Uloboridae is a family of nonvenomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
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 (Eresidae) are a small group of almost totally Old World spiders. 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.
Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2019, the family Amaurobiidae includes about 275 species in 49 genera.
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
Tetrablemmidae, sometimes called armored spiders, is a family of tropical araneomorph spiders first described by Octavius Pickard-Cambridge in 1873. It contains 126 described species in 29 genera from southeast Asia, with a few that occur in Africa and Central and South America. Pacullidae was incorporated into this family in 1981, but was later restored as a separate family in a 2016 phylogenetic study.
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.
Benoitia is a genus of funnel weavers first described by Pekka T. Lehtinen in 1967.
Kidugua is a genus of Central African funnel weavers containing the single species, Kidugua spiralis. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Africa.
Olorunia is a genus of Central African funnel weavers containing the single species, Olorunia punctata. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Africa.
Mashimo is a monotypic genus of East African cribellate araneomorph spiders in the Dictynidae family containing the single species, Mashimo leleupi. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Zambia.
Gandanameno is a genus of African velvet spiders that was first described by Pekka T. Lehtinen in 1967.
Phyxelida is a genus of spiders in the Phyxelididae family. It was first described in 1894 by Simon. As of 2017, it contains 17 species.
Obatala is a genus of African tangled nest spiders containing the single species, Obatala armata. It was first described by Pekka T. Lehtinen in 1967, and has only been found in South Africa.
Shango is a monotypic genus of African cribellate araneomorph spiders in the Dictynidae family containing the single species, Shango capicola. It was first described by Pekka T. Lehtinen in 1967, and has only been found in South Africa.
Megadictynidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. They are endemic to New Zealand.
Xevioso is a genus of African araneomorph spiders in the Phyxelididae family, first described by Pekka T. Lehtinen in 1967.
Vidole is a genus of African araneomorph spiders in the Phyxelididae family, first described by Pekka T. Lehtinen in 1967.
Malaika is a genus of African araneomorph spiders in the Phyxelididae family, first described by Pekka T. Lehtinen in 1967. As of April 2019 it contains only two species.
