Monoblemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Carl Eduard Adolph Gerstaecker in 1941. [2]
As of September 2019 [update] it contains four species, found in Brazil, Panama, on Madagascar, in Colombia, and on the Virgin Islands: [1]
The recluse spiders, also known as brown spiders, fiddle-backs, violin spiders, and reapers, is a genus of spiders that was first described by R. T. Lowe in 1832. They are venomous spiders known for their bite, which sometimes produces a characteristic set of symptoms known as loxoscelism.
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.
Symphytognathidae is a family of spiders with 90 described species in eight genera. They occur in the tropics of Central and South America and the Australian region. Exceptions include Anapistula benoiti, Anapistula caecula, and Symphytognatha imbulunga, found in Africa, Anapistula ishikawai, found in Japan, and Anapistula jerai, found in Southeast Asia.
Castianeira is a genus of ant-like corinnid sac spiders first described by Eugen von Keyserling in 1879. They are found in Eurasia, Africa, and the Americas, but are absent from Australia. Twenty-six species are native to North America, and at least twice as many are native to Mexico and Central America.
Theridion is a genus of tangle-web spiders with a worldwide distribution. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.
Lygromma is a spider genus of Central and South America. There are species with eight, six and no eyes. The eyeless L. anops is endemic to Galapagos, while the not closely related blind L. gertschi is found only on Jamaica.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Anapis is a genus of araneomorph spiders in the family Anapidae, which consists of small orb weaving spiders all from the Neotropical realm. The genus includes close to thirty species and was first described by Eugène Simon in 1895.
Anapisona is a genus of araneomorph spiders in the family Anapidae, first described by Willis J. Gertsch in 1941.
Elaver is a genus of sac spiders first described by Octavius Pickard-Cambridge in 1898.
Creugas is a genus of corinnid sac spiders first described by Tamerlan Thorell in 1878.
Fallablemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978. As of September 2019 it contains two species, found on the Polynesian Islands and Sulawesi: F. castaneum and F. greenei.
Hexablemma is a monotypic genus of araneomorph spiders in the family Tetrablemmidae containing the single species, Hexablemma cataphractum. It was first described by Lucien Berland in 1920 from a female found in Kenya. It was separated from Tetrablemma in 1978 for this single species, because it doesn't belong there, but doesn't seem to belong anywhere else either.
Singaporemma is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Hentziectypus is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. Originally placed with Theridion, it was moved to Achaearanea in 1955, and to its own genus in 2008. These spiders most resemble members of Cryptachaea, but are distinguished by a median apophysis that is broadly attached to the tegulum. Spiders of Parasteatoda have a median apophysis attached to the embolus, while those of Achaearanea have a hooked paracymbium on the pedipalps of males.
Thymoites is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
Matta is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by C. R. Crosby in 1934.
