Andasta is a genus of ray spiders that was first described by Eugène Louis Simon in 1895. [2]
As of June 2020 [update] it contains four species, found in Asia and on the Seychelles: [1]
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.
Thwaitesia is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1881.
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.
Argyrodella is a monotypic genus of Seychelloise comb-footed spiders containing the single species, Argyrodella pusillus. It was first described by Michael I. Saaristo in 2006, and is found on the Seychelles.
Zoma zoma is a species of ray spider that is endemic to Silhouette Island of Seychelles. It was first described by Michael I. Saaristo & A. V. Tanasevitch in 1996. To date Zoma only contains its type species Zoma Zoma. The name of Zoma refers to the belt of silvery corpuscles on the abdomen of the type species. Not much is known about males of the species. Females have a total length, not including chelicerae, of 1.79 mm. It is threatened by habitat degradation from invasive plants, such as Cinnamomum verum.
Pleorotus was a monotypic genus of Seychelloise huntsman spiders containing the single species, Pleorotus braueri. It was first described by Eugène Louis Simon in 1898, and was endemic to the Seychelles. The description was based on a single male collected on Mahe Island in 1894, but none have been found in later collections, and it has been declared extinct.
Zoma is a genus of ray spiders that was first described by Michael I. Saaristo in 1996. As of June 2020 it contains three species, found in Japan, China, and on the Seychelles: Z. dibaiyin, Z. fascia, and Z. zoma.
Metanapis is a genus of araneomorph spiders in the family Anapidae, first described by Paolo Brignoli in 1981.
Prasonica is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
Rhacocnemis is a monotypic genus of Seychelloise huntsman spiders containing the single species, Rhacocnemis guttatus. It was first described by Eugène Louis Simon in 1897, and is endemic to the Seychelles.
Rhomphaea is a genus of comb-footed spiders that was first described by Ludwig Carl Christian Koch in 1872.
Sesato is a monotypic genus of African comb-footed spiders containing the single species, Sesato setosa. It was first described by Michael I. Saaristo in 2006, and is found on the Seychelles.
Seycellesa is a genus of spiders in the family Theridiidae. It consists of only its type species: Seycellesa braueri, which is endangered and endemic to the Seychelles.
Spinembolia is a monotypic genus of African comb-footed spiders containing the single species, Spinembolia clabnum. It was first described by Michael I. Saaristo in 2006, and is found on the Seychelles.
Stoda is a monotypic genus of African comb-footed spiders containing the single species, Stoda libudum. It was first described by Michael I. Saaristo in 2006, and is found on the Seychelles.
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.
Wendilgarda is a genus of ray spiders that was first described by Eugen von Keyserling in 1886.
Michael I. Saaristo was a Finnish arachnologist, with a particular interest in the spiders of the Seychelles. The World Spider Catalog lists 61 genus names or synonyms and 109 species names or synonyms of which he is the sole or co-author.
Firmicus is a genus of crab spiders that was first described by Eugène Louis Simon in 1895.
