Molecular phylogenetic relationships among 45 members of the Helicoidea (Gastropoda: Stylommatophora) were examined using partial mitochondrial 16S rRNA sequences. Phylogenetic relationships were inferred using maximum parsimony, maximum likelihood and Bayesian methods. The reconstructed phylogenies showed a good degree of support for more recent branches, but gave little support to deeper nodes. Mitochondrial rDNA data further confirmed monophyletic status of helicids, recognized monachine hygromiid and bradybaenid clades and resolved a number of relationships in the helicelline hygromiids. With the respect to the latter assemblage, most of the anatomically based groups are confirmed, corroborating the diagnostic value of the dart-sac complex and a close affinity between Ichnusomunda sacchii and species of the genus Cernuella. Nevertheless, some well resolved branches challenge previous systematic arrangements, grouping species previously placed in different arrangements. In particular, support was not found for the monophyly of helicelline hygromiids with pedal penial innervation. Possible explanations for these incongruencies are suggested. 16S sequence data are appropriate for studies of relationships within the different species groups and less so for recovery of more ancient radiations in the Helicoidea. It will be valuable to combine the 16S data with other gene sequences to estimate basal relationships. 12 pp., 3 figs, 4.…

Anatomical study of specimens of the type species of Avenionia, Avenionia vayssieri Nicolas, 1882 (junior synonym of Paulia berenguieri Bourguignat, 1882, currently A. brevis berenguieri), from southern France, revealed characters different from those known in the available literature and prompted the redefinition of Avenionia. The other Avenionia species from France and nearby countries of central-western Europe are tentatively left in this genus, whereas taxa from Italy which were included in Avenionia on formerly available evidence will be to be assigned to another genus. 12 pp., 27 figs, gr. 8.…

Morphological data shows that O. paulucciae (De Stefani, 1883) belongs to Oxychilus (s. str.), sensu Giusti & Manganelli (1999), and is distinguished from sympatric, similarly shelled species, such as O. draparnaudi (Beck, 1837) and O. meridionalis (Paulucci, 1881), by its larger shell (diameter: 13.9-17.4 mm), smaller umbilicus (about 1/8 of shell diameter), narrow mid-penial region, internal ornamentation of proximal penis consisting of longitudinal pleats, and a less developed vaginal gland, often forming an incomplete ring around proximal vagina. DNA sequence data, analysing the ITS-1 region in two specimens of O. paulucciae and representatives of several other species occurring in Tuscany, O. draparnaudi, O. majori (Paulucci, 1886), O. meridionalis, O. pilula (Paulucci, 1886) and O. uzielli (Issel, 1873), indicates that O. paulucciae represents a well-differentiated evolutionary lineage and suggests it has close relationships with O. meridionalis and O. uziellii. Finally, analysis of morphological characters and DNA sequencing data demonstrates that Oxychilus lanzai Forcart, 1967, is a junior synonym of O. paulucciae. 17 pp., 15 figs, gr. 8. …

The taxonomic and nomenclatural status of Oxychilus adamii (Westerlund, 1886) and O. polygyra (Pollonera, 1885) is revised. These two, very similar species are tentatively assigned to Mediterranean a 'subgenus' of Oxychilus characterized by (1) absent or very short flagellum; (2) penial retractor inserted where epiphallus ends and proximal penis begins; (3) internal ornamentation of penis consisting of pleats and rows of papillae, some of which or all with apical thorn; (4) short epiphallus internally with series of transverse crests on one side and a few slender longitudinal pleats on the other; (5) mucous gland forming muff of glandular tissue, denser and yellower around distal portion of free oviduct; (6) and short mesocone on the central tooth. O. adamii is distinguished by a medium-sized shell (diameter 16.1 ± 1.0 mm) and very small papillae without apical thorn covering the initial portion of the proximal penis. O. polygyra is distinguished by a small shell (diameter 10.4 ± 0.5 mm) and large papillae with an evident cuticularized apical thorn covering the initial portion of the proximal penis. The paper concludes with a review of the current status of Oxychilus taxonomy, including the main problems and some tentative solutions to be verified in the context of individual revisions. 34 pp., 33 figs, gr. 8.…

Two new lineages CAN-5 and CAN-6 were recognised in four populations of Monacha cantiana (Montagu, 1803) s.l. from the Italian Apuan Alps by joint molecular and morphological analysis. They are different from other M. cantiana lineages known from English, Italian, Austrian and French populations, i.e. CAN-1, CAN-2, CAN-3 and CAN-4, as well as from the other Italian Monacha species used for comparisons (M. parumcincta and M. cartusiana). Although a definite taxonomic and nomenclatural setting seems to be premature, we suggest that the name or names for these new lineages as one or two species should be found among 19th century names (Helix sobara Mabille, 1881, H. ardesa Mabille, 1881, H. apuanica Mabille, 1881, H. carfaniensis De Stefani, 1883 and H. spallanzanii De Stefani, 1884). pp. 115-149, gr. 8. …

Specimens obtained from ten populations of a Monacha species from the central Apennines were compared with six molecular lineages of Monacha cantiana s. l. (CAN-1, CAN-2, CAN-3, CAN-4, CAN-5, CAN-6) and two other Monacha species (M. cartusiana and M. parumcincta), treated as outgroup, by molecular (nucleotide sequences of two mitochondrial COI and 16S rDNA as well as two nuclear ITS2 and H3 gene fragments) and morphological (shell and genital anatomy) analysis. The results strongly suggest that these populations represent a separate species for which two names are available: the older Helix pantanellii De Stefani, 1879 and the junior M. ruffoi Giusti, 1973. The nucleotide sequences created well separated clades on each phylogenetic tree. Genital anatomy included several distinctive features concerning vaginal appendix, penis, penial papilla and flagellum; instead, shell characters only enabled them to be distinguished from M. cartusiana and M. parumcincta. Remarkably, populations of M. pantanellii show high morphological variability. Shell variability mainly concerns size, some populations having very small dimensions. Genital variability shows a more intricate pattern of all anatomical parts, being higher as regards the vagina and vaginal appendix. Despite this morphological variability, the K2P distance range of COI sequences between populations is narrow (0.24.5%), if we consider all but three of the 53 sequences obtained. This research confirmed that the species of Monacha and their molecularly distinguished lineages can only occasionally be recognised morphologically and that they have significant inter- and intra-population variability. The possibility of using an overall approach, including shell, genital and molecular evidence, was taken in order to establish a reliable taxonomic setting. 45 pp., 68 figs, gr. 8 [16.5 x 24 cm].…

Questo lavoro riporta i risultati di uno studio sulla malacofauna della Valle di Susa condotto sia sui dati storici disponibili (bibliografici e museali), sia su dati inediti frutto di nuove ricerche effettuate tra il 1997 e 2006. Nell'area sono state accertata 159 specie di molluschi (121 terrestri e 38 d'acqua dolce), ciascuna delle quali è descritta ed illustrata in un'apposita scheda. L'alto numero de specie di molluschi viventi nel territorio valsusinoè sicuramente collegato alla posizione geografica della valle, al suo sviluppo longitudinale e altimetrico alla sua diversità litologica, climatica e vegetazionale. This work reports the results of a study on the malacofauna of the Susa Valley conducted both on available historical data (bibliographic and museum data), and on unpublished data resulting from new research carried out between 1997 and 2006. In the area 159 species of molluscs (121 terrestrial and 38 freshwater), each of which is described and illustrated in a special chapter. The high number of species of molluscs living in the Susa Valley area is certainly linked to the geographical position of the valley, to its longitudinal and altimetric development, to its lithological, climatic and vegetational diversity.
