Microbathyphantes is a genus of dwarf spiders that was first described by P. J. van Helsdingen in 1985. [3]
As of May 2019 [update] it contains five species: [1]
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Linyphiidae is a family of very small spiders comprising 4667 described species in 618 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly known; new genera and species are still being discovered throughout the world. The newest such genus is Yuelushannus from China, formally described in May 2020. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera. Most spiders in this family build trapdoor burrows. For example, the 20 millimetres (0.79 in) long Sipalolasma builds its burrow in rotted wood, with a hinged trapdoor at each end. The 10 millimetres (0.39 in) long Idioctis builds its burrow approximately 5 centimetres (2.0 in) deep, just below the high tide level, sealing the opening with a thin trapdoor.
Neriene is a genus of sheet weavers that was first described by John Blackwall in 1833.
Sason is a genus of bark-dwelling brushed trapdoor spiders first described by Eugène Simon in 1887. It is distributed from the Seychelles through India to northern Australia. The closest related genus seems to be the monotypic Paracenobiopelma.
Microlinyphia is a genus of dwarf spiders that was first described by U. Gerhardt in 1928.
Andasta is a genus of ray spiders that was first described by Eugène Louis Simon in 1895.
Oedignatha is a genus of Asian spiders first described by Tamerlan Thorell in 1881 as a genus of corrinid sac spiders, and moved to Liocranidae in 2014.
Helsdingenia ceylonica, is a species of spider of the genus Helsdingenia. It is found only in Nepal and Sri Lanka.
Helsdingenia is a genus of dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2003. The name is a reference to Dr. P. J van Helsdingen.
Labullinyphia is a monotypic genus of Asian dwarf spiders containing the single species, Labullinyphia tersa. It was first described by P. J. van Helsdingen in 1985, and has only been found in Sri Lanka.
Neriene katyae is a species of spider of the genus Neriene. It is endemic to Sri Lanka.
Nesioneta benoiti, is a species of spider of the genus Nesioneta. It is endemic to Sri Lanka.
Nesioneta is a genus of dwarf spiders that was first described by J. A. Beatty, J. W. Berry & Alfred Frank Millidge in 1991.
Frontinellina is a genus of dwarf spiders that was first described by P. J. van Helsdingen in 1969. As of May 2019 it contains only three species, found in Kazakhstan, Portugal, Russia, South Africa, and Turkey: F. dearmata, F. frutetorum, and F. locketi.
Mitrager is a monotypic genus of Southeast Asian dwarf spiders containing the single species, Mitrager noordami. It was first described by P. J. van Helsdingen in 1985, and has only been found in Indonesia.
Oreonetides is a genus of dwarf spiders that was first described by Embrik Strand in 1901.
Ostearius is a genus of dwarf spiders that was first described by J. E. Hull in 1911. As of May 2019 it contains only two species, both found in Spain, Turkey, Egypt, China, South Africa, and New Zealand: O. melanopygius and O. muticus.
Turinyphia is a genus of sheet weavers that was first described by P. J. van Helsdingen in 1982.
Michael I. Saaristo was a Finnish arachnologist, with a particular interest in the spiders of the Seychelles. The World Spider Catalog lists 61 genus names or synonyms and 109 species names or synonyms of which he is the sole or co-author.
