Pellenes Geniculatus
''Pellenes geniculatus'' is a jumping spider species in the genus ''Pellenes''. First named ''Attus geniculatus'' by Eugène Simon in 1868, it was given its current name by Simon in 1876. A small spider, between long, it has a large range that stretches across Southern Europe, Africa and Central Asia. There is some variation between those found in Africa and in Europe and Asia, the former generally being slightly smaller. The head has a distinctive pattern of lines formed of white scales. Taxonomy Originally allocated to the genus '' Attus'', the species was first identified by Eugène Simon in 1868. The original description was solely of the female, and the male was misidentified as a new species, ''Attus gemellus'', when first described by Simon in 1873. The current name was given by Simon in 1876 when the two were recognised as the same species. In 1987, it was recognised that ''Pellenes kraepelinorum'' described the same species, and so this became a synonym, as did ''Pell ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in his ...

Ekaterina Andreeva (arachnologist)
Ekaterina Mikhailovna Andreeva also known as Katarzyna Andrejewa-Prószyńska (16 November 1941 – 18 September 2008) was an Uzbek arachnologist. She collected spiders in Central Asia and later published ''Spiders of Tajikistan''. At least eight spider and harvestman taxa were named in her honor. Life Andreeva was born on 16 November 1941 in Tashkent (the current capital of Uzbekistan) and spent some of her childhood in Samarkand. Her grandmother, Maria Vikentievna Jasiewicz, was Polish, but had been exiled to Central Asia in the late 1880s for her political activity, and there married a land surveyor Konstantin Pisarczik, and had four children, including Andreeva's mother, Antonina Konstantinovna. Antonina became a student of ethnography at Tashkent University, and later married a professor of ethnography from the university, Mikhail Stepanovich Andreev. Their daughter Ekaterina Andreeva was born in Tashkent in 1941, and in 1946 moved with her mother to Dushanbe in Tajikista ...

Jumping Spider
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pellenes
''Pellenes'' is a genus of jumping spiders that was first described by Eugène Louis Simon in 1876. It is considered a senior synonym of ''Hyllothyene''. They are dark to black with white stripes on the back, and often have bright red markings. Most species have a special propensity for snail shells. ''Pellenes seriatus'' and ''P. lapponicus'' males look very similar to ''Hasarius adansoni'' when viewed from the front. Species it contains eighty-three species and one subspecies, found in North America, Africa, Europe, Asia, Australia, and on Saint Helena: *'' P. aethiopicus'' Strand, 1906 – Ethiopia *'' P. albopilosus'' (Tyschchenko, 1965) – Russia, Kazakhstan *'' P. allegrii'' Caporiacco, 1935 – Ukraine, Russia (Europe) to Central Asia *'' P. amazonka'' Logunov, Marusik & Rakov, 1999 – Central Asia *'' P. apacheus'' Lowrie & Gertsch, 1955 – USA *'' P. arciger'' (Walckenaer, 1837) – Southern Europe, Armenia *'' P. badkhyzicus'' Logunov, Marusik & Rakov, 1999 – Tur ...

Species Distribution
Species distribution —or species dispersion — is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density. Range In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density. Range is often described with the following qualities: * Sometimes a distinction is made betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attus
''Attus'' is a taxon name that is now considered a junior synonym of '' Salticus''. In the early 19th century, most jumping spiders were grouped together as a single genus under the name ''Attus''. The genus was originally described in 1805 by Charles Walckenaer, only a year after Pierre Latreille described the first jumping spider genus (or subgenus), ''Salticus''. Walckenaer, ignoring Latreille, placed all of the spiders assigned to ''Salticus'' into his new genus, ''Attus'', with the exception of '' Aranea cinnaberinus'', which he placed into ''Eresus''. No further actions were taken regarding these genera until 1810, when Latreille moved '' Attus scenicus'' back to ''Salticus'' by declaring it as the type species for the genus. Over the course of the 19th century, numerous new genera were split off of ''Attus'', reducing the number of species assigned to the genus considerably. In 1832, Nicholas Marcellus Hentz detached the genera '' Lyssomanes'', ''Synemosyna'', and '' Epib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Spiders Described In 1868
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 ...
