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.
Stenochilidae is a family of southeast Asian araneomorph spiders that produce ecribellate silk. First described by Tamerlan Thorell in 1873, it now contains twelve described species in two genera.
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.
Wildlife of Sri Lanka includes its flora and fauna and their natural habitats. Sri Lanka has one of the highest rates of biological endemism in the world.
Pandava is a genus of araneomorph spiders in the family Titanoecidae.
Campostichomma is a genus of spiders in the family Udubidae native to Sri Lanka. Many of its species were moved to either Griswoldia or Devendra. This genus was originally placed in the family Agelenidae. It was moved to Miturgidae in 1967, to Zoropsidae in 1999, then to Udubidae in 2015.
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.
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.
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.
Zoica is a genus of wolf spiders in the family Lycosidae, containing twelve species.
Aprusia is a genus of goblin spiders in the family Oonopidae, containing five accepted species. four species are endemic to Sri Lanka and the other species is endemic to India.
Olios lamarcki, is a species of spider of the genus Olios. It is found in Madagascar to Sri Lanka and India. The subspecies O. lamarcki taprobanicus is endemic to Sri Lanka.
Epidius is a genus of crab spiders that was first described by Tamerlan Thorell in 1877. It is a senior synonym of Pothaeus.
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.
