Italian specimens match those from Turkey and Spain in all shell shape and size features. Orculella, like several other components of the Italian land malacofauna (for example the helicoidean genera Monacha and Helix, the parmacellid slug Parmacella, etc.), has an eastern origin and presumably colonized the peninsula at the end of the Pliocene or later in the Pleistocene through the Alpine sector surviving up to the early Holocene

(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...

It is distinguished from all other anatomically studied limacid species: its duct of the bursa copulatrix joins to the female distal genitalia while in all other limacids except <i>Limacus flavus</i>, it joins to the penis (or the genital atrium). Several other features distinguish the Montecristo slug from <i>L. flavus</i>: body colour, structure of ovispermiduct and free oviduct (with a peculiar sphincter in the new slug), internal structure of the penis and female distal genitalia. Analysis of the nucleotide sequences of several mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) gene fragments supported the assignation of the Montecristo slug to the family Limacidae, but also its distinctio...

The structure of their apertural barrier (an angular lamella joined to the upper vertex of the peristome) matches that of species traditionally assigned to the nesopupines and among them recalls the monospecific Madeiran genus Staurodon. They are therefore assigned to a new species of this genus, S. cianfanellianus, although there is awareness that its classification is somewhat tentative due to taxonomic and systematic uncertainty and frequent character homoplasy in this group of land snails. If correct, this is the first finding of a nesopupine vertiginid in the European Pliocene, since members of this subfamily, currently distributed in tropical regions, are only known in the western Palaearctic from the Late Oligocene to the early Late Miocene. RIASSUNTO [Staurodon cianfanellianus n. sp. (Gastropoda Pulmonata Vertiginidae), un nuovo vertiginide ne...

These three species are assigned to 1xychilas (s.str.) sensu Grusrl & MANGANETLI (199D, a "subgenus" o{ Oxychilus characterized by penis with flagellum (1); penial retractor inserted at apex of flagellum (2); epiphallus long, usually more than proximal penis, its internal wall with slender longitudinal pleats (3); mucous gland mainly vaginal (4); Iong mesocone ofcentral tooth (5). The subgenus Alzonula Giusti, 1968a, established for O. oglasicola, is consequently regarded a a junior synonym of Oxycbilus (s.str.). O. nujori is distinguished by a small (shell diameter: 10.3 t 0.6 mm), discoidal, yellowish to pale brownish yellow shell and, anatomically, by extraordinary thickening ofthe penial sheath. 0. oglasicola is unmistakable by virtue ofits medium-sized (shell diame...

The records relate to twenty-six localities, sixteen of which are in the province of Siena, four in the province of Grosseto, two of Arezzo and one of Florence, Livorno, and Pisa respectively. Most of the localities (85% of cases) are located near wetlands as streams, rivers and lakes, from a minimum of 3 m to a maximum of 885 m above sea level. Since it is an uncommon species that lives in habitat in progressive alteration by humans, C. argiades is believed to be at risk in the long term in Tuscany

During its life, the society had 120 members (including four institutions) and published a journal, Bullettino della Società Malacologica Italiana. Between 1875 and 1899, 20 volumes were issued: papers mostly concerned Italian malacofauna. After almost 30 years this research line seemed to have dried up, and without generational turnover, the society dissolved between the end of 1906 and early 1907. A detailed survey of the organization, activities and membership provides an interesting picture of a malacological society in the late 1800s.

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 (Helixsobara Mabille, 1881, H.ardesa Mabille, 1881, H.apuanica Mabille, 1881, H.carfaniensis De Stefani, 1883 and H.spallanzanii De Stefani, 1884).
