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.
Loxoscelism (/ l ɒ k ˈ s ɒ s ɪ l ɪ z əm /) is a condition occasionally produced by the bite of the recluse spiders (genus Loxosceles).The area becomes dusky and a shallow open sore forms as the skin around the bite dies ().

Rarely, the venom is carried by the bloodstream, causing red blood cell destruction. The venom is identical in male and female spiders, but females can have almost twice the concentration of toxins.
