Phyxelididae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967 as a subfamily of Amaurobiidae, [1] and later elevated to family status as a sister group of Titanoecidae. [2]
As of April 2019 [update] , the World Spider Catalog accepts the following genera: [3]
The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus Agelenopsis. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider may be medically significant, and some evidence suggests it might cause necrotic lesions. However, the matter remains subject to debate. The most widely accepted common name for members of the family is funnel weaver.
Crevice weaver spiders (Filistatidae) comprise cribellate spiders with features that have been regarded as "primitive" for araneomorph spiders. They are weavers of funnel or tube webs. The family contains 18 genera and more than 120 described species worldwide.
Titanoecidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. It is fairly widespread in the New World and Eurasia with five genera and more than 50 species worldwide. These are mostly dark-colored builders of "woolly" (cribellate) silk webs. Several species are found at relatively high altitudes in mountain ranges and may be very common in such habitats.
Velvet spiders are a small group of spiders almost entirely limited to the Old World, with exception of a few species known from Brazil. The characteristics of this family of spiders are that they are entelegyne, eight-eyed araneomorph spiders that build unkempt webs. They are cribellate. Some species are nearly eusocial, lacking only a specialized caste system and a queen. They cooperate in brood rearing, unlike most other spiders except for some African agelenid spiders in the genus Agelena and a few others.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
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.
Penestomus is a genus of African araneomorph spiders in the family Penestomidae, and was first described by Eugène Louis Simon in 1902. The genus was formerly included in the family Eresidae, but was elevated to its own family in 2010. It is now considered closer to Zodariidae.
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.
Drymusidae is a family of araneomorph spiders first described by Eugène Simon in 1893, and elevated to family status by Pekka T. Lehtinen in 1986.
Ambohima is a genus of Malagasy araneomorph spiders in the family Phyxelididae, and was first described by C. E. Griswold in 1990.
Manampoka is a monotypic genus of Malagasy araneomorph spiders in the family Phyxelididae containing the single species, Manampoka atsimo. It was first described by C. E. Griswold, H. M. Wood & A. D. Carmichael in 2012, and is only found on Madagascar.
Matundua is a monotypic genus of South African araneomorph spiders in the family Phyxelididae containing the single species, Matundua silvatica. It was first described by Pekka T. Lehtinen in 1967, and is only found in South Africa.
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.
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.
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.
Malaika is a genus of South African araneomorph spiders in the family Phyxelididae, and was first described by Pekka T. Lehtinen in 1967. As of June 2019 it contains only two species, found only in South Africa: M. delicatula and M. longipes.
