Females lack these bright colors, being cryptic in appearance. In at least one species, ''Maratus vespertilio'', the expansion of the flaps also occurs during ritualised contests between males. The male display and courtship dance are complex, involving visual and vibratory signals. All species of ''Maratus'' are found in Australia.

Several species in this genus were earlier classified in the genus ''Saitis'', containing the Mediterranean ''Saitis barbipes'', which is superficially similar to ''Maratus'' (colorful males with an enlarged third pair of legs). ''Saitis'' in Australia have enlarged and fringed third legs which they use for display, but do not raise their abdomens like ''Maratus''.<ref name=OttoHill2012b/>

''M. furvus'' from China was described in 1992 in the genus ''Lycidas'', and became part of ''Maratus'' when ''Lycidas'' was synonymized in 2012. It was moved to ''Euochin'' in 2023.<ref>{{cite web |title=''Euochin furva'' (Song & Chai, 1992) |work=World Spider Catalog |publisher=Natural History Museum Bern |url=https://wsc.nmbe.ch/spec-data/37176 |access-date=22 April 2026 }}</ref>

== Description == ''Maratus'' species are small spiders, with a total body length mostly around 4–5 mm (0.2 in), sometimes smaller, with a high degree of sexual dimorphism. They are known as peacock spiders, based on the peacock-like display of the dorsal (upper) surface of the abdomen (opisthosoma) of the males, on which there is a "plate" or "fan" of usually brightly colored and highly iridescent scales and hairs, often forming patterns in which the foreground colors contrast with the iridescent background. There may in addition be "flaps" or dense fringes of hairs at the sides of the abdomen, sometimes brightly colored. In both sexes, the abdomen is joined to the cephalothorax by a long and very flexible pedicel. This allows males to raise their abdomens, which may also be capable of being flattened and waved from side to side,<ref>{{Cite web|url=https://www.abc.net.au/news/2016-05-27/sydney-scientists-adorable-peacock-spider-discovery/7443800|title = 'Arachnophobes love them': Sydney scientist's 'adorable' dancing spider discovery| website=Australian Broadcasting Corporation |date = 27 May 2016}}</ref> thus emphasizing the appearance of the dorsal pattern. Not all species have colors that appear bright to human vision; ''Maratus vespertilio'' is relatively cryptically colored, with most iridescence on the lateral flaps.<ref name=OttoHill2012b/> The abdominal display is used in courtship and, in at least one species, also in aggressive interactions with rival males. If the male continues his dance when the female is not interested, she will often attempt to attack, kill, and feed on him; she may also do this after mating (sexual cannibalism).<ref name=OttoHill2012a/> If the female is already mated, then she will appear more aggressive, and less receptive to other males' displays. This can also occur if the female simply was not impressed by the male (less vibrations or less leg waving). She has an anti-receptivity signal that tells males she is not receptive. This serves a function to both the males and females. The males will stop wasting their energy on an unwilling female. The male's display is likely to attract predators, so stopping the performance is likely to protect both the female and male from potential dangers.<ref>{{Cite journal|last1=Girard|first1=Madeline B.|last2=Elias|first2=Damian O.|last3=Kasumovic|first3=Michael M.|date=2015-12-07|title=Female preference for multi-modal courtship: multiple signals are important for male mating success in peacock spiders|url=|journal=Proceedings of the Royal Society B: Biological Sciences|language=en|volume=282|issue=1820|article-number=20152222|doi=10.1098/rspb.2015.2222|issn=0962-8452|pmc=4685782|pmid=26631566}}</ref> In almost all species, males have relatively long third legs, often brightly patterned, that are also used in courtship displays.<ref name=OttoHill2012b/> Salticid spiders have excellent vision, with the ability to see in at least two colors: green and ultraviolet (UV).<ref name=HarlJack00/><ref name=ZureCronTaylByrn15/> The male display includes vibratory signals in addition to visual ones.<ref name=Girard-2014/> At least one species (''Maratus fimbriatus'') displays with its first pair of legs rather than its third pair.<ref>{{Cite journal|last=Otto & Hill|first=Jurgen|date=10 February 2016|title=Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)|url=https://peckhamia.com/peckhamia_numbers.html|journal=Peckhamia|volume=136|issue=1}}</ref> Some ''Maratus'' including ''Maratus calcitrans'', ''Maratus digitatus'' and ''Maratus jactatus'' display with greatly enlarged and decorated spinnerets when their abdomen is elevated.<ref>Otto, J.

