Spitting spiders (Scytodidae) is a family of araneomorph spiders first described by John Blackwall in 1864. It contains over 250 species in five genera, of which Scytodes is the best-known.
Linyphiidae is a family of very small spiders comprising 4667 described species in 618 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly known; new genera and species are still being discovered throughout the world. The newest such genus is Yuelushannus from China, formally described in May 2020. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found in all tropical and subtropical regions of South America, Africa, Madagascar, Australia-New Guinea, New Zealand, Arabia and the Indian subcontinent. Most species are daytime hunters and live together with ants, mimicking their behavior and sometimes even their chemical traits. Although little is known about most zodariids, members of the genus Zodarion apparently feed only on ants; a number of other genera in the family are apparently also ant specialists.
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.
The ray spiders (Theridiosomatidae) are a family of spiders first described by Eugène Simon in 1881. They are most recognizable for their construction of cone-shaped webs.
Antrodiaetidae, also known as folding trapdoor spiders, is a small spider family related to atypical tarantulas. They are found almost exclusively in the western and midwestern United States, from California to Washington and east to the Appalachian mountains. Exceptions include Antrodiaetus roretzi and Antrodiaetus yesoensis, which are endemic to Japan and are considered relict species. It is likely that two separate vicariance events led to the evolution of these two species.
Mysmenidae is a spider family with about 135 described species in thirteen genera. The family is one of the least well known of the orb-weaving spiders because of their small size and cryptic behaviour. These spiders are found in humid habitats such as among leaf litter and in caves.
Penestomus is a genus of African araneomorph spiders in the family Penestomidae, and was first described by Eugène Louis Simon in 1902. The genus was formerly included in the family Eresidae, but was elevated to its own family in 2010. It is now considered closer to Zodariidae.

The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database.
Arandisa is a monotypic genus of Namibian huntsman spiders containing the single species, Arandisa deserticola. It was first described by R. F. Lawrence in 1938, and is found in Namibia.
Echemoides is a genus of South American ground spiders that was first described by Cândido Firmino de Mello-Leitão in 1938. Originally placed with the ant spiders, it was moved to the ground spiders in 1993.
Centrophantes is a genus of European dwarf spiders that was first described by F. Miller & A. Polenec in 1975. As of May 2019 it contains only two species: C. crosbyi and C. roeweri.
Machadocara is a genus of African dwarf spiders that was first described by F. Miller in 1970. As of May 2019 it contains only two species, both found in Middle Africa and Zambia: M. dubia and M. gongylioides.
Moreiraxena is a monotypic genus of Central African dwarf spiders containing the single species, Moreiraxena chicapensis. It was first described by F. Miller in 1970, and has only been found in Angola.
Pseudomicrocentria is a genus of sheet weavers that was first described by F. Miller in 1970. As of May 2019 it contains only two species, both found in Malaysia and South Africa: P. minutissima and P. simplex.
Psilocymbium is a genus of South American sheet weavers that was first described by Alfred Frank Millidge in 1991.
Sisicottus is a genus of sheet weavers that was first described by S. C. Bishop & C. R. Crosby in 1938. They can be found in moss and litter of conifer forests.
Michael I. Saaristo was a Finnish arachnologist, with a particular interest in the spiders of the Seychelles. The World Spider Catalog lists 61 genus names or synonyms and 109 species names or synonyms of which he is the sole or co-author.
Ikuma is a genus of Namibian palp-footed spiders that was first described by R. F. Lawrence in 1938. As of June 2019 it contains only two species, found only in Namibia: I. spiculosa and I. squamata.
