Pseudicius Unicus
''Spadera'' is a genus of jumping spiders containing the single species, ''Spadera unica''. It was first described by George and Elizabeth Peckham in 1894, and has only been found in Madagascar. Taxonomy First described in 1894, ''Spadera unica'' was transferred to ''Pseudicius'' by Eugène Simon in 1901. The genus ''Spadera'' remained sunk into ''Pseudicius'' until 2017, when Jerzy Prószyński reinstated ''Spadera unica''. Prószyński accepted that ''S. unica'' was similar to other members of his informal group "pseudiciines" (especially species of '' Rudakius''), but considered that there were sufficient differences, such as in the shape of the tibial apophysis of the palpal bulb, to retain a separate genus. The representative genus of Prószyński's "pseudiciines" is ''Pseudicius''. In Maddison's 2015 classification of the family Salticidae, ''Pseudicius'' is placed in the tribe Chrysillini, part of the Salticoida clade of the subfamily Salticinae Salticinae is a ...

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 ...

Salticidae
Jumping spiders are a group of spiders that constitute the 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 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 anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye pa ...

George And Elizabeth Peckham
George Williams Peckham (March 23, 1845 – January 10, 1914) and Elizabeth Maria Gifford Peckham (December 19, 1854 – February 11, 1940) were a married couple who were early American teachers, taxonomists, ethologists, arachnologists, and entomologists, specializing in animal behavior and in the study of jumping spiders (family Salticidae) and wasps. Lives and careers George Peckham was born in Albany, New York in 1845. At age 18, he enlisted in the U.S. Army to fight in the American Civil War, reaching the rank of first lieutenant. After the war, he resumed his studies, obtaining a law degree from Albany Law School in 1867. After graduation, George worked at the law office of James T. Brown of Milwaukee. Not caring for the law, however, he became a student in the medical college of the University of Michigan, earning his M.D. in 1872. Rather than practice medicine, however, he chose to teach biology at East Division High School of Milwaukee, Wisconsin. In 1 ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Pseudicius
''Pseudicius'' is a genus of the jumping spiders first described by Eugène Simon in 1885. The name is combined of Greek ''pseudo'' "false" and the salticid genus name ''Icius''. The small genus '' Wesolowskana'' (formerly known as ''Luxuria'') should possibly be included in this genus. There is some dispute whether ''Afraflacilla'' is a distinct genus or should be included in ''Pseudicius''. '' Festucula'' and ''Marchena'' are other close relatives, these genera form a monophyletic group. Species , the World Spider Catalog accepted the following species. Many species formerly placed here have been transferred to a variety of other genera. * '' Pseudicius adustus'' Wesołowska, 2006 – Namibia * '' Pseudicius africanus'' Peckham & Peckham, 1903 – South Africa, Lesotho * '' Pseudicius amicus'' Prószyński, 2000 – Middle East * '' Pseudicius andamanius'' ( Tikader, 1977) – Andaman Islands * '' Pseudicius athleta'' Wesołowska, 2011 – Uganda, Kenya * '' Pseudicius badius ...

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 ...

Jerzy Prószyński
Jerzy Prószyński (born 1935 in Warsaw) is a Polish arachnologist specializing in systematics of jumping spiders (family Salticidae). He is a graduate of the University of Warsaw, a long-term employee of the Siedlce University of Natural Sciences and Humanities and the Institute of Zoology of the Polish Academy of Sciences in Warsaw. Biography In 1957 he completed his biological studies at the University of Warsaw.

Rudakius
''Rudakius'' is a genus of spiders in the family Salticidae. It was first described in 2016 by Prószyński. , it contains 7 species. Taxonomy The genus ''Rudakius'' was one of a number of new genera erected by Jerzy Prószyński in 2016, largely for species formerly placed in ''Pseudicius''. Prószyński placed these genera in his informal group "pseudiciines", with ''Pseudicius'' as the representative genus. In Wayne Maddison's 2015 classification of the family Salticidae, ''Pseudicius'', broadly circumscribed, is placed in the tribe Chrysillini, part of the Salticoida clade of the subfamily Salticinae. Species ''Rudakius'' comprises the following species: * '' Rudakius afghanicus'' (Andreeva, Heciak & Prószyński, 1984) – Iran, Afghanistan Afghanistan, officially the Islamic Emirate of Afghanistan,; prs, امارت اسلامی افغانستان is a landlocked country located at the crossroads of Central Asia and South Asia.
