Plectreurid spiders (family "Plectreuridae") belong to a small family confined to the North American deserts and the island of Cuba. Only two genera are known - the nominate genus "Plectreurys" and "Kibramoa". These ecribellate (lacking a plate-like wooly silk-producing structure anterior to the spinnerets on the venter), haplogyne spiders build haphazard webs under rocks and dead cacti. Relatively little is known of their biology. Unlike the sicariids, scytodids and diguetids, to which they are related, they have eight eyes. In appearance females of "Plectreurys" resemble those of the larger species of the cribellate Filistatidae. They differ in their eye arrangement and in having the first femora (third leg segment from the body) bowed.
