Ogulnius is a genus of ray spiders that was first described by Octavius Pickard-Cambridge in 1882. [2]
As of June 2020 [update] it contains eighteen species, found in the Caribbean, South America, Asia, and Panama: [1]
In synonymy:
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 600 species in over 50 genera worldwide.
Theridiosomatidae, commonly known as Ray Spiders, are a family of araneomorph spiders first described by Eugène Simon in 1881. The family includes 137 species divided between 20 genera. They are most recognizable for their construction of cone-shaped webs.
Theridiosoma is a genus of ray spiders that was first described by Octavius Pickard-Cambridge in 1879. They use their web as a high speed slingshot to actively hunt for prey.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena.
Cryptachaea is a genus of spiders in the Theridiidae family.
Linothele is a genus of curtain web spiders that was first described by Ferdinand Karsch in 1879. All but one of the described species are from South America. The exception is L. septentrionalis from the far-away Bahamas, although it has certain features that suggest it may belong in another genus. Additionally, an undescribed species of Linothele is known from Panama.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Phoroncidia is a genus of comb-footed spiders that was first described by J. O. Westwood in 1835.
Ochyrocera is a genus of midget ground weavers that was first described by Eugène Louis Simon in 1892.
Metazygia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. They physically resemble members of Nuctenea, but they do not have fine setae on the carapace.
Sphecozone is a genus of sheet weavers that was first described by Octavius Pickard-Cambridge in 1871.
Neospintharus is a genus of comb-footed spiders that was first described by H. Exline in 1950. It was synonymized with Argyrodes in 1962, but revalidated in 2004.
Chthonos is a genus of South American ray spiders that was created by Jonathan A. Coddington in 1986 because the previous name was preoccupied. Originally placed with the Orb-weaver_spiders under the name Tecmessa, it was transferred to the ray spiders in 1986.
Naatlo is a genus of ray spiders that was first described by Jonathan A. Coddington in 1986.
Wendilgarda is a genus of ray spiders that was first described by Eugen von Keyserling in 1886.
