Macrargus is a genus of dwarf spiders that was first described by Friedrich Dahl in 1886. [3]
As of May 2021 [update] it contains five species: [1]
The Thomisidae are a family of spiders, including about 175 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders.
Linyphiidae is a family of very small spiders comprising 4694 described species in 623 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 Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Pseudeuophrys is a genus of jumping spiders that was first described by Friedrich Dahl in 1912. The name is a combination of the Ancient Greek "pseudo-" (ψευδής), meaning "false", and the salticid genus Euophrys. It was briefly synonymized with Euophrys, but this decision was later reversed.
Agroeca is a genus of liocranid sac spiders that was first described by Niklas Westring in 1861.
Acartauchenius is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1884.
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".
Tengella is a genus of false wolf spiders that was first described by Friedrich Dahl in 1901. It is a senior synonym of Metafecenia.
Robertus is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1879. It is considered a senior synonym of Garritus.
