Tord Tamerlan Teodor Thorell (3 May 1830 – 22 December 1901) [1] was a Swedish arachnologist.
Thorell studied spiders with Giacomo Doria at the Museo Civico di Storia Naturale de Genoa. He corresponded with other arachnologists, such as Octavius Pickard-Cambridge, Eugène Simon and Thomas Workman.
He described more than 1,000 spider species during his time from the 1850s to 1900.
Thorell wrote: On European Spiders (1869) and Synonym of European Spiders (1870-73).
The Orb-weaver spider genus Thorellina and the jumping spider genus Thorelliola are named after him, as well as about 30 species of spiders:
Bathippus is a genus of jumping spiders.
Chrysilla is a genus of jumping spiders that was first described by Tamerlan Thorell in 1887. Several species formerly placed here were transferred to Phintella, and vice versa. Females are 3 to 4 millimetres long, and males are 4 to 9 millimetres long. The genus is Persian, derived from the Greek Χρύσιλλα.
Simaetha is a genus of Australasian jumping spiders that was first described by Tamerlan Thorell in 1881. They resemble members of Simaethula and Stertinius.
Viciria is a genus of jumping spiders that was first described by Tamerlan Thorell in 1877.
Gelotia is a genus of jumping spiders that was first described by Tamerlan Thorell in 1890.
Nephilengys is a genus of tropical spiders of the family Nephilidae, consisting of two currently described species. The genus Nephilingis has been split off from this genus. Both genera have been called hermit spiders from the habit staying in their retreats during the day; the name eunuch spiders has been used for Nephilengys alone. Males may sever parts of their palpal bulbs after copulation.
Ohilimia is a spider genus of the jumping spider family, Salticidae.
Cethegus is a genus of mygalomorph spiders in the curtain-web family Euagridae. It s endemic to Australia and was first described by Tamerlan Thorell in 1881.
Holconia is a genus of Southern Pacific huntsman spiders that was first described by Tamerlan Dahls Thorell in 1877. It was branched from Isopeda in 1990.

Lipocrea is a genus of orb-weaver spiders first described by Tamerlan Thorell in 1878.
Cantikus v-notatus is a species of spider in the family Pholcidae. It is found from Myanmar to Indonesia.
Cycais is a genus of Asian corinnid sac spiders first described by Tamerlan Thorell in 1877. As of April 2019 it contains only two species, one from Sulawesi and one from Japan.
Creugas is a genus of corinnid sac spiders first described by Tamerlan Thorell in 1878.
Conothele is a genus of mygalomorph spiders in the family Halonoproctidae, first described by Tamerlan Thorell in 1878. Originally placed with the Ctenizidae, it was moved to the Halonoproctidae in 2018.
Artoria is a genus of spiders in the family Lycosidae. It was first described in 1877 by Tamerlan Thorell, and the type species is Artoria parvula. In 1960, Roewer erected the genera Artoriella and Trabeola. However, in 2002, Volker Framenau reviewed Artoria and synonymised both these genera with Artoria.
Sphedanus is a genus of Asian nursery web spiders that was first described by Tamerlan Thorell in 1877. As of June 2019 it contains only three species, found only in Asia: S. banna, S. quadrimaculatus, and S. undatus.
Nyctimus is a genus of crab spiders first described by Tamerlan Thorell in 1877. As of April 2019 it contains only two species.
Asceua elegans is a species of spiders in the family Zodariidae. It is the type species of the genus. It is found in Myanmar.
Talaus elegans is a species of crab spiders in the family Thomisidae. It is found in Sumatra.
Eutittha is a genus of spiders in the family Cheiracanthiidae. It was first described by Tamerlan Thorell in 1878.
