Tetrablemmidae
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. 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. Members of '' Tetrablemma'' only have four eyes, a trait in spiders only found in these and certain members of Caponiidae. Genera , the World Spider Catalog accepts the following genera: *'' Ablemma'' Roewer, 1963 — Papua New Guinea, Asia *'' Afroblemma'' Lehtinen, 1981 — Angola, Tanzania, Congo *'' Anansia'' Lehtinen, 1981 — Angola *'' Bacillemma'' Deeleman-Reinhold, 1993 — ...

Tetrablemma
''Tetrablemma'' is a widespread genus of Tetrablemmidae, armored spiders first described by Octavius Pickard-Cambridge in 1873. It contains 30 species found in Tropics, tropical and Subtropics, subtropical regions primarily throughout Asia and Oceania, with one species, ''Tetrablemma rhinoceros'', known from Angola. They are found in Plant litter, leaf litter, soil, and caves. The genus contains some of the only species of spiders to have just four eyes along with some species of Caponiidae, to which they are not closely related. The eyes are large and unequal in size, closely grouped around the center of the cephalothorax, with the eye group tending to be set further back in males. The genus contains some variation in eye arrangement, as ''Tetrablemma alaus'', a subterranean species, lacks eyes or any eye spots entirely. They have four closely positioned spinnerets enclosed in a corneous casing. Pekka T. Lehtinen, Lehtinen divided the genus into three subgenera in 1981: ''Ku ...
