Frontinella is a genus of dwarf spiders that was first described by Frederick Octavius Pickard-Cambridge in 1902. [2]
As of May 2019 [update] it contains nine species and one subspecies, found in China, El Salvador, Mexico, and the United States: [1]
Linyphiidae is a family of very small spiders comprising 4667 described species in 618 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly known; new genera and species are still being discovered throughout the world. The newest such genus is Yuelushannus from China, formally described in May 2020. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Florinda, commonly called black-tailed red sheetweaver or red grass spider, is a monotypic genus of dwarf spiders containing the single species, Florinda coccinea. It was first described by Octavius Pickard-Cambridge in 1896, and has only been found in Mexico, the West Indies, and the United States. It is common in the southeastern United States, inhabiting grasslands, lawns, and agricultural fields.
Phanias is a genus of jumping spiders that was first described by Frederick Octavius Pickard-Cambridge in 1901. They are similar to members of Marpissa, but have three pairs of spines beneath the first tibia.
Sidusa is a genus of jumping spiders that was first described by George and Elizabeth Peckham in 1895.
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.
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.
Mallos is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by O. Pickard-Cambridge in 1902. Among the genus, Mallos gregalis is known to be a social spider species, living in groups and signaling each other by vibrating their web.
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.
Erigone is a genus of dwarf spiders that was first described by Jean Victoire Audouin in 1826. They are carnivorous, preying on small insects such as psylla and flies. One of the distinctive characters for this genus is the presence of teeth bordering the carapace.
Melpomene is a genus of funnel weavers first described by O. Pickard-Cambridge in 1898. They range from southwestern U.S. to Panama and can grow up to 7 to 8.5 millimetres long. Roth and Brame noted that, with many undescribed species, the genus appears to be a catchall or "wastebasket taxon" for several unrelated species that may represent several genera.
Linyphia is a genus of dwarf spiders that was first described by Pierre André Latreille in 1804. The name is Greek, and means "thread-weaver" or "linen maker".
Novalena is a genus of North American and Caribbean funnel weavers first described by R. V. Chamberlin & Wilton Ivie in 1942.
Elaver is a genus of sac spiders first described by Octavius Pickard-Cambridge in 1898.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
Hamataliwa is a genus of lynx spiders that was first described by Eugen von Keyserling in 1887.
Ixchela is a genus of cellar spiders that was first described by B. A. Huber in 2000.
Hentziectypus is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. Originally placed with Theridion, it was moved to Achaearanea in 1955, and to its own genus in 2008. These spiders most resemble members of Cryptachaea, but are distinguished by a median apophysis that is broadly attached to the tegulum. Spiders of Parasteatoda have a median apophysis attached to the embolus, while those of Achaearanea have a hooked paracymbium on the pedipalps of males.
Neospintharus is a genus of comb-footed spiders that was first described by H. Exline in 1950. It was synonymized with Argyrodes in 1962, but revalidated in 2004.
