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.
Anatea is an ant-mimicking genus of South Pacific comb-footed spiders that was first described by Lucien Berland in 1927. As of May 2020 it contains three species, found in Australia and on New Caledonia:
Brignoliella is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Gunasekara is a monotypic genus of Sri Lankan araneomorph spiders in the family Tetrablemmidae containing the single species, Gunasekara ramboda. It was first described by Pekka T. Lehtinen in 1981, and is found in Sri Lanka.
Afroblemma is a monotypic genus of African araneomorph spiders in the family Tetrablemmidae containing the single species, Afroblemma thorelli. It was first described by Pekka T. Lehtinen in 1981, and is found in Africa.
Anansia is a monotypic genus of Angolan araneomorph spiders in the family Tetrablemmidae containing the single species, Anansia astaroth. It was first described by Pekka T. Lehtinen in 1981, and is found in Angola.
Bacillemma is a monotypic genus of Thai araneomorph spiders in the family Tetrablemmidae containing the single species, Bacillemma leclerci. It was first described by Christa Laetitia Deeleman-Reinhold in 1993, and is found in Thailand.
Choiroblemma is a genus of Indian araneomorph spiders in the family Tetrablemmidae that was first described by J. D. Bourne in 1980. As of September 2019 it contains two species, found in India: C. bengalense and C. rhinoxunum.
Cuangoblemma is a monotypic genus of Angolan araneomorph spiders in the family Tetrablemmidae containing the single species, Cuangoblemma machadoi. It was first described by Paolo Marcello Brignoli in 1974, and is found in Angola.
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.
Indicoblemma is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by J. D. Bourne in 1980. It is a senior synonym of Chavia.
Maijana is a monotypic genus of araneomorph spiders in the family Tetrablemmidae containing the single species, Maijana rackae. It was first described by Pekka T. Lehtinen in 1981 from a single female found in bat guano in a Javanese cave of the Bogor Regency. Though it looks similar to Tetrablemma species, the structural parts, namely the epigyne, are unique enough to differentiate them.
Mariblemma is a monotypic genus of araneomorph spiders in the family Tetrablemmidae found on the Seychelles. It contains the single species, Mariblemma pandani, first described by Paolo Brignoli in 1978 and placed into Paculla. Pekka T. Lehtinen transferred it to Mariblemma in 1981, disagreeing with Brignoli's original placement.
Micromatta is a monotypic genus of Central American araneomorph spiders in the family Tetrablemmidae found in Belize. It contains the single species, Micromatta atoma, first described by W. A. Shear in 1978. Pekka T. Lehtinen transferred it to Micromatta in 1981 because the shapes of the male embolus and conductor are quite different than those of Matta and Caraimatta. Additionally, the plesiomorphic structure of pedipalp segments prove that the three genera aren't a paraphyletic group.
Paculla is a genus of araneomorph spiders in the family Pacullidae that was first described by Eugène Louis Simon in 1887. Originally placed with the Tetrablemmidae, it was transferred to the Pacullidae after a 2017 genetic study.
Rhinoblemma is a monotypic genus of araneomorph spiders in the family Tetrablemmidae found on Caroline Island. It contains the single species, Rhinoblemma unicorne, first described in 1963 by Carl Friedrich Roewer under the name Tetrablemma unicornis. In 1981, Pekka T. Lehtinen transferred it to Rhinoblemma.
Singalangia is a monotypic genus of Sumatran araneomorph spiders in the family Tetrablemmidae containing the single species, Singalangia sternalis. It was first described by Pekka T. Lehtinen in 1981, and is found on Sumatra.
Singaporemma is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Anagrina is a genus of African long-spinneret ground spiders that was first described by Lucien Berland in 1920. As of June 2019 it contains only two species, found only in Africa: A. alticola and A. nigritibialis.
Matta is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by C. R. Crosby in 1934.
