Sicariidae is a family of six-eyed venomous spiders known for their potentially necrotic bites. The family consists of three genera and about 160 species. Well known spiders in this family include the brown recluse spider and the six-eyed sand spider.
Ground spiders comprise Gnaphosidae, the seventh largest spider family with nearly 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include Gnaphosa, Drassodes, Micaria, Cesonia, Zelotes and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans.
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.
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is OonopsKeyserling, 1835.
Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks.
Cithaeronidae is a small family of araneomorph spiders first described by Simon in 1893 Female Cithaeron are about 5 to 7 millimetres long, males about 4 millimetres (0.16 in).
Gallieniellidae is a family of spiders first described by J. Millot in 1947. It was originally thought to be endemic to Madagascar until species were also found in southern Kenya, northeastern Argentina, and Australia. Drassodella was transferred from the family Gnaphosidae in 1990. They are suspected to be specialized in ant-preying.
Prodidominae is a spider subfamily, sometimes called long-spinneret ground spiders. It was formerly regarded as a separate family, Prodidomidae, which was reduced to a subfamily of the Gnaphosidae in 2018.
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.
Orsolobidae is a six-eyed spider family with about 180 described species in thirty genera. It was first described by J. A. L. Cooke in 1965, and was raised to family status from "Dysderidae" in 1985.
Barrowammo is a genus of North and West Australian termite hunters containing the single species, Barrowammo waldockae. It was first described by Norman I. Platnick in 2002, and has only been found in Australia. The name is a portmanteau of Barrow Island and Ammoxenidae.
Boolathana is a genus of spiders in the family Trochanteriidae found in western Australia. There are two species in the genus, Boolathana mainae and Boolathana spiralis. It is named after Boolathana Station, a pastoral lease near where the first specimen was found.
Boolathana spiralis is one of two species of western Australian spiders in the family Trochanteriidae. The name refers to the coiled tip of the middle apophysis, one of the defining characteristics of the species. It is mostly red to brown, the color fading from dark on the top front to gray in the sides and bottom.
Austrammo is a genus of Australian termite hunters first described by Norman I. Platnick in 2002.
Peeto is a monotypic genus of Australian araneomorph spiders in the family Gallieniellidae containing the single species, Peeto rodmani. It was first described by Norman I. Platnick in 2002, and has only been found in Australia.
Questo is a monotypic genus of Australian araneomorph spiders in the family Gallieniellidae containing the single species, Questo annuello, named after where it was found, Annuello, Victoria. It was first described by Norman I. Platnick in 2002, and has only been found in Australia.
Morebilus is a genus of spiders in the family Trochanteriidae found in southern and western Australia, first described by Norman I. Platnick in 2002. These are large spiders, with the carapace of males ranging from 10 to 16 millimeters and those of females ranging from 10 to 24 millimeters. They look similar to members of Rebilus, especially the spinneret and tarsal claw, but members of this genus have an inclined lip at the anterior edge of the sternum as well as a pair of enlarged sclerites on the coxal glands.
Oreo is a genus of Australian araneomorph spiders in the family Gallieniellidae, and was first described by Norman I. Platnick in 2002. The name derives from the Oreo cookie. The type species has a black and white abdomen, although such coloration is common among gallieniellids.
Neato is a genus of Australian araneomorph spiders in the family Gallieniellidae, and was first described by Norman I. Platnick in 2002.
