Pterinochilus is a genus of baboon spiders that was first described by Reginald Innes Pocock in 1897. [3] They are found all throughout Africa
As of July 2022 [update] it contains ten species, all found in Africa: [1]
Ground spiders comprise Gnaphosidae, the seventh largest spider family with over 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include Gnaphosa, Drassodes, Micaria, Cesonia, Zelotes and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans.
The Harpactirinae are a subfamily of tarantulas which are native to the continent of Africa. Like many Old World tarantulas, they have a relatively strong venom, and can inflict a painful bite.
Ceratogyrus is a genus of tarantulas found in southern Africa. They are commonly called horned baboons for the foveal horn found on the peltidium in some species.
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.
Moggridgea is a genus of spiders in the tree dwelling family, Migidae. The genus was first described by Octavius Pickard-Cambridge in 1875, who named the genus after naturalist John Traherne Moggridge.
Pachygnatha is a genus of long-jawed orb-weavers that was first described by Carl Jakob Sundevall in 1823.
Olios is the largest genus of huntsman spiders, containing 177 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.
Hysterocrates is a genus of African tarantulas that was first described by Eugène Louis Simon in 1892.
Ariadna is a genus of tube-dwelling spider.
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.
Ctenus is a genus of wandering spiders first described by Charles Athanase Walckenaer in 1805. It is widely distributed, from South America through Africa to East Asia. Little is known about the toxic potential of the genus Ctenus, however, it was recently discovered that the species Ctenus medius shares toxic properties with those presented by Phoneutria nigriventer, such as proteolytic, hyaluronidase and phospholipase activities, in addition to producing hyperalgesia and edema, the venom of C. medius also interferes with the complement system in concentrations in which the venom of P. nigriventer is inactive, indicating that this spider has a noxious venom to humans. The venom of C. medius causes an eleavage in the complement component 3 (C3) of the complement system, it affects the central factor of the cascades of the complement, and interferes with the lytic activity of this system, which causes stronger activation and consumption of the complement components. Unlike C. medius, the venom of P. nigriventer does not interfere with lytic activity.
Scotophaeus is a genus of ground spiders that was first described by Eugène Simon in 1893.
Augacephalus is a genus of harpacterine theraphosid spiders. It has three species, all of which are found in Africa.
Dresserus is a genus of African velvet spiders that was first described by Eugène Simon in 1876.
Diores is a genus of spiders in the family Zodariidae.
