Menemerus Transvaalicus
''Menemerus transvaalicus'' is a species of jumping spider in the genus ''Menemerus'' that lives in Lesotho and South Africa. The species was first identified in 1999 by Wanda Wesołowska, one of over 500 descriptions she has written during her lifetime. The spider often lives on ''Eucalyptus'' trees and the walls of buildings. It is small, with a dark brown hairy carapace that is between long and a fawn to dark brown abdomen that is between in length. The female is larger than the male. It has a yellowish leaf-shaped pattern on its abdomen and orange to brown legs. The male has a conductor on its double embolus, which helps to distinguish the spider from the related ''Menemerus bifurcus''. Taxonomy ''Menemerus transvaalicus'' is a species of jumping spider that was first described by Wanda Wesołowska in 1999. It was one of over 500 species identified by the Polish arachnologist during her career, making her one of the most prolific in the field. She allocated the spider to the ...

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 ...

Spider Vision
The eyes of spiders vary significantly in their structure, arrangement, and function. They usually have eight, each being a simple eye with a single lens (optics), lens rather than multiple units as in the compound eyes of insects. The specific arrangement and structure of the eyes is one of the features used in the identification and classification of different species, genera, and families. Most Haplogynae, haplogynes have six eyes, although some have eight (Plectreuridae), four (e.g., ''Tetrablemma'') or even two (most Caponiidae). In some cave species, there are no eyes at all (e.g. Stalita taenaria). Sometimes one pair of eyes is better developed than the rest. Several families of hunting spiders, such as jumping spiders and wolf spiders, have fair to excellent vision. The main pair of eyes in jumping spiders even sees in colour. Structure and anatomy Spiders' eyes are Simple eye in invertebrates, simple eyes, or ''ocelli'' (singular ''ocellus''), meaning their eyes have a si ...

Transvaal (province)
The Province of the Transvaal ( af, Provinsie van Transvaal), commonly referred to as the Transvaal (; ), was a province of South Africa from 1910 until 1994, when a new constitution subdivided it following the end of apartheid. The name "Transvaal" refers to the province's geographical location to the north of the Vaal River. Its capital was Pretoria, which was also the country's executive capital. History In 1910, four British colonies united to form the Union of South Africa. The Transvaal Colony, which had been formed out of the bulk of the old South African Republic after the Second Boer War, became the Transvaal Province in the new union. Half a century later, in 1961, the union ceased to be part of the Commonwealth of Nations and became the Republic of South Africa. The PWV (Pretoria-Witwatersrand-Vereeniging) conurbation in the Transvaal, centred on Pretoria and Johannesburg, became South Africa's economic powerhouse, a position it still holds today as Gauteng Provinc ...

Provinces Of South Africa
South Africa is divided into nine provinces. On the eve of the 1994 South African general election, 1994 general election, South Africa's former homelands, also known as Bantustans, were reintegrated, and the four existing provinces were divided into nine. The twelfth, thirteenth and sixteenth amendments to the Constitution of South Africa changed the borders of seven of the provinces. History The Union of South Africa was established in 1910 by combining four British colonies: the Cape Colony, the Natal Colony, the Transvaal Colony and the Orange River Colony (the latter two were, before the Second Boer War, independent republics known as the South African Republic and the Orange Free State). These colonies became the four original provinces of the Union: Cape Province, Transvaal Province, Natal Province and Orange Free State Province. Segregation of the black people, black population started as early as 1913, with ownership of land by the black majority being restricted to ...

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. 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.
