Bursellia Gibbicervix
''Bursellia'' is a genus of African dwarf spiders that was first described by Å. Holm in 1962. Species it contains eight species and one subspecies: *'' Bursellia cameroonensis'' Bosmans & Jocqué, 1983 – Cameroon *'' Bursellia comata'' Holm, 1962 – Congo, Uganda **'' Bursellia c. kivuensis'' Holm, 1964 – Congo *'' Bursellia gibbicervix'' (Denis, 1962) – Tanzania *'' Bursellia glabra'' Holm, 1962 (type) – Congo, Kenya *'' Bursellia holmi'' Bosmans, 1977 – Kenya *'' Bursellia paghi'' Jocqué & Scharff, 1986 – Tanzania *'' Bursellia setifera'' (Denis, 1962) – Cameroon, Congo, Kenya, Tanzania, Malawi *'' Bursellia unicornis'' Bosmans, 1988 – Cameroon See also * List of Linyphiidae species File:Silometopus reussi (26805753808).jpg , Silometopus reussi File:Sheetweb Spider - Tapinopa bilineata, Woodbridge, Virginia.jpg , Tapinopa bilineata File:Araeoncus humilis.jpg, Araeoncus humilis Lists of Linyphiidae species cover species of t ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Linyphiidae
Linyphiidae, spiders commonly known as sheet weavers (from the shape of their webs), or money spiders (in the United Kingdom, Ireland, Australia, New Zealand, and Portugal) is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is '' Himalafurca'' from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided. Money spiders are known for drifting through the air via a technique termed " ballooning". Within the agriculture industry, money spiders are regarded as biological control agents against pest species like aphids and springtails. Description In Linyphiid ...
