Zhinu is a genus of spiders in the family Tetragnathidae. [1]
As of September 2018 [update] , the World Spider Catalog accepted the following extant species: [1]
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water.
Spider taxonomy is that part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida with more than 48,500 described species. However, there are likely many species that have escaped the human eye to this day, and many specimens stored in collections waiting to be described and classified. It is estimated that only one third to one half of the total number of existing species have been described.
Pimoidae is a small family of araneomorph spiders first described by J. Wunderlich in 1986. As re-circumscribed in 2021, it is monophyletic, and contained 85 species in two genera. It is closely related to the Linyphiidae, and is sometimes treated as synonymous with that family.
Leucauge is a spider genus of long-jawed orb weavers, with over 160 species and fully pantropical distribution.
Chorizopes is a genus of orb-weaver spiders first described by O. Pickard-Cambridge in 1871. Though it belongs to the orb weaver family, these spiders move through leaf litter preying on other spiders rather than spinning webs. The original name was "Chorizoopes", but the emendationChorizopes by Tamerlan Thorell is now protected by usage.
Dolichognatha is a genus of tropical and subtropical long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1869. Originally placed with the Archaeidae, it was transferred to the Araneidae in 1967, and to the Tetragnathidae in 1981.
Taraire is a small genus of Polynesian long-jawed orb-weavers. The genus was first described by A. Álvarez-Padilla, R. J. Kallal and Gustavo Hormiga in 2020, and it has only been found in New Zealand. They build vertical orb webs near forest floors, and can be found resting in the center. The genus name is a reference to Beilschmiedia tarairi, the native New Zealand tree that they are commonly found in.
Phonognatha is a genus of South Pacific orb-weaver spiders first described by Eugène Simon in 1895. It was originally placed with the long-jawed orb weavers, and was moved to Araneidae in 2008.
Pinkfloydia is a genus of small Australian long-jawed orb-weavers, reaching a maximum lengths of about 4.5 millimetres (0.18 in). It was first described by D. Dimitrov & G. Hormiga in 2011, and contains two species, found in New South Wales and Western Australia: P. harveyi and P. rixi. They have a unique rounded, cone-shaped head structure with one pair of large eyes and three pairs of smaller eyes. The genus is named after British rock band Pink Floyd.
Orsonwelles is a genus of American dwarf spiders that was first described by G. Hormiga in 2002. They are all native to the Hawaiian Islands, each species occurring on a single island, often at high elevations. One species has not been collected since the 1890s, and is believed to be extinct. The name honors the actor and film-maker Orson Welles. Many of the species names commemorate elements from Welles' films, radio productions, or roles.
Dolichognatha junlitjri is a species of orb-weaver spiders found in the Philippines. The species was discovered in Molawin Creek at Mount Makiling, and was described, illustrated and named by Aimee Lynn Barrion-Dupo and Alberto T. Barrion who published their discovery in 2014. They considered that the genus Prolochus, treated a synonym of Dolichognatha by sources such as the World Spider Catalog as of January 2021, should be revived. It would include Dolichognatha longiceps as Prolochus longiceps, and Prolochus junlitjri. However, a molecular phylogenetic study in 2018 did not support this, and placed the species in Dolichognatha, the placement accepted by the World Spider Catalog.
Guizygiella is a genus of Asian orb-weaver spiders that was first described by M. S. Zhu, J. P. Kim and D. X. Song in 1997. It was transferred from the family Tetragnathidae to Araneidae by Kallal & Hormiga in 2022.
Nanometa is a genus of long-jawed orb-weavers containing the fifteen species. It was erected by Eugène Louis Simon based on the type specimen of Nanometa gentilis found in 1908. It is included in a clade of its own defined by nine morphological synapomorphies, along with the genus Orsinome.
Orsinome is a genus of long-jawed orb-weavers that was first described by Tamerlan Thorell in 1890. It is included in the Nanometa clade, defined by nine morphological synapomorphies, along with Eryciniolia and Nanometa.
Artifex melanopyga, synonym Phonognatha melanopyga, referred to as a leaf curling spider, is a common Australian spider found in moist coastal areas of New South Wales and Queensland. A small member of the family Araneidae, the orb-weavers, it was previously placed in Tetragnathidae.
Artifex is a small genus of orb-weaver spiders native to tropical regions of mainland Australia and to New Caledonia. The genus was erected by R. J. Kallal and Gustavo Hormiga in 2018 to contain two species moved from different genera that have several synapomorphies, including an abdomen that extends past the spinnerets, widely separated spermathecae, and dorsal markings similar to those of Zygiellinae. The name is a combination of the Latin "ars", meaning "art", and "-fex", meaning "maker" in reference to the shelters they build out of leaves.
Harlanethis is a small genus of Australian long-jawed orb-weavers. It was first described by A. Álvarez-Padilla, R. J. Kallal and Gustavo Hormiga in 2020, and it has only been found in Australia. As of April 2022 it contains only two species: H. lipscombae and H. weintrauborum.
Iamarra is a monotypic genus of Australian long-jawed orb-weavers containing the single species, Iamarra multitheca. It was first described by A. Álvarez-Padilla, R. J. Kallal and Gustavo Hormiga in 2020, and it has only been found in Australia.
Tawhai is a monotypic genus of Polynesian long-jawed orb-weavers containing the single species Tawhai arborea. The genus was first described by A. Álvarez-Padilla, R. J. Kallal and Gustavo Hormiga in 2020, and it has only been found in New Zealand. The type species, Tawhai arborea, was originally described under the name "Tetragnatha arborea".
