Anyphaenidae is a family of araneomorph spiders, sometimes called anyphaenid sac spiders. They are distinguished from the sac spiders of the family Clubionidae and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. In most spiders the spiracle is just anterior to the spinnerets. Like clubionids, anyphaenids have eight eyes arranged in two rows, conical anterior spinnerets and are wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. There are more than 500 species in over 50 genera worldwide.
Philodromidae, also known as philodromid crab spiders and running crab spiders, is a family of araneomorph spiders first described by Tord Tamerlan Teodor Thorell in 1870. It contains over 600 species in thirty genera. Most are dull colored- brown, gray, yellowish or mottled with a leaf-like cardiac mark on the anterior dorsal abdomen, and seldom reach above 10 millimetres (0.39 in) long. None of the species build webs, but they do use silk for draglines and egg sacs.
Misumenops is a common genus of crab spider with more than 50 described species.
Misumenoides is a genus of spiders in the family Thomisidae. Spiders in this family are commonly called "crab" or "flower" spiders.
Castianeira is a genus of ant-like corinnid sac spiders first described by Eugen von Keyserling in 1879. They are found in Eurasia, Africa, and the Americas, but are absent from Australia. Twenty-six species are native to North America, and at least twice as many are native to Mexico and Central America.
Tmarus is a genus of crab spiders, comprising the following species:
Sillus is a genus of anyphaenid sac spiders first described by Frederick Octavius Pickard-Cambridge in 1900.
Senoculus is a genus of araneomorph spiders in the Senoculidae family, and was first described by Władysław Taczanowski in 1872. It is the only genus in the family Senoculidae.
Synema is a genus of spider in the family Thomisidae, found in most parts of the world.
Teudis is a genus of anyphaenid sac spiders first described by O. Pickard-Cambridge in 1896.
Isoctenus is a genus of South American wandering spiders first described by Philipp Bertkau in 1880.
Eustala is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
Hamataliwa is a genus of lynx spiders that was first described by Eugen von Keyserling in 1887.
Stephanopis is a genus of crab spiders first described by Octavius Pickard-Cambridge in 1869. The genus Stephanopis was erected for five newly described species, including S. altifrons, from Australia. Stephanopis was characterized by the high cephalic region with unequally sized anterior eyes disposed in a strongly recurved row, opisthosoma ending in several spiniform projections and dorsoventrally depressed habitus. According to Pickard-Cambridge, the single specimen used for the description of S. altifrons was dry-pinned. Therefore the specimen could not be properly examined, so it was not possible to determine if the specimen was adult. Moreover, he states his own sketch of the spider as “hasty”. This may explain why the somatic characters were inadequately described, genitalic features were not mentioned at all, and the illustrations were not detailed enough, making the species unidentifiable.
Arachosia is a genus of anyphaenid sac spiders that was first described by Octavius Pickard-Cambridge in 1882.
