    Contribution to the knowlegde of the benthic molluscan  thanatocoenosis of  Zannone Island (Pontine Archipelago, Latium, Italy)
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    During the period May 2008-September 2012 were investigated some sediment samples collected by scuba diving at various depths in the waters surrounding the Island of Zannone (Pontine Archipelago, Latium, Italy). Altogether 280 taxa belonging to 156 genera were identified.

    The long journey of Fusinus rostratus (Olivi, 1792) (Gastropoda Fasciolariidae) from Portugal coasts to Venice Lagoon
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    In the present paper the following morpha of Fusinus rostratus (Olivi, 1792) (Gastropoda Fasciolariidae) were investigated: Atlantic, Central and Southern Tyrrhenian Sea, Egadi Islands and the Sicilian Channel, Coasts of North Africa, the Central Adriatic Sea, Upper Adriatic Sea and the Venice Lagoon. Each of these morpha shows such morphological characteristics to be easily separated from the others. It is interesting to observe that the morphotype from the coast of Portugal is by far morphologically the closest to that from Northern Adriatic. A feature common to all the described morphotypes, is the presence of secondary cords, regularly spaced between the primary ones. The aim of this study is to split this species by geographical areas in order to facilitate further studies.

    Phenotypic diversity of Thuridilla hopei (Vérany, 1853) (Gastropoda Heterobranchia Sacoglossa). A DNA-barcoding approach
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    The sacoglossan Thuridilla hopei (Vérany, 1853) shows highly diverse chromatic patterns. Based on the morphological examination of specimens from different Mediterranean localities, we have observed that in spite of this great variability in colours of T. hopei, two major chromatic morphotypes are related to bathymetry. Specimens from deeper water exhibit blue darker and more uniform patterns than individuals from shallower water, which show a more variable, dashed and spotted arrangement of light blue, yellow, orange, white and black pigmentation. A molecular genetic analysis using the mitochondrial COI and 16S rDNA markers has confirmed that all these extremely different chromatic morphotypes belong to a single specific entity, i.e. T. hopei, a sacoglossan with a wide distribution, from Macaronesia in the Atlantic, to the easternmost Mediterranean Sea.

    The molluscs found after the nourishment of the littoral of Terracina (Latium, Italy)
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    In the present paper molluscs found after the beach nourishment carried out in 2006 on the coast of Terracina are reported. Altogether were identified 144 taxa, of which 105 Gastropoda, 37 Bivalvia and 2 Scaphopoda.

    On the systematic position of “Cima” melitensis Mifsud, 1998, with erection of the new genus Mifsudia (Heterobranchia Cimidae)
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    Based on teleoconch and, especially, protoconch features, the new genus Mifsudia is erected for Cima melitensis Mifsud, 1998 and placed in the family Cimidae. The protoconch is hyperstrophic, as in the other cimids. At least, two European fossil species (Cima gantensis Bandel, 2005, from the Middle Eocene of Hungary and Murchisonella cf. obtusa Gougerot & Le Renard, 1978 from Early Oligocene of France) are also included in the new genus. Mifsudia melitensis (Mifsud, 1998) comb. nov., originally described from Malta, is here recorded for the first time from Lampedusa Island, Alboran Sea and the coasts of Mauritania (West Africa).

    Natural values, coastal and marine ecosystems of the Circeo National Park: conservation priorities
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    The variety of environments that characterizes the Circeo National Park must also take into account, in addition to the terrestrial natural values that are present, even the importance of marine and coastal stretches that currently do not benefit from a similar regime of protection, preserving instead important elements of wealth for marine biodiversity. This added value is represented in a particular way by the presence of Posidonia oceanica (L.) Delile, 1813, habitat of Community interest. The proposal of the Plan of the Park to extend to the sea The Circeo National Park would help to protect and enhance areas for the most part already included in the Natura 2000 network that could be handled in a unified manner by the Park providing for their conservation through various management interventions. Another proposal involves, instead of creating a true marine protected area, encompassing the whole Posidonia meadows present both in the northern section of the coast and in the south, between San Felice and Terracina and, hopefully also the stretch of sea that surrounds the island of Zannone (therefore including the SPAs area regarding the Pontine Archipelago).

    The continental molluscs from Mount Circeo (Latium, Italy)
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    This paper is the second step in a process that aims to asses biodiversity of land and freshwater molluscs fauna of Mount Circeo (Latium, Italy). Forty species of land and freshwater molluscs are listed, three more than in the previous work. A species of Oxychilus Fitzinger, 1833 and two species of Limax Linnaeus, 1758 remain undetermined, to date. The presence of Pleurodiscus balmei balmei (Potiez et Michaud, 1838) and Siciliaria gibbula honii (O. Boettger, 1879) are confirmed and this is the known northern limit of their distribution areas in Italy. Moreover, the presence of some species of biogeographical interest has allowed us to formulate some hypotheses on the origin of this fauna, in the light of the most recent theories on the formation of the Italian peninsula.
