Pachygnatha is a genus of long-jawed orb-weavers that was first described by Carl Jakob Sundevall in 1823. [2]
As of March 2021 [update] it contains forty-two species and two subspecies: [1]
In synonymy:
Neriene is a genus of sheet weavers that was first described by John Blackwall in 1833.
Enoplognatha is a genus of comb-footed spiders that was first described by P. Pavesi in 1880. They have both a large colulus and a subspherical abdomen. Males usually have enlarged chelicerae. It is considered a senior synonym of Symopagia.
Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and it contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them. The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning "jaw". Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands. One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.
Parasteatoda is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. The name is a combination of the Ancient Greek "para-" (παρά), meaning "near" or "next to", and the theridiid genus Steatoda. The Japanese name for this genus is O-himogumo zoku.
Walckenaeria is a genus of dwarf spiders that was first described by John Blackwall in 1833. It is a senior synonym of Paragonatium, as well as Wideria, Cornicularia, Prosopotheca, Tigellinus, and Trachynella.
Dictyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Carl Jakob Sundevall in 1833.
Lepthyphantes is a genus of dwarf spiders that was first described by Anton Menge in 1866.
Hahnia is a genus of dwarf sheet spiders that was first described by C. L. Koch in 1841.
