Allocosa dufouri is a wolf spider (family Lycosidae) found in Portugal and Spain. [1]
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.
Nursery web spiders (Pisauridae) is a family of araneomorph spiders first described by Eugène Simon in 1890. They resemble wolf spiders (Lycosidae) except for several key differences. Wolf spiders have two very prominent eyes in addition to the other six, while a nursery web spider's eyes are all about the same size. Additionally, female nursery web spiders carry their egg sacs with their jaws and pedipalps instead of attaching them to their spinnerets as wolf spiders do. When the eggs are about to hatch, a female spider builds a nursery "tent", places her egg sac inside, and stands guard outside, hence the family's common name. Like the wolf spiders, however, the nursery web spiders are roaming hunters that don't use webs for catching prey. They have a wide variety of prey, and larger species may prey upon vertebrates, particularly amphibians and fish.
Tord Tamerlan Teodor Thorell was a Swedish arachnologist.
Lycosa tarantula is the species originally known as the tarantula, a name that nowadays commonly refers to spiders in another family entirely, the Theraphosidae. It now may be better called the tarantula wolf spider, being in the wolf spider family, the Lycosidae. L. tarantula is a large species found in southern Europe, especially in the Apulia region of Italy and near the city of Taranto, from which it gets its name.
Nukuhiva is a genus of spiders with a single species, Nukuhiva adamsoni, that occurs only on the Marquesas Islands in French Polynesia. It is in the wolf spider family, Lycosidae. It has been found on Nuku Hiva and on Ua Huka, a smaller island about 25 km (16 mi) to the east.
Sexual cannibalism is when a female cannibalizes her mate prior to, or after copulation. It is a trait observed in many arachnid orders and several insect orders. Several hypotheses to explain this seemingly paradoxical behavior have been proposed. The adaptive foraging hypothesis, aggressive spillover hypothesis and mistaken identity hypothesis are among the proposed hypotheses to explain how sexual cannibalism evolved. This behavior is believed to have evolved as a manifestation of sexual conflict, occurring when the reproductive interests of males and females differ. In many species that exhibit sexual cannibalism, the female consumes the male upon detection. Females of cannibalistic species are generally hostile and unwilling to mate; thus many males of these species have developed adaptive behaviors to counteract female aggression.
The Artoriinae are a subfamily of wolf spiders. The monophyly of the subfamily has been confirmed in a molecular phylogenetic study, although the relationships among the subfamilies was shown to be less certain.
Allocosa brasiliensis is a burrowing wolf spider species from southern South America. Long known to science, it remained almost unstudied until its unusual sexual behavior was described in the early 21st century.
Allocosa is a spider genus of the wolf spider family, Lycosidae. The 130 or more recognized species are spread worldwide.

Hesperocosa is a genus of spiders in the family Lycosidae. It was first described in 1937 by Gertsch & Wallace. As of 2017, it contains only one species, Hesperocosa unica, found in the United States.
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.
