Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is OonopsKeyserling, 1835.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water.
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.
Theridiosomatidae, commonly known as Ray Spiders, are a family of araneomorph spiders first described by Eugène Simon in 1881. The family includes 137 species divided between 20 genera. They are most recognizable for their construction of cone-shaped webs.
Ochyroceratidae is a six-eyed spider family, with 165 described species in ten genera. They are common inhabitants of caves and the tropical forest litter of South Africa, the Caribbean, Asia and South America. Considered an ecological counterpart of the Linyphiidae of the northern temperate zone, species are especially diverse in the Indo-Pacific region.
Telemidae, also known as long-legged cave spiders, is a family of small haplogyne spiders. Most are cave dwelling spiders with six eyes, though some do not have any eyes at all. There are about 104 described species in sixteen genera.
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.
Nesticella is a genus of spiders of the family Nesticidae. Most of its species are found in Asia—from Russia to Japan, down to Indonesia and several other islands, including New Guinea—though some species from Africa and South-America are also known. It includes a blind spider, Nesticella marapu.
Aituaria is a genus of spiders in the family Nesticidae. It was first described in 1998 by Esyunin & Efimik. As of 2016, it contains two species, Aituaria nataliae and Aituaria pontica, the latter of which was transferred from Nesticus first to Carpathonesticus, then to Aituaria.
Carpathonesticus is a genus of spiders in the family Nesticidae. It was first described in 1980 by Lehtinen & Saaristo. As of December 2019, it contains 21 species.
Kryptonesticus is a genus of European scaffold web spiders first described by Pavlek & Ribera in 2017, based around the newly described type species Kryptonesticus deelemanae and seven species transferred from genus Nesticus. In 2018, an additional species, K. georgescuae, was described from two female specimens from Romania.
Speleoticus is a spider genus in the family Nesticidae. Its species are found in Japan and China.
Aituaria pontica is an araneomorph spider of the family Nesticidae. It occurs in the Krasnodar region of Russia and in Georgia.
Carpathonesticus borutzkyi is a species of araneomorph spider of the family Nesticidae. It occurs in Russia, Georgia, Turkey and Ukraine and is found in caves.
Carpathonesticus simoni is an araneomorph spider species of the family Nesticidae. It occurs in Romania, where it can be found in caves. It was transferred from the genus Nesticus to Carpathonesticus in 1980 by Lehtinen and Saaristo.
Carpathonesticus spelaeus is an araneomorph spider species of the family Nesticidae. It occurs in Romania, where it can be found in caves and outdoors under calcareous blocks. It was transferred from the genus Nesticus to Carpathonesticus in 1980 by Lehtinen and Saaristo.
Yunohamella is a genus of comb-footed spiders that was first described by H. Yoshida in 2007.
