Rubrepeira is a genus of orb-weaver spiders containing the single species, Rubrepeira rubronigra. It was first described by Herbert Walter Levi in 1992, [2] found from Mexico to Brazil. [1]
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
Orb-weaver spiders or araneids are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields and forest. "Orb" can in English mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Eriophora is a genus of orb-weaver spiders first described by Eugène Simon in 1895. It occurs in the Americas, Australasia, and Africa. The name is derived from Ancient Greek roots, and means "wool bearing".
Psechridae is a family of araneomorph spiders with about 70 species in two genera. These are among the biggest cribellate spiders with body lengths up to 2 centimetres (0.79 in) and funnel webs more than 1 metre in diameter.
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.
Bertrana is a genus of Central and South American orb-weaver spiders first described by Eugen von Keyserling in 1884. It includes some of the smallest known araneid orb-weavers. Bertrana striolata females are 4.5 mm long or less. The eight eyes are in two rows. The abdomen is white on top and on the sides, with multiple hieroglyphic-like lines and bars of many different shapes and length. In females, these are red, in males, black.
Kaira, sometimes called frilled orbweavers, is a mostly neotropical genus of orb-weaver spiders first described by O. Pickard-Cambridge in 1889. It includes sixteen described species that occur from South America up to the southern and eastern USA. It is presumably related to Aculepeira, Amazonepeira and Metepeira.
Acacesia is a genus of orb-weaver spiders first described by Eugène Simon in 1895. It contains six species with a mostly neotropical distribution, ranging from South America to Mexico. One species, A. hamata, is found in the US as well.
Testudinaria is a genus of orb-weaver spiders first described by Władysław Taczanowski in 1879.
Parawixia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. Most species are found in the Neotropics but one species, Parawixia dehaani, is found in Australasia and tropical Asia as far west as India.
Alcimosphenus is a monotypic genus of Caribbean long-jawed orb-weavers containing the single species, Alcimosphenus licinus. It was first described by Eugène Louis Simon in 1895, and is found in the Caribbean. It was transferred to the Araneidae in 1951, but was returned here in 2005.
Metleucauge is a genus of long-jawed orb-weavers that was first described by Herbert Walter Levi in 1980.
Mollemeta is a monotypic genus of long-jawed orb-weavers endemic to Chile. It contains the single species, Mollemeta edwardsi, first described as Landana edwardsi, based on a female found in 1904. The name is a reference to "Molle", the Mapudungun word for "tree", because it builds its vertical orb webs on tree trunks. It is in a clade with Allende, Chrysometa, Dolichognatha, Meta, and Metellina due to several autapomorphies, including the unique shapes of the cymbium, conductor, and embolus.
Opas is a genus of long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1896. Though few males have ever been studied, they are much smaller than females. Their pedipalps have a paracymbium, and a conductor that projects from the tegulum, enclosing the embolus. They sit at the center of orb-shaped webs, many attached to low plants. Their webs are relatively flat, though rotated 45 degrees from horizontal. It has previously been synonymized with Leucauge.
Amazonepeira is a genus of South American orb-weaver spiders first described by Herbert Walter Levi in 1989.
Pronous is a genus of South American and African orb-weaver spiders first described by Eugen von Keyserling in 1881.
Spinepeira is a genus of South American orb-weaver spiders containing the single species, Spinepeira schlingeri. It was first described by Herbert Walter Levi in 1995, and has only been found in Peru.
Tatepeira is a genus of Central and South American orb-weaver spiders first described by Herbert Walter Levi in 1995.
Spintharidius is a genus of orb-weaver spiders first described by Eugène Simon in 1893. As of April 2019 it contains only two species found in South America and the Caribbean.
Singa, also called striped orb-weavers, is a genus of orb-weaver spiders first described by C. L. Koch in 1836. They are small for orb-weavers, reaching 6 millimetres (0.24 in) or less in body length, excluding the legs.
