Dorymetaecus
''Dorymetaecus'' is a monotypic genus of Australian araneomorph spiders in the family Phrurolithidae, containing the single species, ''Dorymetaecus spinnipes''. It was first described by William Joseph Rainbow in 1920, and has only been found on Lord Howe Island. Rainbow died in November 1919, shortly before publication of the work this species is described in. Description The holotype was found on Kentia palms, and only the female of this species is known. Its cephalothorax is long and wide. The opisthosoma The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma ( cephalothorax). It is a distinctive feature of the subphylum Chelicerata (arachnids, horseshoe crabs and others). Although it is similar in most respects ... is long and wide. Cephalothorax obovate, broad, well arched, yellow, with two dark-brown wavy lines behind the eyes, and with black lateral margins, close to which are smoky-brown patches.

Phrurolithidae
Phrurolithidae is a family of araneomorph spiders first described by Nathan Banks in 1892. First included in the Corinnidae as the subfamily Phrurolithinae, later phylogenetic studies justified a separate family. Genera , the World Spider Catalog The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature.

William Joseph Rainbow
William Joseph Rainbow (1856–1919) was an entomologist and arachnologist whose work includes the first catalogue of Australian spiders. Life Rainbow was born in 1856 in Yorkshire, England. His father was a Warrant Officer in the Royal Marines, so his education was in a number of port towns and in Edinburgh. He emigrated to New Zealand in 1873, where he wrote for John Ballance's ''Wanganui Herald''. Rainbow's early interest in natural history was assisted by Ballance, who prompted him to build a career in the field. In 1883 he moved to Sydney, Australia and married Arriette Dainty. He continued to contribute to newspapers and journals, including ''The Sydney Morning Herald'', ''Daily Telegraph'', and Evening News, then worked for the Government Printing Office until 1895; in this year he took up a position at the Australian Museum as an entomologist. Rainbow was a founder of the Naturalists' Society of New South Wales, serving as its president. He was a member of the Linnea ...

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 ...

Australia
Australia, officially the Commonwealth of Australia, is a sovereign ''Sovereign'' is a title which can be applied to the highest leader in various categories. The word is borrowed from Old French , which is ultimately derived from the Latin , meaning 'above'.

With an area of , Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical Forests of Australia, rainforests in the north-east, and List of mountains in Australia, mountain ranges in the south-east.

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 ...

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first reporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

Howea Forsteriana
''Howea forsteriana'', the Kentia palm, thatch palm or palm court palm, is a species of flowering plant in the palm family, Arecaceae, endemic to Lord Howe Island in Australia. It is also widely grown on Norfolk Island. It is a relatively slow-growing palm, eventually growing up to tall by wide. Its fronds can reach long. The palm received the name "forsteriana" after Johann Reinhold Forster and Georg Forster, father and son, who accompanied Captain Cook as naturalists on his second voyage to the Pacific in 1772–1775. The species is considered vulnerable by the World Conservation Union. It is cultivated on Lord Howe Island by collecting wild seeds and germinating them for export worldwide as an ornamental garden or house plant. The trade in the seeds and seedlings is tightly regulated. This plant has gained the Royal Horticultural Society's Award of Garden Merit. History ''Howea forsteriana'' gained great popularity as a houseplant in Europe and the United State ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider Anatomy
The anatomy of spiders includes many characteristics shared with other arachnids. These characteristics include bodies divided into two tagmata (sections or segments), eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed. Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male spiders have specialized pedipalps that are used to transfer sperm to the female during mating. Many species of spiders exhibit a great deal of sexual dimorphism. External anatomy Spiders, unlike insects, have only two main body parts ( tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) an ...

Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
