Crevice weaver spiders (Filistatidae) comprise cribellate spiders with features that have been regarded as "primitive" for araneomorph spiders. They are weavers of funnel or tube webs. The family contains 18 genera and more than 120 described species worldwide.
Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider, banana huntsman spider or cane spider.
Misionella is a genus of South American crevice weavers that was first described by M. J. Ramírez & C. J. Grismado in 1997. In 2005 a spider fossil found in 15- to 20-million-year-old Miocene amber from the Dominican Republic was described as Misionella didicostae. A second specimen was discussed soon thereafter.
Phidippus audax, the bold jumper or bold jumping spider, is a common species of spider belonging to the genus Phidippus, a group of jumping spiders easily identified by their large eyes and their iridescent chelicerae. Like all jumping spiders, they have excellent stereoscopic vision that aids them in stalking prey and facilitates visual communication with potential mates during courting. Bold jumping spiders are native to North America and have been introduced to Hawaii, Nicobar Islands, Azores, and the Netherlands. They are typically black with a distinct white triangle on their abdomen.
Peucetia viridans, the green lynx spider, is a bright-green lynx spider usually found on green plants. It is the largest North American species in the family Oxyopidae. This spider is common in the southern U.S., Mexico, Central America, and in many West Indies islands, especially Jamaica.
The anatomy of spiders includes many characteristics shared with other arachnids. These characteristics include bodies divided into two tagmata, eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed.
Saitis barbipes is a common jumping spider found in the Mediterranean region.
Lyssomaninae is a subfamily of jumping spiders. It includes four genera, three from the New World.
Kukulcania arizonica, commonly called the Arizona black hole spider is a species of spider belonging to the family Filistatidae. As the scientific and common names suggest, this spider is found in Arizona, and the neighbouring US states of New Mexico, Nevada and California.
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.
Dolomedes tenebrosus or dark fishing spider is a fishing spider found in the United States and Canada.
Oxyopes salticus is a species of lynx spider, commonly known as the striped lynx spider, first described by Hentz in 1845. Its habitat tends to be grasses and leafy vegetation; grassy, weedy fields, and row crops.
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.
Tetragnatha montana, commonly known as the silver stretch spider, is a species of long-jawed orb weaver from the family Tetragnathidae that has a Palearctic distribution. It preys mostly on flies and mosquitoes. The name silver stretch spider refers to its shiny metallic colour and its habit of extending its legs into a stick like shape.
Icius mbitaensis is a species of jumping spider in the genus Icius that lives in Kenya. It was first described in 2011 by Wanda Wesołowska. The spider lives communally amongst other spiders and preys on insects. It is small, with a cephalothorax between 2.0 and 2.2 mm long and an abdomen 2.2 and 2.7 mm long. The female and male are similar in size and colouration of the carapace. The male abdomen is grey-brown with a faint pattern visible on some specimens. The female has a brown abdomen, sometimes more reddish-brown to the front, with some examples having a patch in the middle and spots to the back. The species is similar to other Icius spiders but differs in the size of the embolus and tibial apophysis of the male and the epigynal depression and pockets, seminal ducts and spermathecae of the female.
Stenaelurillus fuscatus is a species of jumping spider in the genus Stenaelurillus that lives in Kenya and Tanzania. The species was first identified in 2000 by Wanda Wesołowska & Anthony Russell-Smith, and named for the Latin word for darkish. The spider is medium-sized with a carapace between 2.5 and 3.2 mm long and an abdomen that is between 2.8 and 3.6 in in length. The female carapace is dark brown and has two white stripes and a pattern of a triangle and spots on the abdomen. The colouration is similarly dark but the patterns are less clear. The male abdomen is dominated by a dark scutum. The female is also darker overall, with brown rather than the yellow spinnerets and light brown chelicerae of the male. The male has a hook near the base of the embolus that differentiates it from other species in the genus, while the female's wide insemination ducts sets it apart from the similar Stenaelurillus darwini.
Trichonephila is a genus of orb-weaver spiders that was first described by Friedrich Dahl in 1911, as a subgenus of Nephila. Trichonephila was elevated to the level of genus by Kuntner et al. in 2019. The genus Trichonephila belongs to the Araneidae family, also known as the orb weavers. The family Araneidae belongs within the superfamily of Araneoidea, comprising 18 families. Araneidae family members can be identified by looking for three-clawed spiders that have eight eyes spanned across two sets which form a trapezoid shape, on webs with a sticky glue like feeling. The very diverse Araneidae family is most famously known for their elaborate webs they spin, which are webs made of concentric circles with spokes extending out from the center. In few species of the spiders, you can find a zigzag shape going down the center of the web. Identifying the species of these spiders is not easy with the eye alone, it breaks down into phylogenomic variations between their species best observed under a microscope. The genus Trichonephila, like all other spider species in the world, are all predators. Not a single spider exists that is solely a herbivore or a detrivore.
Entypesa andohahela is a species of spider in the family Entypesidae, endemic to Madagascar. It was first described by Sergei Zonstein in 2018. The specific name andohahela refers to the locality in which the first described specimen was found, Andohahela National Park in south-eastern Madagascar.
Notolinga is a monotypic genus of South American sheet weavers containing the single species, Notolinga fuegiana. It is a replacement name for Linga, already in use by a genus of molluscs. Eugène Simon described the first female in 1902 under the name "Neriene fuegiana", but the first male was not described until 2019. It has only been found in Argentina and on the Falkland Islands.
