Loxosceles arizonica, known as the Arizona brown spider, [2] is a species of spider in the family Sicariidae. [1] Field studies suggest that ants are its major prey, especially ants of the genera Novomessor and Camponotus . [3]
The brown recluse, Loxosceles reclusa, Sicariidae is a recluse spider with a necrotic venom. Similar to other recluse spider bites, their bite sometimes requires medical attention. The brown recluse is one of three spiders with medically significant venom in North America.
The recluse spiders, 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. They are venomous spiders known for their bite, which sometimes produces a characteristic set of symptoms known as loxoscelism.
Habronattus is a genus in the family Salticidae. Most species are native to North America. They are commonly referred to as paradise spiders due to their colorful courtship ornaments and complex dances, similar to birds-of-paradise.
The Chilean recluse spider is a highly venomous spider, Loxosceles laeta, of the family Sicariidae. In Spanish, it is known as araña de rincón, or "corner spider"; in Portuguese, as aranha-marrom or "brown spider". It is considered by many to be the most dangerous of recluse spiders, and its bites often result in serious systemic reactions, even death.
Cesonia is a genus of ground spiders that was first described by Eugène Simon in 1893.
Diguetia is a genus of coneweb spiders that was first described by Eugène Simon in 1895. Members of this genus are six-eyed spiders that are either white or patterned. They are common in the southwestern United States and Mexico, and one species is found in Argentina. In the United States, species have been found in Arizona, California, Nevada, New Mexico, and Texas. These spiders build a tubular retreat at the tip of their tent-like webs. Once an insect is caught in the web, the spider bites it and injects venom to stop its prey from moving, later wrapping it in silk. Both males and females use stridulation while mating, with females also stridulating when harassed. Two species of jumping spiders feed on its eggs. There are eleven Diguetia species.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Psilochorus is a genus of spiders in the family Pholcidae.
Loxosceles deserta, commonly known as the desert recluse, is a brown spider of the family Sicariidae.
Ummidia is a genus of mygalomorph spiders in the family Halonoproctidae, and was first described by Tamerlan Thorell in 1875.
Cicurina, also called the cave meshweaver, is a genus of dwarf sheet spiders that was first described by Anton Menge in 1871. Originally placed with the funnel weavers, it was moved to the Dictynidae in 1967, then to the Hahniidae in 2017. The name is from the Latin root "cucur-", meaning "to tame".
Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.
Argennina is a monotypic genus of North American cribellate araneomorph spiders in the family Dictynidae containing the single species, Argennina unica. It was first described by Willis J. Gertsch & S. Mulaik in 1936, and has only been found in Texas. Individuals are around 5 mm (0.20 in) in body length. The carapace is a pale yellow brown, sparsely covered with short black hairs, and the abdomen is gray to pale yellow with fine pale hairs.
Emblyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by R. V. Chamberlin in 1948.
Phantyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by R. V. Chamberlin in 1948.
Tricholathys is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by R. V. Chamberlin & Wilton Ivie in 1935.
Grammonota is a genus of dwarf spiders that was first described by James Henry Emerton in 1882.
Hentziectypus is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. Originally placed with Theridion, it was moved to Achaearanea in 1955, and to its own genus in 2008. These spiders most resemble members of Cryptachaea, but are distinguished by a median apophysis that is broadly attached to the tegulum. Spiders of Parasteatoda have a median apophysis attached to the embolus, while those of Achaearanea have a hooked paracymbium on the pedipalps of males.
