    Qanat, Gebbie and water source: the last refuge for the malacologica freshwater fauna in Palermo (Sicily, Italy)

    ABSTRACT
    The surroundings of Palermo were characterized, over the centuries, by the presence of many natural environments of great ecological and faunal importance. These environments were placed in a context characterized by minimal and sustainable urban development and large agriculture areas, dedicated to the development of tree crops such as citrus and orchards. These crops were supported by an imposing irrigation system that, using natural resources such as watercourses, wells and springs, collected and distributed water in soils through tanks, gebbie, qanat, irrigation channels (saje), etc. Fresh water mollusks, like many other animal and vegetable organisms, spread from the natural freshwater environments in this artificial water system, thus creating a unique and varied ecosystem. The subsequent urban development of the city of Palermo and the destruction of many of those natural environments has further enhanced the ecological role of the artificial freshwater systems as an important refuge for the native fauna and flora. In the present study, we report on freshwater molluscs observed in the territory of Micciulla, a large relict area occupied almost entirely by an old citrus, now located inside the city of Palermo. In this area there are some springs, an extensive array of artificial freshwater to irrigate the crops, and the qanat Savagnone located in the “Camera dello Scirocco”. The results obtained by census of different populations of freshwater mollusks confirm the importance of these environments and the growing role they play as the last refuges for fauna and flora originally linked to natural humid environments.

    The endemic door snail of Marettimo (Egadi Islands, Sicily, Italy): Siciliaria (Siciliaria) scarificata (Pfeiffer, 1857) (Pulmonata, Clausiliidae)
    Proceedings of the Eighth Malacological Pontine Meeting, October 4th-5th, 2014 - San Felice Circeo, Italy

    ABSTRACT
    The door snail Siciliaria (Siciliaria) scarificata (L. Pfeiffer, 1856) (Pulmonata Clausiliidae) is redescribed. The species is endemic to Marettimo (Egadi Islands, Sicily, Italy) and it is the only one of the genus Siciliaria Vest, 1867 living in this island. Siciliaria scarificata can be morphologically identified by the presence of a high columellar lamella, ascending in a double “S” curve, a wide anterior upper palatal plica, long basal plica, sulcalis present; clausilium plate distally less narrowed; genitalia are characterized by very short bursa copulatrix duct; short diverticulum of bursa copulatrix; penial papilla conic and short. Notes about its taxonomy, biology and conservation status are also provided.

    The genus Erctella Monterosato, 1894: new molecular evidence
    Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

    ABSTRACT
    In this paper we report on new molecular data (COI sequences) of different and representative populations of Erctella mazzullii (De Cristofori et Jan, 1832), E. cephalaeditana Giannuzzi-Savelli, Oliva et Sparacio, 2012 and E. insolida (Monterosato, 1892) (Pulmonata, Stylommatophora, Helicidae). Present results are compared with those from recent literature and the current knowledge on phylogenetic relationships among Helicidae pulmonate gastropods is reviewed. Obtained results suggest that: i) Cornu Born, 1778 and Cantareus Risso, 1826 are separate and well distinct from Helix Linnaeus, 1758; ii) Erctella Monterosato, 1894 is a valid and independent genus rather than a subgenus of Cornu; iii) Cornu aspersum (O.F. Müller, 1774) is a group of species (i.e. "aspersum" group) whose taxonomic status needs to be defin further studies; iv) Cornu, Cantareus and Erctella might belong to the same tribe that, still, remains to be defined.

    On the presence of Dreissena polymorpha (Pallas, 1771) and Sinanodonta woodiana woodiana (Lea, 1834) in Sicily (Mollusca Bivalvia)

    ABSTRACT
    In this paper we report on the presence of two non-native and invasive species of bivalve mollusks in Sicily: Sinanodonta woodiana woodiana (Lea, 1834) (Bivalvia Unionidae) native to East Asia and Dreissena polymorpha (Pallas, 1771) (Bivalvia Dreissenidae) native to the Ponto-Caspian area, with a particular focus on how the presence of these alien species can lead to imbalances in the delicate equilibrium of Sicilian freshwater invertebrates and, above all, does threaten the existence of Unio elongatus gargottae Philippi, 1836 an island's native bivalve suffering from strong rarefaction.

    Molecular studies on the genus Medora H. et A. Adams, 1855 from Italy (Gastropoda Pulmonata Clausiliidae)

    ABSTRACT
    In Italy, the genus Medora H. et A. Adams, 1855 includes two species: M. italiana (Küster, 1847) and M. dalmatina (Rossmässler, 1835). In particular, populations ascribed to M. italiana were, and still are, the focus of several works aiming at better understanding the real taxonomic value of these entities and defining their presence on the Italian territory. In order to contribute to the improvement of the current knowledge on the organization of the genus at different taxonomic levels, several populations were investigated by analysing 16S rDNA, COI and ITS2 gene partial sequences. Phylogenetic reconstructions were obtained by the Maximum Likelihood algorithm. Although further studies are needed, preliminary data suggest that the genus Medora shows a much more complex and articulate differentiation than hypothesized so far.

    Molecular analysis of Muticaria syracusana and M. neuteboomi from Southeastern Sicily, Italy (Gastropoda, Pulmonata, Clausiliidae)

    ABSTRACT
    The genus Muticaria Lindholm, 1925, is currently distributed either in Southeastern Sicily or in the Maltese islands and comprises the species M. syracusana (Philippi, 1836), M. neuteboomi Beckmann, 1990 and M. macrostoma (Cantraine, 1835). For the first time, we report a molecular study on the topotypicous populations of M. syracusana and M. neuteboomi carried out on fragments of the ribosomal 16S rDNA subunit and the cytochrome oxydase I (COI) mitochondrial genes by Neighbour Joining, Maximum Likelihood, Maximum Parsimony and Bayesian Inference algorithms. Our results revealed the existence of nucleotide-sequence divergence (Dxy: 5% for 16S rDNA and 12% for COI sequences) between the two taxa.

    An annotated type catalogue of the land and freshwater mollusks from Tunisia and Libya in the Natural History Museum “Giacomo Doria” of Genova (Italy)
    https://doi.org/10.31396/Biodiv.Jour.2024.15.2.327.346

    ABSTRACT
    In the present work are listed the type specimens of land and freshwater molluscs from Tunisia and Libya deposited in the Natural History Museum “Giacomo Doria” of Genova (Italy). The historical nucleus of the malacological collections of the Museum of Genova is made up of the material collected by the young Giacomo Doria. After the official creation of the Museum in 1867, the malacological collection increased considerably in number of species and importance also through the material collected in various scientific missions organized by the Museum around the world. After 1916, the director Raffaello Gestro reorganized all this material and began the cataloging and selection of the type species. Nineteen nominal species described by Arturo Issel, Laura Gambetta, Jole Bisacchi and Rolf Arthur Max Brandt have been traced in these malacological collections. The type series described (types and syntypes) but also the material coming from the description localities and collected by the author himself (sometimes referred to as “topotypes”) were examined. For each taxa, the collection data obtained from the labels, the current taxonomic classification, the photographic documentation, remarks and the malacological bibliography are provided.
