Dictynidae
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant. The genus '' Argyroneta'' has been placed in a separate family Argyronetidae, but the family is not accepted by the World Spider Catalog and the genus is included in the Dictynidae. Genera , the World Spider Catalog accepts the following genera: *'' Adenodictyna'' Ono, 2008 — Japan *''Aebutina'' Simon, 1892 — Ecuador, Brazil *''Ajmonia'' Caporiacco, 1934 — Asia, Algeria *''Altella'' Simon, 1884 — Europe, Asia, Algeria *'' Anaxibia'' Thorell, 1898 — Asia, Africa *''Arangina'' Lehtinen, 1967 — New Zealand *'' Archaeodictyna'' Caporiacco, 1928 — Asia, Europe, Africa *''Arctella'' Holm, 1945 — Asia, North America *'' Argenna'' Thorell, 1870 — Asia, North America *'' Argennina'' Gertsch & Mulaik, 1936 — United Sta ...

Ludwig Carl Christian Koch
Ludwig Carl Christian Koch (8 November 1825 – 1 November 1908) was a German entomologist and arachnologist. He was born in Regensburg, Germany, and died in Nuremberg, Germany. He studied in Nuremberg, initially law, but then turned to medicine and science. From 1850, he practiced as a physician in the Wöhrd district of Nuremberg. He is considered among the four most influential scientists on insects and spiders in the second half of the 19th century. He wrote numerous works on the arachinoids of Europe, Siberia, and Australia. His work earned him worldwide reputation as "Spider Koch". Sometimes confused with his father Carl Ludwig Koch (1778–1857), another famous arachnologist, his name is abbreviated L.Koch on species descriptions; his father's name is abbreviated C.L.Koch Pierre Bonnet. ''Bibliographia araneorum,'' (1945) Les frères Doularoude (Toulouse). Works ''Die Arachniden Australiens'' (1871-1883), his major work on Australian spiders, was completed by Eugen ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

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 ...

Oceania
Oceania (, , ) is a region, geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern Hemisphere, Eastern and Western Hemisphere, Western hemispheres, Oceania is estimated to have a land area of and a population of around 44.5 million as of 2021. When compared with (and sometimes described as being one of) the continents, the region of Oceania is the smallest in land area and the list of continents and continental subregions by population, second least populated after Antarctica. Its major population centres are Sydney, Melbourne, Brisbane, Perth, Auckland, Adelaide, Honolulu, and Christchurch. Oceania has a diverse mix of economies from the developed country, highly developed and globally competitive market economy, financial markets of Australia, French Polynesia, Hawaii, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much least developed countries, less developed ...

Cribellum
Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates. In certain groups of diatoms it refers to microscopically punctured regions of the frustule, or outer layer. In certain groups of spider species, so-called cribellate spiders, the cribellum is a silk spinning organ. Unlike the usual spinnerets of spiders, the cribellum consists of one or more plates covered in thousands of tiny spigots, tiny holes that hardly project from the surface, in contrast to the elongated spigots that project from spinnerets. These minute spigots produce extremely fine fibers, merely tens of nanometres thick, which are combed out by the spider's calamistrum, producing silk with a woolly texture. The fibers are so small in diameter that they are strongly subject to Van der Waals forces. In addition, the fibres have a surface that absorbs waxes from the epicuticle of insect prey on contact. This creates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneomorphae
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. Ima ...

Samoa
Samoa, officially the Independent State of Samoa; sm, Sāmoa, and until 1997 known as Western Samoa, is a Polynesian island country consisting of two main islands (Savai'i and Upolu); two smaller, inhabited islands (Manono Island, Manono and Apolima); and several smaller, uninhabited islands, including the Aleipata Islands (Nu'utele, Nu'ulua, Fanuatapu and Namua).

Spiders Of Oceania
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 Family (biology), families have been recorded by Taxonomy (biology), taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical Glossary of spider terms#pedice ...
