Idiops is a genus of armored trapdoor spiders that was first described by Josef Anton Maximilian Perty in 1833. [6] It is the type genus of the spurred trapdoor spiders, Idiopidae. Idiops is also the most species-rich genus of the family, and is found at widely separated locations in the Neotropics, Afrotropics, Indomalaya and the Middle East. [7] Females live in tubular burrows lined with a thick layer of white silk. These typically have a D-shaped lid that fits into the entrance like a cork, and some burrows have two entrances. [8] The lid may consist of mud, moss or lichen, which is bound below by a thick layer of silk. As in all genera of this family, the anterior lateral eyes (ALE) are situated near the clypeal margin, far in front of the remaining six eyes, which are arranged in a tight group. [9] The males which are smaller in size, wander about or occasionally live in burrows. [10] Like other mygalomorphs, they are relatively large and long-lived. Forest clearance and agricultural practices that loosen the soil and enhance erosion, besides soil removal for brick making have been pointed out as serious threats to some Indian species. [8] Species ranges are poorly known – in India for instance, most species are known only from their type localities. [7]

<span class="mw-page-title-main">Ground spider</span> Family of spiders

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.

<span class="mw-page-title-main">Nemesiidae</span> Family of spiders

Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae".

<i>Lycosa</i> Genus of spiders

Lycosa is a genus of wolf spiders distributed throughout most of the world. Sometimes called the "true tarantula", though not closely related to the spiders most commonly called tarantulas today, Lycosa spp. can be distinguished from common wolf spiders by their relatively large size. This genus includes the European Lycosa tarantula, which was once associated with tarantism, a dubious affliction whose symptoms included shaking, cold sweats, and a high fever, asserted to be curable only by the traditional tarantella dance. No scientific substantiation of that myth is known; the venom of Lycosa spiders is generally not harmful.

<i>Hogna</i> Genus of spiders

Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.

<i>Allocosa</i> Genus of spiders

Allocosa is a spider genus of the wolf spider family, Lycosidae. The 130 or more recognized species are spread worldwide.

Heligmomerus is a genus of armored trapdoor spiders that was first described by Eugène Louis Simon in 1892.

<i>Olios</i> Genus of spiders

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.

<i>Ctenus</i> Genus of spiders

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, Ctenus medius has been shown to share some toxic properties with 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 some species in the genus may have a medically significant venom. The venom of C. medius interferes with 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.

Ancylotrypa is a genus of African wafer trapdoor spiders that was first described by Eugène Simon in 1889. Originally placed with the Ctenizidae, it was moved to the Cyrtaucheniidae in 1953.
