Migidae, also known as tree trapdoor spiders, is a family of spiders with about 100 species in eleven genera. They are small to large spiders with little to no hair and build burrows with a trapdoor. Some species live in tree fern stems. They have a Gondwanan distribution, found almost exclusively on the Southern Hemisphere, occurring in South America, Africa, Madagascar, Australia, New Zealand and New Caledonia.
Ochyroceratidae is a six-eyed spider family, with 165 described species in ten genera. They are common inhabitants of caves and the tropical forest litter of South Africa, the Caribbean, Asia and South America. Considered an ecological counterpart of the Linyphiidae of the northern temperate zone, species are especially diverse in the Indo-Pacific region.
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).
Trochanteriidae is a family of spiders first described by Ferdinand Karsch in 1879 containing about 52 species in 6 genera. Most are endemic to Australia though Doliomalus and Trochanteria are from South America and Plator is from Asia. Platyoides species exist in southern and eastern Africa, Madagascar, and the Canary Islands with one species, P. walteri, introduced to Australia.
Palpimanidae, also known as palp-footed spiders, is a family of araneomorph spiders first described by Tamerlan Thorell in 1890. They are widely distributed throughout the tropical and subtropical regions of the world, the Mediterranean and one in Uzbekistan, but not Australia. They are not common and there is a high degree of endemism.
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from 2 to 8 millimetres long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and thick. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand.
The Gnaphosoidea or gnaphosoids are a superfamily of araneomorph spiders with seven families. A 2014 study did not find the group to be monophyletic.
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 Trachycosmidae 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 colour fading from dark on the top front to gray in the sides and bottom.
Austrammo is a genus of Australian Ground spiders first described by Norman I. Platnick in 2002.
Galianoella is a monotypic genus of South American araneomorph spiders in the family Gallieniellidae containing the single species, Galianoella leucostigma. It was first described by Pablo A. Goloboff in 2000, breaking it off from Azilia. It has only been found in Argentina. The genus is named in honour of María Elena Galiano.
Gallieniella is a genus of East African araneomorph spiders in the family Gallieniellidae, and was first described by J. Millot in 1947. Originally placed with the sac spiders, it was moved to the Gallieniellidae in 1967.
Legendrena is a genus of East African araneomorph spiders in the family Gallieniellidae, and was first described by Norman I. Platnick in 1984.
Peeto is a monotypic genus of Australian araneomorph spiders in the family Trachycosmidae 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 Trachycosmidae 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 Trachycosmidae 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 Trachycosmidae, 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 Trachycosmidae, and was first described by Norman I. Platnick in 2002.
