Nepalicius Nepalicus
''Nepalicius'' is a genus of spiders in the family Salticidae. It was first described in 2016 by Prószyński. , it contains 3 species. Taxonomy The genus ''Nepalicius'' 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 Salticinae is a subfamily of jumping spiders (family Salticidae).

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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. During his studies he was employed at the Institute of Zoology of the Polish Academy of Sciences in Warsaw, where he conducted research on spiders in the Kampinos Forest. Between 1963 and 1967 he lectured on zoology at the University of Ghana. In 1966 he obtained his Ph.D. at the Adam Mickiewicz University in Poznań. A year later he was given the opportunity to pursue a postdoctoral fellowship at Harvard University, but he was refused a passport. In 1972 he was employed at the Higher School of Education in Siedlce (later the Siedlce University of Natural Scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Wayne Maddison
Wayne Paul Maddison , is a professor and Canada Research Chair at the departments of zoology and botany at the University of British Columbia, and the Director of the Spencer Entomological Collection at the Beaty Biodiversity Museum. His research concerns the phylogeny, biodiversity, and evolution of jumping spiders (Salticidae), of which he has discovered new species and genera. He has also done research in phylogenetic theory, developing and perfecting various methods used in comparative biology, such as character state inference in internal nodes through Maximum parsimony (phylogenetics), maximum parsimony, squared-change parsimony, or character correlation through the concentrated changes test or pairwise comparisons. In collaboration with David R. Maddison, he worked on thMesquiteopen-source phylogeny software, thMacCladeprogram, and the Tree of Life Web Project. His research has led him to discover new species of jumping spiders in Sarawak and Papua New Guinea. Selected pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Salticoida
Salticoida is an unranked clade of the jumping spider family Salticidae. It is the larger and more widespread of the two subdivisions of the "typical" jumping spiders (subfamily Salticinae), occurring effectively world-wide. Its sister clade is Amycoida, which is also very diverse ecologically but has a mostly South American distribution. Systematics and evolution Salticoida includes the bulk of extant jumping spider diversity, with over 400 genera organized phylogenetically into 18 tribes according to Wayne Maddison's 2015 proposal. The age and origin of the Salticoida are not well determined. Certainly, by the late Paleogene the major lineages were recognizably distinct as indicated by the fossil evidence and molecular phylogeny. Thus, the salticoids presumably originated during or around the PETM or a bit earlier, but no corresponding fossils have been found yet. Their sister lineage, the Amycoida, probably originated by dispersal across the ocean to South America, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salticinae
Salticinae is a subfamily of jumping spiders (family Salticidae). It includes over 90% of the known species of jumping spiders. The subfamily is divided into two unranked clades: Amycoida and Salticoida. Description Members of the subfamily Salticinae have a number of features in common that distinguish them from the remaining salticids. Females lack a tarsal claw on the pedipalp. The palpal bulb of male basal salticids has a distinctive median apophysis, which is absent in the subfamily, and the cymbium is constricted at the tibial joint. Members also have a more complex tracheal system, which may be connected with their movements, which are more abrupt than other salticids, giving them a recognizable gait. Taxonomy Phylogeny The relationships among the basal salticids are not yet fully resolved; summary cladograms published in both 2014 and 2015 show unresolved branching for five basal subfamilies. However, Hisponinae is resolved as sister to Salticinae, which is the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wanda Wesołowska
Wanda Wesołowska (born 11 August 1950) is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s. She subsequently undertook study into the genus ''Heliophanus'' at the University of Wroclaw. Her subsequent doctoral thesis described 44 new species, and joined the staff at the university. She stayed until retiring in 2020. Her research included the taxonomy and zoogeography of jumping spiders, and has included extensive work on African genera like ''Menemerus'' and ''Pachyballus''. She has identified over 500 species, including half of all those from South Africa, as well as having more than 20 named after her. Early life Wanda Wesołowska (née Nowysz) was ...
