The redback spider, also known as the Australian black widow, is a species of highly venomous spider believed to originate in South Australia or adjacent Western Australian deserts, but now found throughout Australia, Southeast Asia and New Zealand, with colonies elsewhere outside Australia. It is a member of the cosmopolitan genus Latrodectus, the widow spiders. The adult female is easily recognised by her spherical black body with a prominent red stripe on the upper side of her abdomen and an hourglass-shaped red/orange streak on the underside. Females usually have a body length of about 10 millimetres (0.4 in), while the male is much smaller, being only 3–4 mm (0.12–0.16 in) long.
Austracantha is a genus of spider with a single species, Austracantha minax, commonly known as the jewel spider or the Christmas spider. It is a member of the family Araneidae and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around 12 mm (0.47 in) for females, and 5 mm (0.20 in) for males. Their abdomen has six distinctive projections ("spines") that makes them easy to identify. They are predominantly a shiny black, with variable white, yellow, and orange patterns. Melanistic forms also occur during autumn. They are facultatively gregarious, and can be found in large aggregations of overlapping orb webs. They feed on small flying insects that get entangled in their webs. They are harmless to humans, though the webs can be a nuisance for bushwalkers. They are most abundant during the summer months.
The Sydney funnel-web spider is a species of venomous mygalomorph spider native to eastern Australia, usually found within a 100 km (62 mi) radius of Sydney. It is a member of a group of spiders known as Australian funnel-web spiders. Its bite is capable of causing serious illness or death in humans if left untreated.
Jotus is a spider genus of the family Salticidae, native to Australia, New Zealand, and Indonesia. There are thought to be many as yet undescribed species in southern Australia.
Maratus is a spider genus of the family Salticidae. These spiders are commonly referred to as peacock spiders due to the males' colorful and usually iridescent patterns on the upper surface of the abdomen often enhanced with lateral flaps or bristles, which they display during courtship. 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.
Saitis is a genus of jumping spiders that was first described by Eugène Louis Simon in 1876. The Australian species may belong to other genera, such as Maratus.
Maratus volans is a species in the jumping spider family (Salticidae), belonging to the genus Maratus. These spiders are native to certain areas in Australia and occupy a wide distribution of habitats. They have a specialized visual system that allows them to see the full visible spectrum as well as in the ultraviolet-range; this helps them detect and pursue prey. Males of this species are characterized by their colourful abdomen flaps that are used to attract females during courtship.
Nephila pilipes is a species of golden orb-web spider. It resides all over countries in East and Southeast Asia as well as Oceania. It is commonly found in primary and secondary forests and gardens. Females are large and grow to a body size of 30–50 mm, with males growing to 5–6 mm. It is the second largest of the orb-weaving spiders apart from the recently discovered Nephila komaci. The first, second, and fourth pairs of legs of juvenile females have dense hairy brushes, but these brushes disappear as the spider matures.
Saitis barbipes is a common jumping spider found in the Mediterranean region.
Heteropoda davidbowie is a species of huntsman spider of the genus Heteropoda. It was described from the Cameron Highlands District in peninsular Malaysia and named in honour of singer David Bowie.
Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats. Adult spiders measure between 3 and 4.5 mm in length. The cephalothorax and abdomen are bronze to black in color, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae and front femora. Like many jumping spiders, Z. sexpunctatus males exhibit ritualized courtship and agonistic behavior.
Peckhamia is a peer-reviewed, open-access, scientific journal covering research on jumping spiders. It is published by the Peckham Society, an international organization of naturalists and scientists with an interest in jumping spiders, named in honor of George and Elizabeth Peckham. The journal was established in 1977 and its current editor-in-chief is David E. Hill.
Trogloraptor is a genus of large spiders found in the caves of southwestern Oregon. It is the sole genus in the family Trogloraptoridae, and includes only one species, Trogloraptor marchingtoni. These spiders are predominantly yellow-brown in color with a maximum leg span of 3 in (7.6 cm). They are remarkable for having hook-like claws on the raptorial last segments of their legs.
Maratus speciosus, sometimes called the coastal peacock spider, is an Australian species of jumping spider. They are only known to inhabit the vegetation of the coastal sand dunes of southwestern Western Australia. Like other Maratus spiders, the males of the species engage in a courtship display during which they raise their third pair of legs and their abdomen, presenting their colourful opisthosomal plate to potential female partners. Accompanying their elaborate dance moves, males beat their front and back body halves together, sending vibrations that travel through the ground which the females pick up, stimulating them into receiving higher chances of a successful mate. Unlike other Maratus, however, the males of this species have a set of bright orange hairs (setae) along both edges of the opisthosoma which only become visible during this display. Maratus speciosus derives from the arachnid class with both sexes measuring about 5 mm in body length, equivalent to a pencil eraser. They are known as the smallest species of spiders. This organism is known as diurnal cursorial hunters, meaning they feed on insects. Like any other jumping spider, they rely on their keen vision and jumping actions to help them travel and spot prey at far distances.
Maratus jactatus is a species of the genus Maratus, an Australian member of the jumping spider family. Maratus jactatus are from the jumping spider group Salticidae. The name jactatus is Latin for rocking - derived from their signature mating rituals. Maratus jactatus have the ability to jump lengths up to 50 times their size. They have been collected only in Wondul Range National Park in southern Queensland. The sparklemuffin are very small spiders that range from being four to six millimeters in length, similar to the length of a grain of rice. The males are close to four and one half millimeters long, which is smaller compared to the female who are about five and three tenths millimeters long.
Maratus sceletus is a species of the genus Maratus, an Australian member of the jumping spider family. Described in 2015, they have been collected only in Wondul Range National Park in southern Queensland. The species name is derived from the Latin sceletus "skeleton", from its distinctive body pattern. Maratus sceletus is a small species, from 3.7 to 4.7 mm long. The male is black with prominent white stripes and markings across its carapace and legs.
Maratus pavonis is a species of jumping spider (Salticidae), endemic to Australia, where it is found in Western Australia, New South Wales, Victoria and Tasmania. The species epithet, pavonis, derives from the Latin, pavo, pavonis, meaning "peacock".
Maratus mungaich, the banksia peacock spider, is a species of jumping spider in the family Salticidae. It is endemic to Western Australia.
Saitis insectus is a species of spider in the genus Saitis and the family, Salticidae. It is found in central Australia.
Jotus remus is a species of spider in the family Salticidae, found in Australia. It was first described in 2016. Males of Jotus remus are distinguished from other species in the genus Jotus by the presence of "paddles" formed by long bristles (setae) on the metatarsus and tarsus of the third pair of legs. The paddles are flattened parallel to the male's body. They are used to attract females by waving them over the edge of a leaf while the male is on the opposite side to the female. The female initially attempts to attack the paddle, but males are skillful at avoiding such attacks. Eventually the female ceases to attack, and the male is able to move to the female's side of the leaf and mate rapidly. Females are difficult to distinguish from those of other Jotus species.
