Uloboridae is a family of non-venomous 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 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.
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.
Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates.
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.
Mexitlia is a genus of North American cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only three species: M. altima, M. grandis, and M. trivittata.
Namandia is a monotypic genus of Australian intertidal spiders containing the single species, Namandia periscelis. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Australia.
Arangina is a genus of South Pacific cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only two species, both found in New Zealand: A. cornigera and A. pluva.
Banaidja is a monotypic genus of South Pacific cribellate araneomorph spiders in the family Dictynidae containing the single species, Banaidja bifasciata. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Samoa. The type species was transferred from Dictyna in 1929, retaining the original species name.
Hackmania is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only two species: H. prominula and H. saphes.
Iviella is a genus of North American cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only three species: I. newfoundlandensis, I. ohioensis, and I. reclusa.
Marilynia is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only two species: M. bicolor and M. bicolor.
Mashimo is a monotypic genus of East African cribellate araneomorph spiders in the family Dictynidae containing the single species, Mashimo leleupi. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Zambia.
Sudesna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967.
Brigittea is a genus of araneomorph spiders in the family Dictynidae, first described by Pekka T. Lehtinen in 1967.
Shango capicola is a species of African cribellate araneomorph spiders in the family Dictynidae. It is the only species in the monotypic genus Shango. The genus was first described by Pekka T. Lehtinen in 1967, and has only been found in South Africa.
Intihuatana antarctica is a species of South American spider in the dwarf sheet spider family, Hahniidae. It is the only species in the monotypic genus Intihuatana. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Argentina.
Megadictynidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. They are endemic to New Zealand.
Tangaroa is a genus of South Pacific cribellate orb-weavers first described by Pekka T. Lehtinen in 1967.
