Tetrablemma is a widespread genus of armored spiders first described by Octavius Pickard-Cambridge in 1873. It contains 30 species found in tropical and subtropical regions primarily throughout Asia and Oceania, with one species, Tetrablemma rhinoceros, known from Angola. They are found in 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.
