Loxosceles arizonica
Arizona brown spider, Arizona Recluse
Loxosceles arizonica, commonly known as the Arizona brown spider or Arizona Recluse, is a recluse spider species in the family Sicariidae. Field studies indicate that ants constitute its primary prey, particularly species in the genera Novomessor and Camponotus. Like other Loxosceles species, it possesses cytotoxic venom capable of causing necrotic lesions, though documented cases of envenomation in humans appear limited compared to more widespread relatives such as L. reclusa.

The species is native to the United States, with its common name suggesting association with the Big Bend region of Texas. Like other members of the genus Loxosceles, it possesses cytotoxic venom that can cause tissue necrosis in humans, though documented cases specific to this species are limited.