Male palpal bulbs are relatively simple in appearance, with a circular embolus, and are rather similar in different species. The palp usually has a simple retrolateral tibial apophysis with a blunt tip.<ref name=OttoHill2012b/>

In contrast to the brightly coloured and distinctive males, females are cryptic or camouflaged in appearance, with mottled patterns of whitish and brownish scales. The epigyne is simple, with a pair of circular "windows" (fossae) to the front and a pair of oval spermathecae to the rear. The long and flexible pedicel allows females to rotate their abdomens by more than 180° during mating.<ref name=OttoHill2012b/>

== Mechanisms used in colour production == Male ''Maratus'' species mostly display the brilliantly coloured upper surface of their abdomen, often with extensions and fringes, to the females in courtship dances. Colours are produced by two main methods using scales (or modified hairs).<ref>Video: Science has uncovered the colour secret of the amazing Australian peacock spider [https://web.archive.org/web/20160811203143/http://www.businessinsider.com.au/video-science-has-uncovered-the-colour-secret-of-the-amazing-australian-peacock-spider-2016-8]</ref> One mechanism uses pigments to produce reds, whites, and creams in barbed scales that help scatter light. To produce blues the spiders use arrays of nanostructures reflecting light of particular wavelengths, in the case of ''Maratus splendens'' a shiny, sometimes violet blue. The nanostructures are embedded in flat, convex, sac-like scales, amplifying reflected light, according to University of Groningen's Doekele Stavenga. This is the only animal where this kind of reflection has been shown.<ref>Splendid coloration of the peacock spider Maratus splendens Doekele G. Stavenga, Jürgen C. Otto, Bodo D. Wilts Published 10 August 2016.DOI: 10.1098/rsif.2016.0437 http://rsif.royalsocietypublishing.org/content/13/121/20160437</ref> Stavenga compared Maratus colours with patterns on butterfly wings, the colors of flowers, and the feathers of the parotia bird. The blues produced by nanostructures in ''Maratus'' do not fade over time, unlike the normal pigmenting method. Other blue animals, like beetles, are rare but also use nanostructures. Nathan Morehouse of the University of Pittsburgh found ''Maratus volans'' have four different photoreceptors (tetrachromats) allowing them to see red, blue, green, and ultraviolet and also resolve the intricacies of the male's display designs.<ref>[https://web.archive.org/web/20160811132937/http://news.nationalgeographic.com/2016/08/peacock-spiders-animals-science-colors/ Weird & Wild How Peacock Spiders Get Their Bright Blue 'Butts']</ref><ref>Blue spider scales aren't what they seem http://bioinspired-materials.ch/research/research-stories/blue-spider-scales-arent-what-they-seem</ref><ref>Australian peacock spiders: New form of colour in male peacock spiders baffles scientists http://www.trans66.com/australian-peacock-spiders-new-form-of-colour-in-male-peacock-spiders-baffles-scientists/34017/</ref>

== Taxonomy == The genus ''Maratus'' was first described by Ferdinand Karsch in 1878.<ref name=WSC_g2767 /> Karsch was a curator at the Museum für Naturkunde, Berlin, and named spiders and other animals from preserved specimens collected by others. He described the species ''Maratus amabilis'', the type of his new genus, on the basis of a single male specimen, whose origin was only recorded as "Australia". His short description mentioned the abdomen being flattened and quadrangular in shape, but otherwise did not refer to the characteristic abdominal "flaps". In a footnote, he also named ''Maratus amoenus'' (now ''M. volans'').<ref name=Karsch1878 /> {{Interlanguage link|Marek Żabka|pl}} in 1987 was the first to restore Karsch's two species of ''Maratus'',<ref name=Zabk87 /> and moving more previously described species to the genus in 1991.<ref name=OttoHill2011 /> ''Maratus'' was greatly expanded in the 21st century, both by known species being moved to ''Maratus'' and by the description of new species. Most of the new species have been described by Jürgen C. Otto and David E. Hill.<ref name=WSC_g2767 />

Otto and Hill suggest that ''Maratus'' is closely related to the genus ''Saitis''. Both are found in Australia, and in both genera the males have elongated third legs and unmodified first legs.<ref name=OttoHill2012b/>

