Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Embrik Strand was an entomologist and arachnologist who classified many insect and spider species, including the greenbottle blue tarantula.
Opisthoncana is a monotypic genus of jumping spiders containing the single species, Opisthoncana formidabilis. It was first described by Embrik Strand in 1913, and is only found on New Ireland. The name is a variation of the salticid genus Opisthoncus.
Microstigmatidae is a small family of spiders with about 38 described species in eleven genera. They are small ground-dwelling and free-living spiders that make little use of silk.
Lamponidae is a family of spiders first described by Eugène Simon in 1893. It contains about 200 described species in 23 genera, most of which are endemic to Australia, with the genus Centrocalia endemic to New Caledonia, and two Lampona species also occurring in New Zealand where they are commonly known as 'white-tailed spiders'. Lampona papua is endemic to New Guinea, where two otherwise Australian species also occur.
Agelena is a genus of agelenid spiders first described by Charles Athanase Walckenaer in 1805. Sometimes referred to as Eurasian grass spiders, they trap their prey by weaving entangling non-sticky funnel webs. They are limited to the Old World, occurring from Africa to Japan. Many species have been moved to other genera, particularly to Allagelena, Benoitia and Mistaria.
Badumna is a genus of intertidal spiders that was first described by Tamerlan Thorell in 1890. They are harmless spiders that can be found around human structures and buildings. The most well-known species is B. insignis, also known as the "black house spider" or "black window spider".
Delena is a genus of South Pacific huntsman spiders that was first described by Charles Athanase Walckenaer in 1837.
Cyrtophora, the tent-web spiders, is a genus of orb-weaver spiders first described by Eugène Simon in 1895. Although they are in the "orb weaver" family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimetres (0.39 in) long. Some members, including Cyrtophora cicatrosa, exhibit the ability to change colour rapidly.
Mistaria jumbo, synonym Agelena jumbo, is a species of spider in the family Agelenidae, which contains at least 1,350 species as of August 2021. It was first described by Embrik Strand in 1913 as Agelena jumbo. It is native to the Democratic Republic of the Congo and Rwanda.
Bassaniana, commonly called bark crab spiders, is a widespread genus of crab spiders that was first described by Embrik Strand in 1928.
Sidymella is a genus of spider in the family Thomisidae, found in South America, Australia and New Zealand. It was originally named Sidyma, but this was later found to have been used already for a genus of moths.
Holopelus is a genus of crab spiders that was first described by Eugène Louis Simon in 1886.
Mistaria is a genus of in the family Agelenidae first described by Pekka T. Lehtinen in 1967.
Lamponina is a genus of Australian white tailed spiders that was first described by Embrik Strand in 1913.
Acantharachne is a genus of African orb-weaver spiders first described by Albert Tullgren in 1910.
Aethrodiscus is a genus of African orb-weaver spiders containing the single species, Aethrodiscus transversalis. It was first described by Embrik Strand in 1913, and has only been found in Central Africa.
Anchonastus is a genus of African huntsman spiders that was first described by Eugène Louis Simon in 1898.
Oreonetides is a genus of dwarf spiders that was first described by Embrik Strand in 1901.
Mistaria kiwuensis is a species of spider in the family Agelenidae, which contains at least 1,350 species as of August 2021. It was first described by Strand in 1913 as the subspecies Agelena jumbo kiwuensis. Agelena jumbo was moved to the genus Mistaria in 2019, so that the subspecies became Mistaria jumbo kiwuensis. It was then elevated to the full species Mistaria kiwuensis later in the same year. It is native to the Democratic Republic of the Congo.
