Nanoa is a sister genus of Pimoa , in the spider family Pimoidae, containing the single species Nanoa enana.
Combined from Greek nanos "dwarf" and the ending -oa, which follows the other pimoid genera Pimoa and Weintrauboa . The name enana of the only species means "dwarf" in Spanish.
N. enana is the smallest known pimoid species, with a total body length of only 1.5 mm.
N. enana occurs in northern California and southern Oregon.
Cybaeidae is a family of spiders first described by Nathan Banks in 1892. The diving bell spider or water spider Argyroneta aquatica was previously included in this family, but is now in the family Dictynidae.
Spider taxonomy is that part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida with about 46,000 described species. However, there are likely many species that have escaped the human eye to this day, and many specimens stored in collections waiting to be described and classified. It is estimated that only one third to one half of the total number of existing species have been described.
Pimoidae is a small family of araneomorph spiders first described by J. Wunderlich in 1986. It contains 37 species in four genera and is monophyletic. It is closely related to the Linyphiidae, and is sometimes treated as synonymous with that family.
Pimoa is a genus of spiders in the family Pimoidae. Its sister genus is Nanoa.
Austrochilidae is a small spider family with ten species in three genera. Austrochilus and Thaida are endemic to the Andean forest of central and southern Chile and adjacent Argentina, while Hickmania is endemic to Tasmania. The monophyly of the family and the relationships among the genera are uncertain as of May 2017.
Araneoidea is a taxon of araneomorph spiders, termed "araneoids", treated as a superfamily. As with many such groups, its circumscription has varied; in particular some families that had at one time moved to the Palpimanoidea have more recently been restored to Araneoidea. A 2014 treatment includes 18 families, with the araneoids making up about 26% of the total number of known spider species; a 2016 treatment includes essentially the same taxa, but now divided into 17 families.
The Entelegynae or entelegynes are a subgroup of araneomorph spiders, the largest of the two main groups into which the araneomorphs were traditionally divided. Females have a genital plate (epigynum) and a "flow through" fertilization system; males have complex palpal bulbs. Molecular phylogenetic studies have supported the monophyly of Entelegynae.
Sinopimoa is a monotypic genus of Chinese sheet weavers containing the single species, Sinopimoa bicolor. It was first described by S. Q. Li & J. Wunderlich in 2008, and is found in China. It was originally placed in its own family (Sinopimoidae) but is now considered a member of the Linyphiidae, and it may be a member of the Erigoninae.
Pimoa cthulhu is a species of the spider family Pimoidae. It is one of twenty-one described species in the genus Pimoa.
Laetesia is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1908.
Pimoa rupicola is a species of the spiders family Pimoidae found in France and Italy. First described in 1884, it is one of twenty-eight described species in the genus Pimoa.
Exechocentrus is a genus of Madagascan orb-weaver spiders first described by Eugène Simon in 1889. It is a bolas-using spider, capturing its prey with one or more sticky drops at the end of a single line of silk rather than in a web.
Erigonops is a monotypic genus of African dwarf spiders containing the single species, Erigonops littoralis. It was first described by N. Scharff in 1990, and has only been found in South Africa.
Microctenonyx is a genus of dwarf spiders that was first described by Friedrich Dahl in 1886.
Pecado is a monotypic genus of dwarf spiders containing the single species, Pecado impudicus. It was first described by G. Hormiga & N. Scharff in 2005, and has only been found in Spain, Morocco, and Algeria.
Camafroneta is a genus of dwarf spiders containing the single species, Camafroneta oku. It was first described by H. Frick & N. Scharff in 2018, and is only found in Cameroon.
Cyrtarachninae is a subfamily of spiders in the family Araneidae. The group has been circumscribed in several different ways. It originated as the group Cyrtarachneae, described by Eugène Simon in 1892. The group was later treated at different ranks: as a tribe, both under Simon's name and as Cyrtarachnini, and as the subfamily Cyrtarachninae. Circumscriptions have varied. The broadest circumscription, Cyrtarachninae sensu lato (s.l.), includes three of Simon's original groups, including the bolas spiders. Unlike most araneids, members of the subfamily do not construct orb webs, some not using webs at all to capture prey, some using one or more sticky drops on a single line, while others construct webs with few widely spaced non-spiral threads, some triangular. Many have been shown to attract prey by producing analogues of insect sex pheromones, particularly to attract male moths. Adult females may mimic snails, bird droppings and other objects, and so are able to remain exposed during the day time, capturing prey at night.
Exechocentrus lancearius is a species of spider in the orb-weaver spider family Araneidae, found only in Madagascar. It was initially described from a partial specimen of an adult female. The first description of a complete specimen and its prey-catching behaviour was published in 2012. E. lancearius is a bolas spider. Rather than using a web, adult females catch their prey by using a line with one or two sticky drops which they swing.
