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.
Pekka T. Lehtinen is a Finnish arachnologist and taxonomist. He is known for his works in systematics and for the many expeditions in which he has participated.
Brignoliella is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Pahanga diyaluma, is a species of spider of the genus Pahanga. It is endemic to Sri Lanka. It was first described from Diyaluma Falls area, hence the specific name.
Pahanga is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1979.
Shearella lilawati is a species of spider of the genus Shearella. It is endemic to Sri Lanka. The specific name refers to Queen Lilawati, who reigned intermittently between 1197 and 1212 in Polonnaruwa, Sri Lanka.
Shearella is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by Pekka T. Lehtinen in 1981.
Shearella selvarani is a species of spiders of the genus Shearella. It is endemic to Sri Lanka.
Tetrablemma medioculatum is a species of spider of the genus Tetrablemma. The nominate subspecies is endemic to Sri Lanka. Two other subspecies can be found, both of which are endemic to India.
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.
Caraimatta is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Pekka T. Lehtinen in 1981.
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.
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.
Sulaimania is a genus of Southeast Asian araneomorph spiders in the family Tetrablemmidae that was first described by Pekka T. Lehtinen in 1981. As of September 2019 it contains two species, found in Malaysia and Singapore: S. brevis and S. vigelandi.
