Ariunculus
''Ariunculus'' is a genus of air-breathing land slugs in the family Arionidae, the roundback slugs. Sometimes it has been considered as a subgenus of ''Arion'', and sometimes the subgenus ''Ichnusarion'' has been raised to generic rank. Etymology The stem of ''Arion'' plus the suffix -unculus, which is a diminutive in Latin. Hence "little ''Arion''". Pollonera justifies why "Ariunculus" is appropriate rather than "Arionculus" (cf. "homo" and "homunculus"). The subgenus name ''Ichnusarion'' is also based on "''Arion''", to which has been added "Ichnusa", a Latin name of Sardinia, where the single species of this subgenus is endemic. Species Only two species are currently recognised: subgenus ''Ariuncululus'' * '' Ariunculus speziae'' Lessona, 1881 – type species of the genus; Italian Alps with one record in Switzerland subgenus ''Ichnusarion'' Pollonera, 1890 * '' Ariunculus isselii'' Lessona & Pollonera, 1882 – Sardinia Other species have been discounted as d ...

Ariunculus Isselii
''Ariunculus isselii'' is a species of terrestrial slug belonging to the family Arionidae. Previously it has been placed in the genus ''Arion'' or in its own genus ''Ichnusarion''; the latter is more often treated as a subgenus. The species is restricted to the island of Sardinia, but widespread there, from sea level to at least 1400 m. Its length crawling can approach 10 cm. Superficially it looks like other large slugs in the related genus ''Arion'', with the pneumostome in the front part of the mantle; its coloration is olive-grey with bright yellow pigment granules superimposed. Unlike species in the arionid genera ''Arion'' and'' Geomalacus ''Geomalacus'' is a genus of large air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Arionidae, the roundback slugs.

Mario Lessona
Mario Lessona (18 December 1855 in Genoa – 25 December 1911 in Turin) was an Italian zoologist and malacologist. He was the son of the prominent natural scientist and senator Michele Lessona and his wife Adele Masi Lessona, who was very much involved in her husband's work, particularly in making translations. A son of Adele Lessona by an earlier marriage was the painter and malacologist Carlo Pollonera, with whom Mario published a monograph on Italian slugs. Mario also coauthored various scientific works with his brother-in-law, the zoologist and senator Lorenzo Camerano. Biography In the 1880s, Lessona was an assistant professor of zoology at the University of Messina, and then a teacher of natural history at secondary schools in Venice and Carmagnola. In the 1890s he worked as a teacher in the Fornaris-Morocco boarding school in Turin. He published on malacology and comparative anatomy, as well as writing several books of natural history and geography for schools. He also edit ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Slug
Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word ''slug'' is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs (this is in contrast to the common name ''snail'', which applies to gastropods that have a coiled shell large enough that they can fully retract their soft parts into it). Various taxonomic families of land slugs form part of several quite different evolutionary lineages, which also include snails. Thus, the various families of slugs are not closely related, despite a superficial similarity in the overall body form. The shell-less condition has arisen many times independently as an example of convergent evolution, and thus the category "slug" is polyphyletic. Taxonomy Of the six orders of Pulmonata, two – the Onchidiacea and Soleolifera – solely comprise slugs. A third family, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arion (gastropod)
''Arion'' is a genus of air-breathing land slugs in the family Arionidae, the roundback slugs. Most species of this Palearctic genus are native to the Iberian Peninsula. Species can be difficult to distinguish from one another upon cursory examination, because individuals of a species can vary in color and there are few obvious differences between taxa. The color of an individual can be influenced by its diet.Jordaens, K., et al. (2001)Food-induced body pigmentation questions the taxonomic value of colour in the self-fertilizing slug ''Carinarion'' spp.''Journal of Molluscan Studies'' 67(2), 161-67. Some ''Arion'' are known as pests, such as ''A. lusitanicus'' auct. non Mabille (= ''A. vulgaris''), which damages agricultural crops and ornamental plants, and ''A. rufus'', a familiar garden pest. ''Arion'' slugs are often transported internationally in shipments of plant products and mushrooms. ''Arion'' slugs have been identified in North America and Australia as invasive species, ...

Sardinia
Sardinia ( ; it, Sardegna, label=Italian, Corsican and Tabarchino ; sc, Sardigna , sdc, Sardhigna; french: Sardaigne; sdn, Saldigna; ca, Sardenya, label=Algherese and Catalan) is the second-largest island in the Mediterranean Sea, after Sicily, and one of the 20 regions of Italy. It is located west of the Italian Peninsula, north of Tunisia and immediately south of the French island of Corsica. It is one of the five Italian regions with some degree of domestic autonomy being granted by a special statute. Its official name, Autonomous Region of Sardinia, is bilingual in Italian and Sardinian: / . It is divided into four provinces and a metropolitan city. The capital of the region of Sardinia — and its largest city — is Cagliari. Sardinia's indigenous language and Algherese Catalan are referred to by both the regional and national law as two of Italy's twelve officially recognized linguistic minorities, albeit gravely endangered, while the regional law provides ...

Carlo Pollonera
Carlo Pollonera (Alexandria, Egypt, March 27, 1849 – Turin, June 17, 1923) was an Italian painter, particularly of landscapes, and also an important malacologist. Biography Carlo Pollonera's father, Giovanni B. Pollonera, was a lawyer in Alexandria. He died when Carlo was a child, after which his mother returned to Italy (Genoa) and remarried. As a seventeen-year-old, Carlo fought with Garibaldi on the Trentino campaign of 1866. In 1865, the family had moved to Turin, where Pollonera began studying painting with Alberto Maso Gilli. He enrolled at the Accademia Albertina and studied under Gamba and Andrea Gastaldi. Pollonera was a rebellious pupil, wanting to paint exactly what he saw, rather than, for instance, changing a distracting background. This principle not to improve on what he saw remained a hallmark of his painting throughout Pollonera's career. After four years with Gastaldi, in 1873 he switched to study in the private school of Antonio Fontanesi. In January 1875, he ...
