Cithaeron is a genus of araneomorph spiders in the family Cithaeronidae, first described by O. Pickard-Cambridge in 1872. [2]
As of April 2019 [update] it contains seven species: [1]
The spider genus Steatoda, in the family Theridiidae, includes about 120 recognized species, distributed around the world. One common name is cupboard spider, for many species build their webs in dark, sheltered, undisturbed places around the house or garden, in sheds and garages, under garden furniture, compost bins, and the like. Signs of the cupboard spider include small white spots of spider droppings, like small splashes of paint, on the floor underneath the web.
Cithaeronidae is a small family of araneomorph spiders first described by Simon in 1893 Female Cithaeron are about 5 to 7 millimetres long, males about 4 millimetres (0.16 in).
Trochanteriidae is a family of spiders first described by Ferdinand Karsch in 1879 containing about 180 species in 21 genera. Most are endemic to Australia though Doliomalus and Trochanteria are from South America and Olin and Plator are from Asia. Platyoides species exist in southern and eastern Africa, Madagascar, and the Canary Islands with one species, P. walteri, introduced to Australia.
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. The name is a reference to the backwardly directed process on the cymbium of the male palp. The species epithet is derived from the Greek Ancient Greek: χείρ, romanized: cheir, meaning "hand", and Acanthium, a genus of thorny-stemmed plants.
Drassodes is a genus of ground spiders that was first described by Niklas Westring in 1851. They are brown, gray, and red spiders that live under rocks or bark in mostly dry habitats, and are generally 3.8 to 11.6 millimetres long, but can reach up to 20 millimetres (0.79 in) in length.
Castianeira is a genus of ant-like corinnid sac spiders first described by Eugen von Keyserling in 1879. They are found in Eurasia, Africa, and the Americas, but are absent from Australia. Twenty-six species are native to North America, and at least twice as many are native to Mexico and Central America.
Chorizopes is a genus of orb-weaver spiders first described by O. Pickard-Cambridge in 1871. Though it belongs to the orb weaver family, these spiders move through leaf litter preying on other spiders rather than spinning webs. The original name was "Chorizoopes", but the emendation Chorizopes by Tamerlan Thorell is now protected by usage.
Dolichognatha is a genus of tropical and subtropical long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1869. Originally placed with the Archaeidae, it was transferred to the Araneidae in 1967, and to the Tetragnathidae in 1981.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Camillina is a genus of ground spiders that was first described by Lucien Berland in 1919. They are very similar to sister genus Zelotes.
Idiops is a genus of armored trapdoor spiders that was first described by Josef Anton Maximilian Perty in 1833. 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. 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. 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. The males which are smaller in size, wander about or occasionally live in burrows. 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. Species ranges are poorly known – in India for instance, most species are known only from their type localities.
Anyphaena is a genus of anyphaenid sac spiders first described by Carl Jakob Sundevall in 1833.
Inthaeron is a monotypic genus of Asian araneomorph spiders in the family Cithaeronidae, containing the single species, Inthaeron rossi. It was first described by Norman I. Platnick in 1991, and has only been found in India. Females can be distinguished from those of its sister genus, Cithaeron, by the arrangement of cylindrical gland spigots on the posterior median spinnerets, appearing in two rows rather than in clusters. The name is derived from "India", the country it was first found in, and "Cithaeron", the name of the other genus of Cithaeronidae.
Chasmocephalon is a genus of Australian araneomorph spiders in the family Anapidae, first described by O. Pickard-Cambridge in 1889.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
Setaphis is a genus of ground spiders that was first described by Eugène Simon in 1893.
Synaphosus is a genus of ground spiders that was first described by Norman I. Platnick & M. U. Shadab in 1980.
Rhomphaea is a genus of comb-footed spiders that was first described by Ludwig Carl Christian Koch in 1872.
