Australomisidia is a genus of spiders in the family Thomisidae. It was first described in 2014 by Szymkowiak. As of 2017 [update] , it contains 8 species, all from Australia. [1]
Australomisidia comprises the following species: [1]
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.
Xysticus is a genus of ground crab spiders described by C. L. Koch in 1835, belonging to the order Araneae, family Thomisidae. The genus name is derived from the Ancient Greek root xyst, meaning "scraped, scraper".
Diaea is a genus of crab spiders first described by Tamerlan Thorell in 1869. Most species are found in specific locations except for D. livens, which occurs in the United States and D. dorsata, which has a palearctic distribution. Adults are 5 millimetres (0.20 in) to 7 millimetres (0.28 in) and tend to hide in and around vegetation, especially flowers, where their color allows them to blend in to their surroundings.
The genus Oxytate, commonly known as grass crab spiders, comprises a homogenous group of nocturnal crab spiders. The complete mitochondrial genome of the type species O. striatipes was determined in 2014.
Zygometis is a genus of spider in the family Thomisidae described by Simon in 1901, containing the sole species Zygometis xanthogaster, or the milky flower spider or white flower spider, with a distribution from Thailand to Australia. They are ambush predators.
Cymbacha is a genus of crab spiders that was first described by Ludwig Carl Christian Koch in 1874.
Bassaniodes is a genus of crab spiders that was first described by Reginald Innes Pocock in 1903.
Cetratus is a genus of South Pacific crab spiders that was first described by Władysław Kulczyński in 1911.
Corynethrix is a monotypic genus of South Pacific crab spiders containing the single species, Corynethrix obscura. It was first described by Ludwig Carl Christian Koch in 1876 based on a female specimen. They have been found in New South Wales and Queensland. A male has not yet been identified, and there is very little known about the biology and behaviour of this species and its relatives.
Hedana is a genus of crab spiders that was first described by Ludwig Carl Christian Koch in 1874.
Porropis is a genus of spiders in the family Thomisidae. It was first described in 1876 by L. Koch. As of 2017, it contains 6 species.
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.
Tharpyna is a genus of spiders in the family Thomisidae. It was first described in 1874 by L. Koch. As of 2017, it contains 12 species from Australia, India, and Indonesia.
Tharrhalea is a genus of crab spiders first described in 1875 by Ludwig Carl Christian Koch.
Boomerangiana is a monotypic genus of Australian crab spiders in the tribe Misumenini containing the single species, Boomerangiana dimidiata. They are small white spiders, only 2 to 3 millimetres long, with silvery round abdomen. The species was originally described in 1867 by Ludwig Koch from an immature female found in Brisbane. Though he originally placed it with Xysticus, after several more were found in Rockhampton and Gayndah and more information became available, he moved the species to Diaea. It was moved to its own genus in 2014 named Boomerangia, but was renamed Boomerangiana when it was discovered that the name was already in use for a family of nematodes.
Isala punctata is a species of South Pacific crab spiders. It is the only species in the monotypic genus Isala. It was first described by Ludwig Carl Christian Koch in 1876, and is found in Australia.
Australomisidia elegans is a species of spiders in the family Thomisidae. It is found in Australia.
Bomis is a genus of very small crab spiders, first described by German arachnologist Ludwig Carl Christian Koch in 1874. Five species are currently described, with three species from India and two from Australia.
Australomisidia cruentata, one of the crab spiders, is a small spider found in Australia. The body length of the female is up to 5 mm, the male 3 mm. An ambush predator, often seen on flowers in the Pultenaea group of egg and bacon plants, belonging to the pea family. The egg sac is also laid on the flowers. Petals being fastened with silk in a chamber. The spider stays with the eggs, probably still hunting from the entrance of the retreat, with the egg sac nearby. Prey is small flying insects. The genus Australomisidia was created in 2014, the word being a combination of Australia and Thomisidae, the crab spiders.
Spiracme is a genus of crab spiders erected by Anton Menge in 1876 to contain S. striata, transferred from Xysticus. The exact relationship of these spiders and their closest relatives has been long debated, and many included species have been transferred to and from similar genera, namely Xysticus and Ozyptila. Most recently, Rainer Breitling conducted a DNA barcoding study in 2019 and grouped similar species based on the results:
