    A new record for the Italian fauna: Plagyrona placida (Shuttleworth, 1852) from Sardinia and Southern Italy (Gastropoda Pulmonata Valloniidae)

    ABSTRACT
    Plagyrona placida (Shuttleworth, 1852) is a terrestrial minute species with a wide but fragmented distribution, known from some of the Macaronesian Islands of the Canaries and the Madeira archipelago, from Corsica Island, from some European countries (Portugal, Albania and Greece) and from Northern Africa (Algeria). This species has been recently discovered in Italy (Sardinia, Campania and Calabria) for the first time; data of sampling and the characteristics of the Italian populations are discussed in this note. P. placida lives in the Mediterranean forest or bush environments, but its specific habitat is not known because it has been found, at least in Italy, in alluvial debris collected along streams and in litter. Even if this species has not been recorded until now, the undisturbed habitat and its rarity suggest that it may be native to Italy, and not accidentally introduced by man through trees used for reforestation or through imported vegetables, as already happened for others small species.

    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.

    ABSTRACT
    Two new taxa belonging to the genus Acicula Hartmann, 1821, are described: A. giglioi n. sp., endemic from the Nebrodi Chain (north Sicily), and A. giglioi peloritana n. ssp., endemic from Peloritani Ridge (north-eastern Sicily). Their shells are characterized by the shape of the peristome: flattend, well separated from the last whorl of the spire, arched in lateral view and more or less strongly turned backwards in its upper part, crossed by several superficial striae. The two subspecific taxa differ from each other in the different character of the shell (height and diameter of shell, ratio H/D, number of striae in the penultimate whorl) and their distribution (Nebrodi and Peloritani mountains respectively). In addition, Acicula szigethyannae Subai, 1977 (Gastropoda Aciculidae), already known in peninsular Italy (from eastern Liguria to southern Calabria) and in eastern Sicily, is now confirmed as present in all central-eastern Sicily.
