Ambigolimax Valentianus Genitalia Cambridge
''Ambigolimax'' is a genus of air-breathing land slugs in the family Limacidae, the keelback slugs. There is still ongoing disagreement whether it is more appropriate to consider ''Ambigolimax'' as merely a subgenus of '' Lehmannia''; the evidence for splitting them is phylogenetic trees constructed on the basis of DNA sequences.

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 ...

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] |
Limacidae
Limacidae, also known by their common name the keelback slugs, are a taxonomic family of medium-sized to very large, air-breathing land slugs, terrestrial pulmonate gastropod molluscs in the superfamily Limacoidea. Distribution The distribution of the family Limacidae is the western Palearctic. There are 28 species of Limacidae in Russia and adjacent countries. Anatomy In this family, the number of haploid chromosomes lies between 21 and 25 and also lies between 31 and 35 (according to the values in this table).Barker G.

Ambigolimax Valentianus
''Ambigolimax valentianus'' (also known as ''Lehmannia valentiana'') is a species of air-breathing land slug, a terrestrial pulmonate gastropod The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda ().

Description '' External appearance does not reliably distinguish ''Ambigolimax valentianus'' from other members of the genus, such as ''Ambigolimax parvipenis, A. parvipenis'', with which it may co-occur. Like other members of the Limacidae, it has a pointed tail and the pneumostome lies in the posterior half of the mantle (mollusc), mantle. Often the most obvious character of an ''Ambigolimax'' slug is the two parallel, sharply defined, dark lines along the mantle, sometimes with a thicker less well defined line lying between.

Ambigolimax Parvipenis
''Ambigolimax parvipenis'' is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the Limacidae. Taxonomy ''Ambigolimax parvipenis'' was first clearly characterised in 2014, based on specimens from the British Isles. This work showed it to be distinct from the externally similar '' Ambigolimax valentianus'' on the basis both of genital anatomy and of the genetic sequences in the barcoding COI mitochondrial gene. The species later named ''Ambigolimax parvipenis'' was at that time referred to as ''Ambigolimax nyctelius'' (Bourguignat, 1861) because of some similarity in genital anatomy with a slug species from the Royal Botanic Garden Edinburgh that had been named ''Limax nyctelius'' or ''Lehmannia nyctelia'' (since renamed '' Ambigolimax waterstoni''). These two slug species both lack a penial appendage but differ considerably in the length of the penis. In 2022 it was shown that they are indeed different species, that they had both been confu ...

Ambigolimax Waterstoni
''Ambigolimax waterstoni'' is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Limacidae. Taxonomy This is one of the several species formerly confused under the name ''Limax nyctelius'' and later ''Lehmannia nyctelia'' or ''Ambigolimax nyctelius''. In the early 1930s A.R. Waterston wrote his undergraduate thesis describing a species of "''Limax''" from the Royal Botanic Garden Edinburgh. These specimens and others were the basis for H.E. Quick in 1946 to name them as ''Limax nyctelius'', a species described from Algeria. By that time M. Connolly had used this name for the same species in South Africa. It was subsequently reported more widely. Only in 2022 was it realised that these further findings were not all of the same species: slugs from the Carpathian Mountains and Bulgaria were of a species now called '' Lehmannia carpatica'' and the recently invasive species in Western Europe and California has been renamed ''Ambigolimax p ...

Ambigolimax Nyctelius
The name ''Ambigolimax nyctelius'' (and similarly ''Lehmannia nyctelia'' and ''Limax nyctelius'') has been used to refer to several species of air-breathing land slugs (terrestrial pulmonate gastropod molluscs) in the family Limacidae. An article published in 2022 revealed this confusion and furthermore showed that the original description applied to a slug species in a different family. The above names are therefore no longer appropriate and care is need to interpret the meaning of earlier usages. The following five species were confused: *''Letourneuxia nyctelia'' (family ''Arionidae'') is the slug originally described. Until 2022 it was mostly known as ''Letourneuxia numidica''; *'' Ambigolimax waterstoni'' is believed native in Algeria but has been reported also from South Africa, Australia, New Zealand, Elba and some Scottish botanic gardens; *''Ambigolimax parvipenis'' is a widespread invasive species in the British Isles and California, and has been reported also from Spai ...

Lehmannia Carpatica
''Lehmannia carpatica'' is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Limacidae. Taxonomy When Grossu & Lupu (1963) first noted this species, in Romania, its long penis and lack of penial appendage led it to be confused with ''Ambigolimax waterstoni'', which at that time was incorrectly named as ''Limax nyctelius''; the later renamings as ''Lehmannia nyctelia'' or ''Ambigolimax nyctelius'' remained incorrect. Only in 2022 was the confusion recognised, requiring both ''A. waterstoni'' and ''L. carpatica'' to be formally described as distinct species. The same article described a third species, ''Ambigolimax parvipenis'' that had also been called ''Lehmannia nyctelia'' and confused with the other two; the article further pointed out that the original name ''Limax nyctelius'' referred to a species of ''Letourneuxia''. ''Lehmannia carpatica'' had also been misidentified as ''Mesolimax braunii'' in an article published in 1898. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
