Nanocambridgea
''Nanocambridgea'' is a monotypic genus of intertidal spiders containing the single species, ''Nanocambridgea gracilipes''. It was first described by Raymond Robert Forster & C. L. Wilton in 1973, and is found on New Zealand. Originally placed with the Stiphidiidae, it was moved to the Desidae after a 2017 genetic study. A male described as ''N. grandis'' in 2000 was synonymized with '' Cambridgea reinga'' in 2011.

Cambridgea
''Cambridgea'' (common name New Zealand sheetweb spider, bush spider) is a spider genus in the family Desidae and some of the first endemic spiders described from New Zealand. They are known for constructing large horizontal sheet webs measuring up to a square metre in larger species. ''Cambridgea'' were originally assigned to the Agelenidae by Dalmas in 1917 but were reassigned to the Stiphidiidae in 1973. Most recently, both ''Cambridgea'' and sister genus ''Nanocambridgea'' were reassigned to the Desidae, subfamily Porteriinae on the basis of molecular evidence. Description ''Cambridgea'' are medium to large arboreal spiders, with body lengths ranging from approximately 6-10mm in the case of '' Cambridgea reinga'' to about 20mm in the case of '' Cambridgea foliata''. They have long legs and porrect chelicerae which are significantly longer in adult males compared to adult females. Male pedipalps are characterised by a cymbium that extends well beyond the bulb and species ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desidae
Desidae is a family of spiders, some of which are known as intertidal spiders. The family is named for the genus '' Desis'', members of which live in a very unusual location — between the tides. The family has been reevaluated in recent years and now includes inland genera and species as well, such as ''Badumna'' and ''Phryganoporus''. In 2017, the family Amphinectidae was merged into Desidae. The family Toxopidae has been separated off. Those intertidal spiders that are truly marine commonly live in barnacle shells, which they seal up with silk; this allows them to maintain an air bubble during high tide. They emerge at night to feed on various small arthropods that live in the intertidal zone. Distribution As now circumscribed, the family Desidae is mainly found in South America and Australasia, with some species reaching north to Malaysia. ''Metaltella simoni'' has been introduced in a large part of the Southern United States (records exist from California, Louisiana, Missis ...

Raymond Robert Forster
Raymond Robert Forster (19 June 1922 – 1 July 2000) was a New Zealand arachnologist and museum director. He was a Fellow of the Entomological Society of New Zealand. Biography Forster was born in Hastings, New Zealand in 1922, and was educated at Victoria University College, gaining BSc, MSc(Hons) and DSc degrees. Forster was an entomologist at the National Museum in Wellington from 1940 to 1947, with an interruption for military service during World War II. Between 1942 and 1945 he served first in the army and then as a naval radar mechanic.Ray Forster obituary . International Society of Arachnology. Retrieved 14 February 2013.

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 trichopod ...

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 cl ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Stiphidiidae
Stiphidiidae, also called sheetweb spiders, is a family of araneomorph spiders first described in 1917. Most species are medium size ('' Stiphidion facetum'' is about long) and speckled brown with long legs. All members of this family occur in New Zealand and Australia except for ''Asmea''. They build a horizontal sheet-like web under rocks, hence the name "sheetweb spiders". The largest of New Zealand's species is '' Cambridgea foliata'', with a body length up to and a span of up to . Hikers and trampers often find their sheet-like webs that can be up to across, but the spider itself is nocturnal, spending the day time inside its web tunnel. It can also be found in gardens and males may enter human homes. Their large size, including mouth parts up to long, may be intimidating, but it is considered harmless to humans and bites are extremely rare. Genera , the World Spider Catalog accepts the following genera: *'' Aorangia'' Forster & Wilton, 1973 — New Zealand *''Asmea ...

Spiders Of New Zealand
New Zealand has 1157 described spider species, with an estimated total fauna of 2000 species. Over 97 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions. The New Zealand spider with the largest leg span is the Nelson cave spider (''Spelungula cavernicola''), with a leg span of up to and a body length. The Australian white-tailed spider, first recorded in New Zealand in 1886, has been falsely attributed as the cause of many necrotising spider bites. The flat huntsman spider ('' Delena cancerides''), also from Australia, and called the Avondale spider in New Zealand, was accidentally introduced in the early 1920s, possibly in shipments of hardwood logs used for railway sleepers.Rowell and Avilés (1995).
