subdivision = see textThe Tetrablemmidae are a spider family with 126 described species in 29 genera that occur throughout the world tropics. They are sometimes called "armored spiders".The family "Pacullidae", with the only genus "Paculla", has been incorporated into this family in 1981.
Most tetrablemmids have been collected from litter and soil, including soil in
epiphyte s; some live in caves. Some cave species, but also some soil inhabitants, show typical adaptations of cave spiders, such as loss of eyes and weak sclerotization Shear, W.A. (1978). Taxonomic notes on the armored spiders of the families Tetrablemmidae and Pacullidae. "American Museum novitates" 2650 [http://digitallibrary.amnh.org/dspace/bitstream/2246/2964/1/N2650.pdf PDF] - [http://digitallibrary.amnh.org/dspace/handle/2246/2964 Abstract] ] .Spiders in the genus "Paculla" are four to five times larger than other tetrablemmids. The genus "Tetrablemma" features only four eyes, a trait only shared with most species of the not closely related
Caponiidae .Tetrablemmids do not seem to build webs.
