The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders.
Sicariidae is a family of six-eyed venomous spiders known for their potentially necrotic bites. The family consists of three genera and about 160 species. Well known spiders in this family include the brown recluse spider and the six-eyed sand spider.
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Misumenoides is a genus of spiders in the family Thomisidae. Spiders in this family are commonly called "crab" or "flower" spiders.
Cosmophasis is a genus of spiders in the family Salticidae. They are predominantly Southeast Asian, while some species occur in Africa and Australia. Although most species more or less mimic ants, there are also colorful species that follow a different strategy.
Argyrodes, also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864. They occur worldwide, and are best known for their kleptoparasitism. They can spin their own webs, but tend to invade and reside in their hosts' webs. This relationship can be commensal or even mutual if the dewdrop spider feeds on small trapped insects that are not eaten by the host. Some species can even prey upon the host.
Hetschkia is a monotypic genus of Brazilian comb-footed spiders containing the single species, Hetschkia gracilis. It was first described by Eugen von Keyserling in 1886, and is found in Brazil.
Wirada is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1886.
Thwaitesia is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1881.
Cryptachaea is a genus of spiders in the Theridiidae family.
Olios is the largest genus of huntsman spiders, containing 166 species. They are found throughout the world, with most species occurring in hot countries. The genus was first described by Charles Athanase Walckenaer in 1837.
Emertonella is a genus of comb-footed spiders that was first described by E. B. Bryant in 1945.
Phoroncidia is a genus of comb-footed spiders that was first described by J. O. Westwood in 1835.
Taczanowskia is a genus of orb-weaver spiders first described by Eugen von Keyserling in 1879. Contrary to the common name of the group, spiders of the genus Taczanowskia do not build webs and are furtive hunters, deceiving their prey by producing sex pheromones that attract male moths, and catching their prey by using a pair of enlarged claws at the tip of their anterior legs.
Asagena is a genus of comb-footed spiders that was first described by Carl Jakob Sundevall in 1833.
Audifia is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884. As of May 2020 it contains three species, found in Africa and Brazil: A. duodecimpunctata, A. laevithorax, and A. semigranosa.
Helvibis is a genus of spiders in the family Theridiidae that was first described by Eugen von Keyserling in 1884. It is a senior synonym of Formicinoides.
Chthonos is a genus of South American ray spiders that was created by Jonathan A. Coddington in 1986 because the previous name was preoccupied. Originally placed with the Orb-weaver_spiders under the name Tecmessa, it was transferred to the ray spiders in 1986.
Cryptachaea gigantipes, known vernacularly as the white porch spider, is a species of cobweb spider in the family Theridiidae. It is native to south-eastern Australia and is an introduced species in New Zealand.
