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.
Philodromidae, also known as philodromid crab spiders and running crab spiders, is a family of araneomorph spiders first described by Tord Tamerlan Teodor Thorell in 1870. It contains over 500 species in thirty genera.
Misumena is a genus of crab spiders sometimes referred to as flower crab spiders. They are similar in appearance to several other genera in the family Thomisidae, such as Misumenoides and Mecaphesa.
Misumenops is a common genus of crab spider with more than 50 described species.
Misumenoides is a genus of spiders in the family Thomisidae. Spiders in this family are commonly called "crab" or "flower" spiders.
Noegus is a genus of jumping spiders that was first described by Eugène Louis Simon in 1900.
Aphantochilus is a genus of ant-mimicking crab spiders that was first described by Octavius Pickard-Cambridge in 1871. As of June 2020 it contains three species, found in Paraguay, Brazil, Argentina, and Panama: A. cambridgei, A. inermipes, and A. rogersi. It is a senior synonym of Cryptoceroides.
Mesabolivar is a genus of cellar spiders that was first described by M. A. González-Sponga in 1998.
Acentroscelus is a genus of South American crab spiders that was first described by Eugène Louis Simon in 1886. It is a senior synonym of Whittickius.
Ceraarachne is a genus of South American crab spiders that was first described by Eugen von Keyserling in 1880.
Epicadinus is a genus of crab spiders that was first described by Eugène Louis Simon in 1895.
Epicadus is a genus of crab spiders that was first described by Eugène Louis Simon in 1895. It is considered a senior synonym of Tobias.
Erissoides is a genus of South American crab spiders that was first described by Cândido Firmino de Mello-Leitão in 1929. As of September 2020 it contains two species, both found in Brazil: E. striatus and E. vittatus.
Erissus is a genus of South American crab spiders that was first described by Eugène Louis Simon in 1895.
Onocolus is a genus of South American crab spiders first described by Eugène Simon in 1895. It is considered a senior synonym of Paronocolus.
Stephanopis is a genus of crab spiders first described by Octavius Pickard-Cambridge in 1869. It was erected for five then newly described species, including S. altifrons, from Australia. Stephanopis was characterized by the high cephalic region with unequally sized anterior eyes disposed in a strongly recurved row, opisthosoma ending in several spiniform projections and dorsoventrally depressed habitus. According to Pickard-Cambridge, the single specimen used for the description of S. altifrons was dry-pinned. Therefore the specimen could not be properly examined, so it was not possible to determine if the specimen was adult. Moreover, he states his own sketch of the spider as “hasty” or "dull". This may explain why the somatic characters were inadequately described, genitalic features were not mentioned at all, and the illustrations were not detailed enough, making the species unidentifiable.
Titidius is a genus of spiders in the family Thomisidae. It was first described in 1895 by Eugène Simon. As of 2017, it contains 20 species.
Matinta is a genus of South American jumping spiders. The largest number of species are found in Brazil.
Stephanopis altifrons is a species of crab spider found in Australia. The body length may reach up to 10 and 6 mm in the female and male, respectively. The colour is usually brown, or shades of grey, and sometimes black. The egg sac is 7.5 mm in diameter. Often hidden in crevices of tree bark, it is irregular in shape and camouflaged with the debris. Eggs are off-white, 25 to 30 in number. The female rests with the eggs. The food of this spider appears to be other spiders. Recorded prey include members of the families Salticidae and Hersiliidae.
Paratobias is a monotypic genus of Central American crab spiders containing the single species, Paratobias championi. It was first described by Frederick Octavius Pickard-Cambridge in 1900, and it has only been found in Panama. Eugène Simon synonymized it with Stephanopis in 1903 due to several similarities to the genus, but Machado & Teixeira revalidated the genus in 2021, citing the distinctive trapezoidal shape of the abdomen as well as several differences in eye morphology.
