Tasmanicosa is a genus of spiders in the family Lycosidae. It was first described in 1959 by Roewer. As of 2017 [update] , it contains 14 species, all from Australia. [1]
Tasmanicosa comprises the following species: [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.
Ant spiders are members of the family Zodariidae. They are small to medium-sized eight-eyed spiders found in all tropical and subtropical regions of South America, Africa, Madagascar, Australia-New Guinea, New Zealand, Arabia and the Indian subcontinent. Most species are daytime hunters and live together with ants, mimicking their behavior and sometimes even their chemical traits. Although little is known about most zodariids, members of the genus Zodarion apparently feed only on ants; a number of other genera in the family are apparently also ant specialists.
The spider genus Aname is endemic to Australia, with one species found only on Tasmania. It contains the black wishbone spider, A. atra.
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.
Artoriopsis is a genus of wolf spiders first described by Volker W. Framenau in 2007. They are endemic to Australia and are most diverse in the southern half of the continent, though A. anacardium is found in the tropical north of Australia. Their body size ranges from 3 to 11 mm, with males smaller than females. They appear to prefer open, vegetated or sandy areas of moderate humidity.
Trochosa is a large wolf spider genus found worldwide.
Artoria is a genus of spiders in the family Lycosidae. It was first described in 1877 by Thorell. As of 2017, it contains 32 species.
Dingosa is a genus of spiders in the family Lycosidae. It was first described in 1955 by Roewer. As of 2017, it contains 6 species from Australia and from South America.
Geolycosa is a genus of wolf spiders first described in 1904.
Hoggicosa is a genus of wolf spiders first described by Carl Friedrich Roewer in 1960. The name is a reference to arachnologist Henry Roughton Hogg.
Kangarosa is a genus of spiders in the family Lycosidae. It was first described in 2010 by Framenau. As of 2017, it contains 10 species from Australia.
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.
Venatrix is a genus of wolf spiders first described by Carl Friedrich Roewer in 1960.
Venonia is a genus of spiders in the family Lycosidae. It was first described in 1894 by Thorell. As of 2017, it contains 16 species.
Barbara Baehr is a research scientist, entomologist, arachnologist, and spider taxonomist. She has described over 400 new spider species, mostly from Australia. She is originally from Pforzheim, Germany.
Tasmanicosa godeffroyi, one of the wolf spiders, is a mid sized spider found in all states of Australia. Perhaps the most commonly noticed of the wolf spiders in Australia. Variable in pattern and colour, though the underside of the abdomen is black. Wolf spiders tend to rest at the entrance of their burrows, and their eyes reflect the light of passing cars or torchlight. The burrow has a thin veil of silk, without a lid, unlike some other wolf spiders. The burrow is circular in cross section, it travels down for around 15 cm, then parallel with the ground for the next 15 cm. The body length of the female is up to 27 mm, the male 25 mm.
Venatrix furcillata, one of the wolf spiders, is a mid sized spider found in eastern Australia. The body length of the female is up to 13 mm, the male 9 mm. The abdomen has distinctive tapering markings. Sometimes noted in suburban gardens and lawns. It lives in a simple burrow, but may be seen migrating in large numbers to a communal web, an unusual feature for wolf spiders. The grey coloured spherical egg sac is around 6 mm in diameter, carried by the female. Eggs are 45 to 60 in number, 0.8 mm in diameter. Prey is ground dwelling insects. The spider has been identified as occurring in Queensland, New South Wales, and Victoria.