=== Phylogeny === The relationships among ''Maratus'' and related genera are unclear, and many species await description. Otto and Hill synonymized ''Lycidas'' with ''Maratus'') in 2012 recognising the type species for ''Lycidas'', ''Lycidas anomalus'' was actually a ''Maratus'', thus causing all then named ''Lycidas'' to be subsumed by ''Maratus''.<ref name=OttoHill2012b/> They hypothesize that the remaining genera may be related as shown below:<ref name=OttoHill2012b/> {{clade |style=font-size:100%;line-height:110% |label1=''Saitis'' sensu Zhang 2012 |1={{clade |label1=''Jotus'' group |1={{clade |1=''Jotus'' |2=''Prostheclina''}} |label2=''Saitis'' group |2={{clade |1=''Saitis'' |label2=''Maratus'' group |2={{clade |1='''''Maratus''''' |2=''Hypoblemum''}} }} }} }} One molecular phylogenetic study, by Junxia Zhang in 2012, concluded that the seven Australian genera ''Hypoblemum'', ''Jotus'', ''Lycidas'', ''Maileus'', ''Maratus'', ''Saitis'' and ''Prostheclina'' were so closely related that they could all be accommodated in ''Saitis'' but this suggestion has not been carried through to any taxonomic publication. In the ''Saitis'' group, the third leg is longer and the first leg unspecialized. In the ''Jotus'' group the first leg is longer and specialized. In both ''Maratus'' and some ''Hypoblemum'' in the ''Maratus'' group, the abdomen is raised during courtship, but only ''Maratus'' has a colorful dorsal plate.<ref name=OttoHill2012b/>

=== Nomenclature === Early scientific names mostly used Latin or Greek descriptors, for example the type species ''Maratus amabilis'' (1878) refers to the friendly or pleasant ''Maratus''. ''Maratus volans'' (1874) means the flying ''Maratus'', reflecting the mistaken belief this species (and indeed the genus) could fly by means of its extended abdominal flap. We now know they cannot fly and the flap is used in courtship or (in at least one case) ritualised combat. ''Maratus chrysomelas'' refers to the golden yellow iridescence of the abdomen when viewed at some angles. In 1947 Dunn used the species name ''pavonis'' meaning peacock. Zabka and Waldock continued the tradition of using Latin and Greek in the 1980s and 1990s as did Otto & Hill from 2011 on, also using a patronym for Stuart Harris in the case of ''Maratus harrisi''. As peacock spiders became more popular, so did patronyms, with ''Maratus purcellae'' for its discoverer Otto & Hill 2013 and ''Maratus proszynski'' for Jerzy Prószyński Waldock 2015. Common names featured in news media gained traction, particularly with 'Sparklemuffin' for ''Maratus jactatus''. In July 2016, Barbara Baehr and Robert Whyte from the Queensland Museum announced a newly discovered species to be named ''Maratus licunxin'' or ''Maratus licunxini'' after the artistic director of the Queensland Ballet, Li Cunxin<ref>[http://www.arts.qld.gov.au/news/6176-new-peacock-spider "New dancing spider named for dancing icon"], Arts Queensland, 11 July 2016</ref> and honoured Jürgen Otto with ''Maratus ottoi'', Michael Duncan and Michael Doe with ''Maratus michaelorum'', and Julianne Waldock with ''Maratus julianneae''.<ref name=":0">{{Cite journal |last=Baehr & Whyte |year=2016 |title=The Peacock Spiders (Araneae: Salticidae: Maratus) of the Queensland Museum, including six new species |journal=Zootaxa |volume=4154 |issue=5 |pages=501–525 |doi=10.11646/zootaxa.4154.5.1 |pmid=27615856}}</ref>

''Maratus splendens'' and ''Maratus rainbowi'' refer to the same, single species, both listed here. Otto & Hill, when describing the female for the first time chose to continue to use Rainbow's ''Maratus splendens'' rather than Roewer's replacement name ''Maratus rainbowi''. While ''Maratus rainbowi'' still appears in a number of on-line catalogs, all published descriptions and studies of this spider to date have used the original name ''Maratus splendens'', the replacement name never having gained currency, and no longer preoccupied.<ref name="Otto2014d">Otto, J.
