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.

Tetralycosa is a genus of Australian spiders in the family Lycosidae first described by Roewer in 1960, later revised by Framenau & Hudson to include thirteen species. Genetic studies show that these spiders all diverged from a common ancestor who likely wandered into the salty area and remained. They live exclusively in certain saline environments of Australia's interior, including coastal beaches, mound springs, clay pans, and salt lakes. There haven't been enough studies to establish a conservation status, but some species have only been found in solitary salt lakes, suggesting that the increase of mining, agriculture, recreational, and similar disturbances of these unique ecosystems may eventually lead to their extinction if not properly regulated.
Vesubia is a genus of spiders in the family Lycosidae. It was first described in 1910 by Simon. As of 2017, it contains 3 species.
