Cryptachaea pusillana is a species of tangle web spider, family Theridiidae. It is only known from French Guiana. [1]
Latrodectus is a broadly distributed genus of spiders with several species that are commonly known as the true widows. This group is composed of those often loosely called black widow spiders, brown widow spiders, and similar spiders. However, the diversity of species is much greater. A member of the family Theridiidae, this genus contains 34 species, which include several North American "black widows". Besides these, North America also has the red widow Latrodectus bishopi and the brown widow Latrodectus geometricus, which, in addition to North America, has a much wider geographic distribution. Elsewhere, others include the European black widow, the Australian redback spider and the closely related New Zealand katipō, several different species in Southern Africa that can be called button spiders, and the South American black-widow spiders. Species vary widely in size. In most cases, the females are dark-coloured and can be readily identified by reddish markings on the central underside (ventral) abdomen, which are often hourglass-shaped.
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Scaffold web spiders or cave cobweb spiders (Nesticidae) are a family of araneomorph spiders closely allied with tangle-web spiders (Theridiidae). Like the Theridiidae, these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. Nesticidae contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus Nesticus is the type for the family and is found throughout the world. The related Eidmannella has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, Eidmannella pallida, is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus Carpathonesticus is found in central Eurasia.
Achaearanea is a genus of comb-footed spiders that was first described by Embrik Strand in 1929.
The spider genus Spintharus occurs from the northeastern United States to Brazil. Nicholas Marcellus Hentz circumscribed the genus in 1850, initially as a monospecific genus containing his newly described species S. flavidus.
Atypus affinis, the purseweb spider, is a mygalomorph spider from Europe and North Africa.
Cryptachaea veruculata is a spider native to Australia and New Zealand. It has been introduced into England and Belgium. The species has potential to control spider mites and leafroller caterpillars in New Zealand.
Cryptachaea is a genus of spiders in the Theridiidae family.
Cryptachaea riparia is a spider species with Palearctic distribution. It is notably found in Lithuania.
Chikunia is a genus of Asian comb-footed spiders that was first described by H. Yoshida in 2009. These spiders are small, often dark or orange colored. This species can be found in solidarity, though they can also be found in colonies.
Phylloneta is a genus of comb-footed spiders formerly considered a sub-genus of Allotheridion, and raised to genus status in 2008. The type species was first described by Eugen von Keyserling in 1884 as Theridion pictipes. As of September 2019 it contains three species and two subspecies with a holarctic distribution: P. impressa, P. pictipes, P. sisyphia, P. s. foliifera, and P. s. torandae.
Nojimaia is a monotypic genus of East Asian comb-footed spiders containing the single species, Nojimaia nipponica. It was first described by H. Yoshida in 2009, and is found in Japan and China.
Stoda is a monotypic genus of African comb-footed spiders containing the single species, Stoda libudum. It was first described by Michael I. Saaristo in 2006, and is found on the Seychelles.
Yaginumena is a genus of comb-footed spiders that was first described by H. Yoshida in 2002. As of June 2020 it contains three species, found in Asia and Turkey: Y. castrata, Y. maculosa, and Y. mutilata.
Yunohamella is a genus of comb-footed spiders that was first described by H. Yoshida in 2007.
