Wolf spiders are members of the family Lycosidae, from the Ancient Greek word "λύκος" meaning "wolf". They are robust and agile hunters with excellent eyesight. They live mostly in solitude and hunt alone, and do not spin webs. Some are opportunistic hunters pouncing upon prey as they find it or even chasing it over short distances. Some wait for passing prey in or near the mouth of a burrow.
Wandering spiders (Ctenidae) are a family of spiders that includes the Brazilian wandering spiders. These spiders have a distinctive longitudinal groove on the top-rear of their oval carapace similar to those of the Amaurobiidae. They are highly defensive and venomous nocturnal hunters. Despite their notoriety for being dangerous, only a few members of Phoneutria have venom known to be hazardous to humans, but the venoms of this family are poorly known, so all larger ctenids should be treated with caution.
Amaurobius is a genus of tangled nest spiders that was first described by Carl Ludwig Koch in 1837.
Pireneitega is a genus of funnel weavers first described by Kyukichi Kishida in 1955.
Sibirocosa is a genus of wolf spiders containing seven species, all from Russia, mostly found from northeastern Siberia south to Primorsky Krai. Spiders of this genus are dark coloured and hairy with a body length of 5.25 - 7.25 mm.
Tibioploides is a genus of sheet weavers that was first described by K. Y. Eskov & Y. M. Marusik in 1991.
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.
Gnaphosa is a genus of ground spiders that was first described by Pierre André Latreille in 1804. They all have a serrated keel on the retromargin of each chelicera.

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.
Diphya is a genus of long-jawed orb-weavers that was first described by H. Nicolet in 1849. D. tanasevitchi and D. albulum were transferred from Lophomma in 2007.

Psammitis is a genus of crab spiders first described by Anton Menge in 1876.
