    New report of Aperiovula juanjosensii Pérez et Gómez, 1987 (Gastropoda Ovulidae) for the Sicilian coast

    ABSTRACT
    One living specimen of Aperiovula juanjosensii Pérez et Gómez, 1987 (Gastropoda Ovulidae) was found in the Strait of Messina (North-East Sicily), at Punta Faro at a depth of about 90 m. The specimen was found in the fishing rest, in a sample rich of Myriapora truncata (Pallas, 1776), but with presence of Paramuricea clavata (Risso, 1826) and Eunicella cavolinii (Esper, 1791). The gorgonian Villogorgia bebrycoides (Koch, 1887), indicated as host in literature, even if should be present in the area, has not been found. A. juanjosensii was described for the area of Canary Islands and Atlantic Marocco and, up to now, only shown for a location of the Italian coast, without additional data.

    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.

    On the specific validity of Rupestrella jaeckeli Beckmann, 2002 (Gastropoda, Pulmonata, Chondrinidae)

    ABSTRACT
    After studying the shells of a large population of Rupestrella jaeckeli Beckmann, 2002, located ESE of Agrigento (southern Sicily), near the type locality, a complete correspondence of characters with Rupestrella philippii (Cantraine, 1840) was observed; the latter has already been known to occur in central-eastern Sicily as well as other Mediterranean areas. Synonymy is therefore proposed between the two taxa: R. jaeckeli should be more properly considered a junior synonym of R. philippii.

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

    ABSTRACT
    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.

    ABSTRACT
    Two new Marginellidae species are described from Callao, Peru, and placed into the genus Prunum Herrmannsen, 1852, as P. sigmoides n. sp. and P. lamellosum n. sp. The reliability of the locality attributed to these new species is discussed, and the two species are considered to come with high probability from Western South America, due to their original features not matching Prunum morphs known from the rest of the Panamic Province, Caribbean or West Africa.
