Paradonea Presleyi
''Paradonea presleyi'' is a species of araneomorph spiders in the family Eresidae. Distribution This species is found in Zimbabwe and South Africa. Description The male holotype has white setae concentrated in the thoracic and eye regions. The cephalic region is semicircular, wider than it is long, and moderately raised. The chelicerae are contiguous mesally, with a lateral boss. The legs have patches and longitudinal bands of white setae. Femur I is slightly thickened with a thick brush of dark setae; there are rows of distal ventral macrosetae on metatarsus I–IV, and a few scattered ventral macrosetae on tarsus I–IV and metatarsus II–IV. The dorsum of the abdomen has two longitudinal stripes of white hairs which are parallel anteriorly, diverge posteriorly, before connecting by transverse portion. The median part is medium brown, with the ectal and posterior parts being dark brown. The male palp have proximal-distal axis. The tegulum is subrectangular, and ...

Eresidae
Velvet spiders (family Eresidae) are a small group (about 130 species in 9 genera) of spiders almost entirely limited to the Old World, with exception of a few species known from Brazil. In Europe some are commonly called the ladybird spiders Description This family can sometimes be confused with the jumping spiders, or those in the Palpimanidae family. These spiders are usually black or brown in color, thought they can also have brighter colors as pictured. As their common name implies they can look quite smooth and velvety. They usually live in silken tubes under objects, or underground, but the genus '' Stegodyphus,'' builds silken nests. Identification They can be distinguished from most species except the Penestomidae by their semi rectangular carapace and clypeal hood. Thought the can be distinguished from Penestomidae by the eye arrangement, straight anterior eye row and strongly recurved posterior eye row, with the median eyes close together.

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

William Frederick Purcell
William Frederick Purcell (18 September 1866 - 3 October 1919) was an English-born South African arachnologist and zoologist. He is regarded as being the founder of modern araneology in South Africa. Early life and education Purcell was born in London, England to Dr Walter P.J. Purcell of Waterford, Ireland, and his wife Sophia W.J. Hertzog of Cape Town. In 1868 the family moved to South Africa and settled in Cape Town. He spent most of his childhood on the farm Bergvliet, which was owned by his uncle W.F. Hertzog. From 1881, Purcell studied at South African College, Cape Town, matriculated through the University of the Cape of Good Hope (UCGH) in 1884 and received a BA (with Honours) in mathematics and natural science in 1887 from UCGH. In 1885 and 1887 he provided the South African Museum with samples of ''coleoptera'' obtained at Bergvliet and Prieska. Purcell continued his education in Germany with a focus on the internal structure of arachnids. In 1894 Friedrich-Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This '' Atrax robustus'' shows the orientation of Myglamorphae fangs. Imag ...
