Araneus
''Araneus'' is a genus of common orb-weaving spiders. It includes about 650 species, among which are the European garden spider and the barn spider. The genus was erected by Carl Alexander Clerck in 1757. Description Spiders of this genus present perhaps the most obvious case of sexual dimorphism among all of the orb-weaver family, with males being normally to the size of females. In ''A. diadematus'', for example, last-molt females can reach the body size up to 1 in (2.5 cm), while most males seldom grow over 0.3 in (1 cm), both excluding leg span. Males are differentiated from females by a much smaller and more elongated abdomen, longer legs, and the inability to catch or consume prey bigger than themselves. In females, the epigyne has a long scape (a tongue-like appendage). Male pedipalps have a hook-like terminal apophysis. Abdominal tubercles are present anterolaterally. Taxonomic history ''Araneus'' was, for much of its history, called ''Epeira''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Svenska Spindlar
The book ' or ' (Swedish and Latin, respectively, for "Swedish spiders") is one of the major works of the Swedish arachnologist and entomologist Carl Alexander Clerck and was first published in Stockholm in the year 1757. It was the first comprehensive book on the spiders of Sweden and one of the first regional monographs of a group of animals worldwide. The full title of the work is '' – '', ("Swedish spiders into their main genera separated, and as sixty and a few particular species described and with illuminated figures illustrated") and included 162 pages of text (eight pages were unpaginated) and six colour plates. It was published in Swedish, with a Latin translation printed in a slightly smaller font below the Swedish text. Clerck described in detail 67 species of Swedish spiders, and for the first time in a zoological work consistently applied binomial nomenclature as proposed by Carl Linnaeus. Linnaeus had originally invented this system for botanical names in his 1753 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philodromus
''Philodromus'' is a genus of philodromid crab spiders. Spiders in this genus are distinctively flattened. The more than 250 described species are distributed throughout the Holarctic region, with few species reaching into more southern regions. Some are found in certain parts of Africa, with sporadic species occurring up to Australia. Only one species (''P. traviatus'') is found in (northern) South America. 16 species occur in Central Europe. Species Selected examples of ''Philodromus'' species: * '' P. aureolus'' * '' P. cespitum'' * '' P. dispar'' * '' P. fallax'' * '' P. margaritatus'' * '' P. rufus'' * '' P. rufus vibrans'' * '' P. vulgaris'' Dubious names '' Nomina dubia'' (dubious names) include: *''Philodromus depriesteri'' (Braun, 1965) *''Philodromus micans'' (Menge, 1875) Gallery Philodromus margaritatus.ogv, ''Philodromus margaritatus'' Metallic Crab Spider - Philodromus marxi, Leesylvania State Park, Woodbridge, Virginia.jpg, Male metallic crab spider ( ...

Spiders Described In 1757
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Taxa Named By Carl Alexander Clerck
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
