Menemerus Patellaris
''Menemerus patellaris'' is a species of jumping spider in the genus ''Menemerus'' that lives in Yemen. The spider was first described in 2007 by Wanda Wesołowska and Antonius van Harten. The spider is medium-sized with a carapace that is typically long and abdomen between long. The carapace is brown with white stripes on the edges. The abdomen is yellowish-beige, while the legs are yellow. The spider is hard to distinguish from others in the genus without a study of its copulatory organs. It has a very short embolus and a distinctive furrow in its tegulum dividing a sac of tissue used in copulation called the haematodocha. In addition to the spike, or apophysis on its tibia, it has another one on the patellar, the section between the tibia and the palpal bulb. Taxonomy ''Menemerus patellaris'' is a species of jumping spider that was first described by Wanda Wesołowska and Antonius van Harten in 2010. It is one of over 500 species identified by the Polish arachnologist Weso ... [...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 phylogene ...

Clade (biology)
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organis ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics (synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have take ...

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, 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 Open source is source code that is made freely available for possible modification and redistribution.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Goat-antelope#Tribe Caprini, Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Scilloideae#Hyacintheae, Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form ...

Helvetia
Helvetia () is the female national personification of Switzerland, officially ''Confoederatio Helvetica,'' the Swiss Confederation. The allegory is typically pictured in a flowing gown, with a spear and a shield emblazoned with the Swiss flag, and commonly with braided hair, commonly with a wreath as a symbol of confederation. The name is a derivation of the ethnonym '' Helvetii'', the name of the Gaulish tribe inhabiting the Swiss Plateau before the Roman conquest. History The fashion of depicting the Swiss Confederacy in terms of female allegories arises in the 17th century. This replaces an earlier convention, popular in the 1580s, of representing Switzerland as a bull (''Schweizer Stier''). In the first half of the 17th century, there was not a single allegory identified as ''Helvetia''. Rather, a number of allegories were shown, representing both virtues and vices of the confederacy. On the title page of his 1642 ''Topographia'', Matthäus Merian shows two allego ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
