Achaearanea
''Achaearanea'' is a genus of comb-footed spiders that was first described by Embrik Strand in 1929. It used to include the extremely abundant common house spider, which was transferred to genus '' Parasteatoda'' in 2006, together with many other species. '' A. veruculata'' and many more species were moved to genus '' Cryptachaea'' in 2008. Others were moved to the revived '' Henziectypus''. The genus was thus reduced from about 150 species to about 22 species during major revisions. Possibly even more species should be transferred to other genera. Description This genus includes small and large theridiids. The legs are medium long, with spines and usually many hairs. Their web is an irregular network of threads, usually in a sheltered place. Distribution Species are found around the world, with several species from South America, China and Korea, India, Australia and Africa. Some species are endemic to several small islands. Species it contains twenty-eight species, found i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Common House Spider
''Parasteatoda tepidariorum'', the common house spider or American house spider, is a spider species of the genus '' Parasteatoda'' with a cosmopolitan distribution. Common house spiders are synanthropic and live in and near human dwellings. Their prey mechanism is similar to that of the other cobweb spiders: the spider follows disturbances transmitted along the web to entangle and then paralyze its prey, which usually consists of household insects and other invertebrates (often considered as pests). Description Appearance Common house spiders are variable in color from tan to nearly black, frequently with patterns of differing shades on their body. Females are generally between long, and males are generally between long. They can be an inch (2.5 cm) or more across with legs outspread. ''P. tepidariorum'' is similar in body shape to widow spiders. Males have a less bulbous abdomen than females. Common house spiders' size and coloration allow the spiders to blend into the ...

Theridiidae
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of Araneomorphae, araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genus, genera, and is the most common arthropod found in human dwellings throughout the world. Theridiid spiders are both Entelegynae, entelegyne, meaning that the females have a genital plate, and Cribellum, ecribellate, meaning that they spin sticky capture silk instead of woolly silk. They have a comb of serrated bristles (setae) on the Arthropod leg, tarsus of the fourth leg. The family includes some model organisms for research, including the List of medically significant spider bites, medically important Latrodectus, widow spiders. They are important to studies characterizing their venom and its clinical manifestation, but widow spiders are also used in research on spider silk and sexual biology, including ...

Parasteatoda
''Parasteatoda'' is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946.

Description ''Parasteatoda'' species have a characteristic teardrop-shaped abdomen, with the anterior section much higher than the carapace and the spinnerets pointed downwards. The abdomen's colouration is highly variable, both between and often within species. They have slight sexual dimorphism; males are visually similar to females, although slightly smaller. Species It is mostly an Old World genus, with many species found in Asia and New Guinea, though the distribution reaches into Europe. A few species originate from the New World, but many have been introduced, and they are becoming more widespread in the Americas and Europe. it contains forty-two species ...
