Storena is a genus of ant spiders first described by Charles Athanase Walckenaer in 1805. [2]
Members of this genus are medium to large spiders with exoskeletons that may be smooth or granulated in texture, lightly covered with hairs. The colour of the carapace ranges from reddish orange to dark chestnut-brown or black, usually darker around the eyes. The legs are orange to red, sometimes darkening towards the tarsi. The abdomen exhibits 2, 3, or 5 yellow or orange spots on the upper surface, with the unpaired spot (when present) positioned above the spinnerets and a brown pitted shield sitting between the spots. The eyes are circular and split across three rows, with two eyes in the bottom row, four in the middle, and two in the top row. [3]
As of August 2020 [update] it contains 55 species: [1]
Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found in all tropical and subtropical regions of South America, Africa, Madagascar, Australia-New Guinea, New Zealand, Arabia and the Indian subcontinent. Most species are daytime hunters and live together with ants, mimicking their behavior and sometimes even their chemical traits. Although little is known about most zodariids, members of the genus Zodarion apparently feed only on ants; a number of other genera in the family are apparently also ant specialists.
Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks.
Dolomedes is a genus of large spiders of the family Pisauridae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all Dolomedes species are semiaquatic, with the exception of the tree-dwelling D. albineus of the southeastern United States. Many species have a striking pale stripe down each side of the body.
Habronestes is an ant-eating spider genus that occurs only in Australia.
Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and it contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them. The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning "jaw". Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands. One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.
Isopeda is a genus of huntsman spiders that was first described by Ludwig Carl Christian Koch in 1875.
Desis is a genus of intertidal spiders that was first described by Charles Athanase Walckenaer in 1837. Species of the genus are found in Australasia, the Pacific, Japan, eastern and southern Africa, and India. They are marine spiders, living in the intertidal zone and only emerging at the ebb tide to hunt for invertebrates including shrimp. When submerged during high tides, they stay in an air chamber sealed with silk, and breathe its air.
