Pandercetes is a genus of huntsman spiders that was first described by Ludwig Carl Christian Koch in his 1875 treatise on Australian spiders. [2] They are mainly distributed in tropical Asia and Australia, and are known for their cryptic coloration that matches local moss and lichen. Their legs have lateral hairs, giving them a feathery appearance, further masking their outline against tree trunks. Their head is somewhat elevated and the carapace has the thoracic region low and flat. [3]
The genus is characterized by the internal anatomy of the reproductive structures. Males have irregular coils at the terminal end, while females have screw like copulatory ducts. [4]
As of October 2019 [update] it contains sixteen species and one subspecies, found in tropical forests in Asia, extending east to Australia: [1]
The genus Argiope includes rather large spiders that often have a strikingly coloured abdomen. These spiders are distributed throughout the world. Most countries in tropical or temperate climates host one or more species that are similar in appearance. The etymology of Argiope is from a Latin word argentum meaning silver. The carapace of Argiope species is typically covered in silvery hairs, and when crawling in the sun, they reflect it in a way that gives them a metallic, white appearance.
Huntsman spiders, members of the family Sparassidae, are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places. In southern Africa the genus Palystes are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related.
Gasteracantha is a genus of orb-weaver spiders first named by Carl Jakob Sundevall in 1833. Species of the genus are known as spiny-backed orb-weavers, spiny orb-weavers, or spiny spiders. The females of most species are brightly colored with six prominent spines on their broad, hardened, shell-like abdomens. The name Gasteracantha is derived from the Greek gaster (γαστήρ), meaning "belly, abdomen", and akantha (άκανθα), meaning "thorn, spine". Spiny-backed orb-weavers are sometimes colloquially called "crab spiders" because of their shape, but they are not closely related to the true crab spiders. Other colloquial names for certain species include thorn spider, star spider, kite spider, or jewel spider.
Plexippus is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846. It is considered a senior synonym of Hissarinus and Apamamia.
Cheiracanthium, commonly called yellow sac spiders, is a genus of araneomorph spiders in the family Cheiracanthiidae, and was first described by Carl Ludwig Koch in 1839. They are usually pale in colour, and have an abdomen that can range from yellow to beige. Both sexes range in size from 5 to 10 millimetres. They are unique among common house spiders because their tarsi do not point either outward, like members of Tegenaria, or inward, like members of Araneus), making them easier to identify.
Selenocosmia is a genus of tarantulas that was first described by Anton Ausserer in 1871. The genus is found in China, New Guinea, Australia, Indonesia, Myanmar, Malaysia, Laos, Vietnam, Philippines, India and Pakistan. They are commonly referred to as whistling or barking spiders, due to their ability to stridulate using lyra hairs.
Heteropoda is a genus of spiders in the family Sparassidae, the huntsman spiders. They are mainly distributed in tropical Asia and Australia, while at least one species, H. venatoria, has a cosmopolitan distribution, and H. variegata occurs in the Mediterranean.
Cyrtophora, the tent-web spiders, is a genus of orb-weaver spiders first described by Eugène Simon in 1895. Although they are in the "orb weaver" family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimetres (0.39 in) long. Some members, including Cyrtophora cicatrosa, exhibit the ability to change colour rapidly.
Thelcticopis is a genus of huntsman spiders that occurs almost exclusively in the area India to Japan to New Guinea and Fiji. However, one species occurs in Costa Rica, and another in Congo basin, although the latter species is probably misplaced in this genus.
Olios is the largest genus of huntsman spiders, containing 166 species. They are found throughout the world, with most species occurring in hot countries. The genus was first described by Charles Athanase Walckenaer in 1837.
Cyrtarachne is a genus of orb-weaver spiders first described by Tamerlan Thorell in 1868.
Oxyopes is a genus of lynx spiders found worldwide. It includes arounds 300 species and is classified under the lynx spider family Oxyopidae. Like other lynx spiders, they are easily recognizable by the six larger eyes arranged hexagonally on top of the head (prosoma), with the remaining smaller two eyes in front. They are also characterized by long spine-like bristles (setae) on their legs. They are ambush predators, actively hunting prey by sight. Though they produce and use silk, they do not build webs to capture prey.
Bowie is a genus of Ctenidae that was described by Peter Jäger in 2022. The genus was named after the English singer-songwriter and actor David Bowie and currently encompasses 107 species, 55 of which were named after elements from David Bowie's musical catalogue.
