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.
Phyxelididae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967 as a subfamily of Amaurobiidae, and later elevated to family status as a sister group of Titanoecidae.
Cyatholipidae is a family of spiders first described by Eugène Simon in 1894. Most live in moist montane forest, though several species, including Scharffia rossi, live in dry savannah regions. They occur in Africa, including Madagascar, New Zealand and Australia, and one species in Jamaica. Most members of this family hang beneath sheet webs. Fossil species occur in the Eocene aged Bitterfield and Baltic Ambers, suggesting a wider geographic distribution in the past.
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 fat. 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 Entelegynae or entelegynes are a subgroup of araneomorph spiders, the largest of the two main groups into which the araneomorphs were traditionally divided. Females have a genital plate (epigynum) and a "flow through" fertilization system; males have complex palpal bulbs. Molecular phylogenetic studies have supported the monophyly of Entelegynae.
Udubidae is a family of araneomorph spiders, most of whose members were formerly placed in the family Zorocratidae, which is no longer accepted.
Viridasiidae is a family of araneomorph spiders split from the family Ctenidae in 2015.
Zorodictyna is a genus of spiders in the family Udubidae native to Madagascar. It has been described as an intermediate genus between Zoropsidae and Dictynidae, though it is now placed in Udubidae. This genus was originally placed in the family Zoropsidae, but it has been reassigned several times since. In 1967, Lehtinen moved it to Miturgidae. In 1999, it was moved back to Zoropsidae, and in 2015, it was moved to Udubidae.
Viridasius is a monotypic genus of East African araneomorph spiders in the family Viridasiidae, containing the single species, Viridasius fasciatus. It was first described by Eugène Simon in 1889, and has only been found in Madagascar.
Ambohima is a genus of Malagasy araneomorph spiders in the family Phyxelididae, and was first described by C. E. Griswold in 1990.
Kulalania is a monotypic genus of Kenyan araneomorph spiders in the family Phyxelididae containing the single species, Kulalania antiqua. It was first described by C. E. Griswold in 1990, and is only found in Kenya.
Namaquarachne is a genus of South African araneomorph spiders in the family Phyxelididae, and was first described by C. E. Griswold in 1990.
Phyxelida is a genus of araneomorph spiders in the family Phyxelididae, and was first described by Eugène Louis Simon in 1894.
Pongolania is a genus of South African araneomorph spiders in the family Phyxelididae, and was first described by C. E. Griswold in 1990. As of June 2019 it contains only two species, found only in South Africa: P. chrysionaria and P. pongola.
Rahavavy is a genus of Malagasy araneomorph spiders in the family Phyxelididae, and was first described by C. E. Griswold, H. M. Wood & A. D. Carmichael in 2012. As of June 2019 it contains only three species, found only on Madagascar: R. fanivelona, R. ida, and R. malagasyana.
Vulsor is a genus of araneomorph spiders in the family Viridasiidae, first described by Eugène Simon in 1889. Originally placed with the wandering spiders, it was moved to the Viridasiidae in 2015.
Xevioso is a genus of African araneomorph spiders in the family Phyxelididae, and was first described by Pekka T. Lehtinen in 1967.
Vidole is a genus of African araneomorph spiders in the family Phyxelididae, and was first described by Pekka T. Lehtinen in 1967.
