|Genus:|| Tigrosa |
Tigrosa is a genus of spiders in the family Lycosidae, found in North America.
The genus Tigrosa was erected by Allen R. Brady in 2012. Prior to 1990, many medium to large wolf spiders (family Lycosidae) from North America were placed in the genus Lycosa . In 1990 it was accepted that Lycosa was a Mediterranean genus and did not occur in North America; seven species were transferred to Hogna . A more detailed examination of the type species of Hogna, Hogna radiata , convinced Brady that a new genus was needed for some of the North American species that had been moved to Hogna. Characters that distinguish Tigrosa from Hogna include the pattern on the upper (dorsal) surface of the cephalothorax, the arrangement of the eyes, and the shape of the female epigyne.
The generic name Tigrosa is intended to mean "fierce like a tiger", referring to the patterning and behaviour of Tigrosa species.
As of May 2016 [update] , the World Spider Catalog accepted the following species:
Wolf spiders are members of the family Lycosidae. They are robust and agile hunters with excellent eyesight. They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow.
Tigrosa aspersa is a large wolf spider that inhabits the eastern United States. Compared to its close relative Tigrosa helluo, T. aspersa is much larger. This species was known as Hogna aspersa prior to 2012, when it was moved to Tigrosa.
Lycosa tarantula is the species originally known as the tarantula, a name that nowadays in English 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.
Maevia is a spider genus of the family Salticidae.
Lycosa is a genus of wolf spiders distributed throughout most of the world. Sometimes called the "true tarantula", though not closely related to the spiders most commonly called tarantulas today, Lycosa spp. can be distinguished from common wolf spiders by their relatively large size. This genus includes the European Lycosa tarantula, which was once associated with tarantism, a dubious affliction whose symptoms included shaking, cold sweats, and a high fever, asserted to be curable only by the traditional tarantella dance. No scientific substantiation of that myth is known; the venom of Lycosa spiders is generally not harmful.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Hogna ericeticola, known as the rosemary wolf spider, is a species of spider in the family Lycosidae. It is endemic to Florida, in the United States.
→Hogna carolinensis, commonly known as the Carolina wolf spider, is found across North America. It is the largest of the wolf spiders in North America, typically measuring at 18–20 mm for males and 22–35 mm for females.
Rabidosa is a genus of spiders described by Roewer (1960). The family is Lycosidae. It contains the following species:
Tigrosa helluo is a species of spider belonging to the family Lycosidae, also known as wolf spiders. T. helluo was formerly known as Hogna helluo before differences between dorsal color patterns, habitat preferences, body structures, etc. were discovered. The species is native to the United States, Canada, and Mexico. It can be found across the eastern half of the United States, primarily in the Northeast and New England, and as far west as Nebraska and Kansas. T. helluo can be found in diverse habitats including woods, marshes, fields, and riparian areas. Typically, members of this species prefer to live in wetter areas as opposed to dry environments. Males tend to live for around a year and females will live for close to two years.
Gladicosa is a genus of wolf spiders found in the United States and Canada.
Lycosa indagatrix is a species of spiders of the genus Lycosa native to India and Sri Lanka. The species is about 22 mm long. The habitats include tunnels and burrows and it is a purely nocturnal spider.
Hogna baltimoriana is a species of wolf spider in the family Lycosidae. It is found in the USA and Canada.
Hogna thetis is an endemic spider species of the family Lycosidae that lives on Príncipe in São Tomé and Príncipe. It was first described as Lycosa thetis in 1907 by Eugène Simon.
Tigrosa annexa is a species of wolf spider (Lycosidae) native to eastern North America from Texas, east to Florida, and north to Ohio.
Tigrosa georgicola is a species of wolf spider in the family Lycosidae. It is endemic to the Southeastern United States. The type specimen was collected in Burke County, Georgia. Its habitat includes the forest floor of deciduous woodlands.
Hogna pseudoceratiola is a species of wolf spider in the genus Hogna of the family Lycosidae. It was described for the first time by Wallace in 1942.
Karakumosa is a genus of Asian wolf spiders first described by Dmitri V. Logunov and A. V. Ponomarev in 2020.
Serratacosa is a genus of wolf spiders. It was first described by L. Y. Wang, X. J. Peng and Z. S. Zhang in 2021, and it has only been found in China. As of January 2022 it contains only three species: S. himalayensis, S. medogensis, and S. multidontata.
