Yupanquia is a genus of South American tangled nest spiders containing the single species, Yupanquia schiapelliae. It was first described by Pekka T. Lehtinen in 1967, [2] and has only been found in Argentina. [1]
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.
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.
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.
Pekka T. Lehtinen is a Finnish arachnologist and taxonomist. He is known for his works in systematics and for the many expeditions in which he has participated.
Devendra is a genus of Asian false wolf spiders first described by Pekka T. Lehtinen in 1967.
Arctobius is a genus of tangled nest spiders containing the single species, Arctobius agelenoides. It was first described by Pekka T. Lehtinen in 1967, with a holarctic distribution.
Yacolla is a genus of South American tangled nest spiders containing the single species, Yacolla pikelinae. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Brazil.
Marplesia is a genus of South Pacific sheetweb spiders first described by Pekka T. Lehtinen in 1967. As of April 2019 it contains only two species, both found in New Zealand.
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.
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.
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.
Tahuantina is a monotypic genus of South American cribellate araneomorph spiders in the family Dictynidae containing the single species, Tahuantina zapfeae. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Chile.
Brigittea is a genus of araneomorph spiders in the family Dictynidae, first described by Pekka T. Lehtinen in 1967.
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.
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.
