Helophora is a genus of dwarf spiders that was first described by Anton Menge in 1866. [2]
As of May 2019 [update] it contains five species, found in China, Russia, 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.
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.
Drapetisca is a genus of dwarf spiders that was first described by Anton Menge in 1866. Females are 4 to 5 millimetres long, and males are 3 to 4 millimetres long. They are common on tree trunks from July to September, and they feed on insects and smaller spiders.
Ceratinella is a genus of dwarf spiders that was first described by James Henry Emerton in 1882. They are very similar to both Ceraticelus and Idionella, and the taxonomy of these spiders may change.
Agroeca is a genus of liocranid sac spiders that was first described by Niklas Westring in 1861.
Cicurina, also called the cave meshweaver, is a genus of dwarf sheet spiders that was first described by Anton Menge in 1871. Originally placed with the funnel weavers, it was moved to the Dictynidae in 1967, then to the Hahniidae in 2017. The name is from the Latin root "cucur-", meaning "to tame".
Dictyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Carl Jakob Sundevall in 1833.
Euryopis is a genus of comb-footed spiders that was first described by Anton Menge in 1868.
Lasaeola is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1881. The type species was described under the name Pachydactylus pronus, but was renamed Lasaeola prona when it was discovered that the name "Pachydactylus" was preoccupied. Both this genus and Deliana were removed from the synonymy of Dipoena in 1988, but many of these species require more study before their placement is certain.
Lepthyphantes is a genus of dwarf spiders that was first described by Anton Menge in 1866.
Bathyphantes is a genus of dwarf spiders that was first described by Anton Menge in 1866.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Lathys is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1884. It is a replacement name for "Lethia" Menge, 1869 because that name was already in use as a synonym for a genus of moths.
Drassyllus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922.
Haplodrassus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922. They range from 3 to 10 millimetres. H. signifer is the most widespread species, found across North America except for Alaska and northern Canada.
Sosticus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922.
Incestophantes is a genus of dwarf spiders that was first described by A. V. Tanasevitch in 1992.
Microneta is a genus of dwarf spiders that was first described by Anton Menge in 1869.
Stemonyphantes is a genus of sheet weavers that was first described by Anton Menge in 1866.
