Catarina State (SC, Southern Brazil): current situation

    Available knowledge of malacofauna (mollusc species) conservation in the territory of Santa Catarina State, SC, central Southern Brazil region, is shortly analyzed and discussed herein. Present data originate from the author's active participation in three recent regional unpublished events dealing with biodiversity conservation in the State, carried out to cope the sensitive lack of population studies which is the main difficulty to face in order to provide accurate and detailed evaluations on biodiversity and its conservation status.

    Current knowledge on population studies on five continental molluscs (Mollusca, Gastropoda et Bivalvia) of Santa Catarina State (SC, Central Southern Brazil region)

    Although still very scarce, available knowledge on population studies on continental (land and freshwater) molluscs in the territory of Santa Catarina State is shortly analyzed and discussed. Based on the IUCN “Restricted Distribution” criterion, a total of 54 nominal species, including 31 terrestrial gastropods, 15 freshwater gastropods and 8 limnic bivalves, were considered strong candidates as threatened taxa. Out of all these endangered species, only 5 limnic forms (2 gastropods and 3 bivalves) were previously analysed, in some way, at population level.

    New corological and biological data of the Red Gum Lerp Psyllid, Glycaspis brimblecombei Moore, 1964 in Italy (Hemiptera, Psyllidae)

    Glycaspis brimblecombei Moore, 1964 is a psyllid (Hemiptera: Psyllidae) pest of Eucalyptus, native to Australia and first recorded in Europe: Spain in 2008 and more recently (2010) in Italy. The present paper deals with recent research, carried out in central Italy, with new data on the distribution and biology of this species.

    On the increasing occurrence of the Bluespotted Cornetfish Fistularia commersonii (Rüppel, 1838) in the Central Mediterranean (Osteichthyes, Fistulariidae)

    The increasing occurrence of the blue-spotted cornet fish Fistularia commersonii, a highly successful Lessepsian migrant, within coastal waters of Sicily and of the Maltese Islands is hereby recorded. Reports of recent sightings of the species within such a marine area are documented and these suggest the establishment of viable populations for the species within the same marine area.

    New records of Testacella scutulum Sowerby, 1821 (Gastropoda, Pulmonata, Testacellidae) from Southern Italy and Sicily

    In the present paper we report on Testacella scutulum recently recorded for a few regions of Southern Italy and Sicily. An updated distribution map, anatomical remarks and feeding behaviours of collected specimens are related in order to extend and improve general knowledge on these terrestrial molluscs.

    New ecological and taxonomical data on some Ptenoglossa (Mollusca, Caenogastropoda) from the Gulf of Catania (Ionian Sea)

    Ptenoglossans, well known as parasites of marine invertebrates, are one of the less common and less studied groups of caenogastropods. Most of the α-taxonomy of their Mediterranean representatives is still source of debate and very few data are known on their ecology. A considerable amount of fresh and living material of several ptenoglossan from the Gulf of Catania was available for study. Based on this material we here provide information on the distribution and ecology (e.g. habitat and host preference) of some relevant ptenoglossan species. In particular the distribution of Similiphora similior (Bouchet & Guillemot, 1978), Pogonodon pseudocanarica (Bouchet, 1985), Cerithiopsis ladae Prkic & Buzzurro, 2007, Epitonium pseudonanum Bouchet & Warén, 1986, Melanella lubrica Monterosato, 1890, and Pelseneeria minor Koehler & Vaney, 1908 were extended to the Ionian Sea and the host is reported for: two triphorids, one cerithiopsid, one epitoniid, three Melanella Bowdich, 1822 and other two eulimids. The particularly good conditions of the material studied also allowed some novel and important observations on the morphology to be made and provided the opportunity to discuss the taxonomy of some groups. Descriptions of the head-foot colour pattern were provided for one triphorid, three species of Cerithiopsis Forbes & Hanley, 1851, one epitoniid and three eulimids.
