Embrik Strand was an entomologist and arachnologist who classified many insect and spider species including the greenbottle blue tarantula.
Aruana is a genus of jumping spiders that was first described by Embrik Strand in 1911. As of June 2019 it contains only two species, found only in Papua New Guinea and on the Aru Islands: A. silvicola and A. vanstraeleni.
Thianella is a possible monotypic genus of jumping spiders containing the single species, Thianella disjuncta. It was first described by Embrik Strand in 1907, and is found only on Java. Based on a male specimen, Roewer placed it close to Thiania, but his placements of salticids have often been questionable and no drawings currently exist. The name is an alteration of the salticid genus Thiania, and the species name is from Latin disiunctus "separated". The World Spider Catalog regards the genus and species names as nomina dubia.
Prodidominae is a family of spider, sometimes called long-spinneret ground spiders. It was formerly regarded as a subfamily of Gnaphosidae, but was raised to a family in 2022.
Prochora praticola is a species of spider in the family Miturgidae. It is found in China, Korea, and Japan, and was first described by Friedrich Wilhelm Bösenberg and Embrik Strand in 1906 as Agroeca praticola.
Bassaniana, commonly called bark crab spiders, is a widespread genus of crab spiders that was first described by Embrik Strand in 1928.
Anepsion is a genus of orb-weaver spiders first described by Embrik Strand in 1929.
Cybaeopsis is a genus of tangled nest spiders first described by Embrik Strand in 1907, and transferred from Agelenidae to Amaurobiidae by Pekka T. Lehtinen in 1967. They all occur in North America except for C. typica, found in Russia and Japan.
Aethrodiscus is a genus of African orb-weaver spiders containing the single species, Aethrodiscus transversalis. It was first described by Embrik Strand in 1913, and has only been found in Central Africa.
Sagellula is a genus of east Asian huntsman spiders that was first described by Embrik Strand in 1942. It was originally described under the name "Sagella", but this was changed to Sagellula when a senior homonym was discovered. As of September 2019 it contains two species, found in China and Japan: S. octomunita and S. xizangensis.
Allomengea is a genus of dwarf spiders that was first described by Embrik Strand in 1912.
Bolephthyphantes is a genus of dwarf spiders that was first described by Embrik Strand in 1901. As of May 2019 it contains only three species: B. caucasicus, B. index, and B. indexoides.
Estrandia is a monotypic genus of dwarf spiders containing the single species, Estrandia grandaeva. It was first described by H. H. Blauvelt in 1936, and has only been found in China, Japan, and Russia.
Papakula is a monotypic genus of nursery web spiders containing the single species, Papakula niveopunctata. It was first described by Embrik Strand in 1911, and is only found on the Aru Islands.
Tapinothelella is a monotypic genus of South African nursery web spiders containing the single species, Tapinothelella laboriosa. It was first described by Embrik Strand in 1909, and is only found in South Africa.
Oreonetides is a genus of dwarf spiders that was first described by Embrik Strand in 1901.
Ummeliata is a genus of Asian sheet weavers that was first described by Embrik Strand in 1942.
Phintella abnormis is a spider species of the family Salticidae.
Cyrtarachne nagasakiensis is a species of spider in the orb-weaver spider family Araneidae, found in Pakistan, India, China, Korea and Japan. Spiders in the genus Cyrtarachne construct "spanning-thread webs" rather than the more typical orb webs of the family Araneidae. These webs have a small number of radii and instead of a tight spiral of sticky threads, the sticky spanning threads are widely spaced and do not form a spiral. When prey is caught on one of the spanning threads, one end comes loose, and the prey, often a moth, dangles from the other end until hauled in by the spider.
Cyrtarachne yunoharuensis is a species of spider in the orb-weaver spider family Araneidae, found in China, Korea and Japan. Spiders in the genus Cyrtarachne construct "spanning-thread webs" rather than the more typical orb webs of the family Araneidae. These webs have a small number of radii and instead of a tight spiral of sticky threads, the sticky spanning threads are widely spaced and do not form a spiral. When prey is caught on one of the spanning threads, one end comes loose, and the prey, often a moth, dangles from the other end until hauled in by the spider.
