Menemerus Zimbabwensis
''Menemerus zimbabwensis'' is a species of jumping spider in the genus ''Menemerus'' that lives in South Africa and Zimbabwe. The Polish arachnologist Wanda Wesołowska first described the female in 1999 and the male in 2007. The spider is large, with a cephalothorax that is between long and an abdomen that is between in length. The female is larger than the male. It also lacks the light stripe down the centre of its dark brown carapace and has a less distinct pattern on its abdomen. Its legs and pedipalps are yellow, while on the male they are brown. The male can be distinguished from the similar ''Menemerus nigli'' by the wide stripe on its abdomen. The female is harder to identify without looking at its copulatory organs. These are distinctive. It has characteristic large entrance bowls on its epigyne, which are larger than the insemination ducts and spermathecae combined. Its internal organs are very sclerotized.

Menemerus Nigli
''Menemerus nigli'' is a species of jumping spider in the genus ''Menemerus'' that originates in Asia. The male was identified in 2012 by Wanda Wesołowska and Mario Freudenschuss, and the female by Pir Asmat Ali, Wayne Maddison. Muhammad Zahid and Abida Buttin in 2018. The spider is medium-sized, typically in length, with a dark brown carapace and grey-brown abdomen that has a distinctive cream and white pattern created by small hairs. It was originally found in India, Pakistan and Thailand but was also found to have been introduced into Latin America, the first specimens being identified in Brazil in 2020. It seems to thrive amongst the sunlit stucco walls that are common in cities across the region. ''Menemerus nigli'' is used as an example of the ability of species that adapt to human habitation to expand their ecological niche and become global species. Taxonomy First described by Wanda Wesołowska and Mario Freudenschuss in 2012, the spider was allocated to the genus ''Men ...

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 ...

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, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

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] |
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.
