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.
Neoleptoneta is a genus of North American leptonetids that was first described by Paolo Marcello Brignoli in 1972.
Pacullidae is a family of araneomorph spiders first described by Eugène Simon in 1894. It was merged into Tetrablemmidae in 1958, then raised back to family status after a large phylogenetic study in 2017.
Tetrablemma is a widespread genus of armored spiders first described by Octavius Pickard-Cambridge in 1873. It only has four eyes; an unusual trait for spiders, found only here and in some species of Caponiidae, though the two are not closely related. The eyes are large, but unequal in size, closely grouped around the center of the prosoma that rises in a somewhat of a cone shape from the abdomen. They have four closely positioned spinnerets enclosed in a corneous casing.
Harpactea is a genus of woodlouse hunting spiders that was first described by W. S. Bristowe in 1939. They are non-web building predators that forage on the ground and on tree trunks at night, mainly in xerothermic forests. During the day, they hide in silk retreats they build under rocks or bark.
Speocera is a genus of six eyed spiders in the family Ochyroceratidae, containing fifty one species.
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.
Metanapis is a genus of araneomorph spiders in the family Anapidae, first described by Paolo Brignoli in 1981.
Pseudanapis is a genus of araneomorph spiders in the family Anapidae, first described by Eugène Simon in 1905. It is a senior synonym of "Gossiblemma" and "Amrishoonops".
Ablemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Carl Friedrich Roewer in 1963.
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.
Caraimatta is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Pekka T. Lehtinen in 1981.
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.
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.
Lamania is a genus of Southeast Asian araneomorph spiders in the family Pacullidae that was first described by Pekka T. Lehtinen in 1981. Originally placed with the armored spiders, it was moved to the Pacullidae in 2017.
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.
Monoblemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Carl Eduard Adolph Gerstaecker in 1941.
