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.
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) is 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.
Dolichognatha is a genus of tropical and subtropical long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1869. Originally placed with the Archaeidae, it was transferred to the Araneidae in 1967, and to the Tetragnathidae in 1981.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Acartauchenius is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1884.
Robertus is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1879. It is considered a senior synonym of Garritus.
Schenkeliella is a monotypic genus of Sri Lankan long-jawed orb-weavers containing the single species, Schenkeliella spinosa. The species was first described by Octavius Pickard-Cambridge in 1871 under the name Oeta spinosa, but it was renamed to "Schenkeliella" by Embrik Strand in 1934 because the name was already in use for a genus of ermine moths. Originally placed with the Nesticidae, it transferred to the Tetragnathidae in 1980.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
Cyrtognatha is a genus of long-jawed orb-weavers that was first described by Eugen von Keyserling in 1881. It is a senior synonym of Agriognatha.
Leviellus, synonym Stroemiellus, is a genus of orb-weaver spiders first described by J. Wunderlich in 2004.
Nomisia is a genus of ground spiders that was first described by R. de Dalmas in 1921.
Pulchellodromus is a genus of running crab spiders that was first separated from Philodromus by J. Wunderlich in 2012.
Centromerus is a genus of dwarf spiders that was first described by David B. Hirst in 1886.
Erigonoplus is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1884.
Micrargus is a genus of dwarf spiders that was first described by Friedrich Dahl in 1886.

Bassaniodes is a genus of crab spiders that was first described by Reginald Innes Pocock in 1903.
Wamba is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1896. As of September 2019 it contains three species, found in the Americas, including the Caribbean: W. congener, W. crispulus, and W. panamensis.
Allende is a genus of South American long-jawed orb-weavers that was first described by F. Álvarez-Padilla in 2007.
