Loxosceles deserta, commonly known as the desert recluse, is a recluse spider of the family Sicariidae. [1] It is found in Mexico and the United States. The desert recluse is commonly misidentified as L. unicolor (of South America) [2] or as L. reclusa (the brown recluse of the southern and midwestern states), two spiders which do not live anywhere near the vicinity.
The recluse spiders (Loxosceles (/ l ɒ k ˈ s ɒ s ɪ l iː z /), also known as brown spiders, fiddle-backs, violin spiders, and reapers, is a genus of spiders that was first described by R. T. Lowe in 1832. [4] They are venomous spiders known for their bite, which sometimes produces a characteristic set of symptoms known as loxoscelism.
Loxosceles, commonly known as "recluse spiders" or "violin spiders", are distributed nearly worldwide in warmer areas. Hexophthalma and Sicarius, commonly known as "sand spiders" or "assassin spiders", live in the deserts of southern Africa and South to Central America, respectively. [1]
Other spiders in western states that might possibly cause necrotic injuries are the hobo spider, desert recluse spider, and the yellow sac spider. For example, the venom of the hobo spider , a common European species now established in the northwestern United States and southern British Columbia , has been reported to produce similar symptoms ...

There have been documented cases of homes having very large populations of brown recluse spiders for many years without any of the human inhabitants being bitten. For this reason, L. reclusa bites are relatively rare, but, because its range overlaps human habitation, its bite is the cause of loxoscelism in North America.
The Chilean recluse spider, Loxosceles laeta, is a highly venomous spider of the family Sicariidae. In Spanish, it (and other South American recluse spiders) is known as araña de rincón, or "corner spider"; in Brazilian Portuguese, as aranha-marrom or "brown spider". It is considered by many to be the most dangerous of recluse spiders, and ...
As well as the Chilean recluse spider, the venom of Loxosceles intermedia has a high concentration of the enzyme sphingomyelinase D. [5] responsible for local and systemic effects, and is one of the main species attributed to deaths in South America, since the systemic effects of the bite occur frequently. The symptoms are not immediate, which ...
