Tetrablemmidae, sometimes called armored spiders, is a family of tropical araneomorph spiders first described by Octavius Pickard-Cambridge in 1873.[1] It contains 126 described species in 29 genera from southeast Asia, with a few that occur in Africa and Central and South America.[2] Pacullidae was incorporated into this family in 1981,[3] but was later restored as a separate family in a 2016 phylogenetic study.[4]

Most species have been collected from litter and soil, including that of epiphytes. Some live in caves and show typical adaptations of cave spiders, such as loss of eyes and weak sclerotization.[5][6] Members of Tetrablemma only have four eyes,[1] a trait in spiders only found in these and certain members of Caponiidae.
