The Thomisidae are a family of spiders, including about 175 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders.
Philodromidae, also known as philodromid crab spiders and running crab spiders, is a family of araneomorph spiders first described by Tord Tamerlan Teodor Thorell in 1870. It contains over 600 species in thirty genera. Most are dull colored- brown, gray, yellowish or mottled with a leaf-like cardiac mark on the anterior dorsal abdomen, and seldom reach above 10 millimetres (0.39 in) long. None of the species build webs, but they do use silk for draglines and egg sacs.
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 25 described species in eight 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 it is commonly known as the "White Tail" spider. 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.
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. They are darkly colored, usually with a lighter colored pattern on the abdomen. 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.
Ctenolophus is a genus of African armored trapdoor spiders that was first described by William Frederick Purcell in 1904. Originally placed with the Ctenizidae, it was moved to the Idiopidae in 1985.
Bassaniana, commonly called bark crab spiders, is a widespread genus of crab spiders that was first described by Embrik Strand in 1928.
Obrimona is a monotypic genus of Asian dwarf spiders containing the single species, Obrimona tennenti. It was first described by Embrik Strand in 1934, and has only been found in Sri Lanka.
Holopelus is a genus of crab spiders that was first described by Eugène Louis Simon in 1886.
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.
Caripetella is a monotypic genus of East African nursery web spiders containing the single species, Caripetella madagascariensis. It was first described by Embrik Strand in 1928, and is only found on Comoros and on Madagascar.
Oreonetides is a genus of dwarf spiders that was first described by Embrik Strand in 1901.
