Agelenidae Genera
The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus ''Agelenopsis''. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (''Eratigena agrestis'') may be medically significant, and some evidence suggests it might cause necrotic lesions, but the matter remains subject to debate. The most widely accepted common name for members of the family is funnel weaver. Description The body length of the smallest Agelenidae spiders are about , excluding the legs, while the larger species grow to long. Some exceptionally large species, such as '' Eratigena atrica'', may reach in total leg span. Agelenids have eight eyes in two horizontal rows of four. Their cephalothoraces narrow somewhat towards the front where the eyes are. Their abdomens are more or less oval, usually patterned with two rows of lines and spots. Some species have longitudinal lines on the dorsal surface of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eratigena Agrestis
''Eratigena'' is a genus of spider in the family Agelenidae. Most of its species were moved from the genus '' Tegenaria'' in 2013, of which the genus name is an anagram. Two species that frequently build webs in and around human dwellings are now placed in this genus: the Agressive House Spider (''Eratigena agrestis'') (known as the hobo spider in the United States), native to Europe and Central Asia and introduced to North America, and the giant house spider (''Eratigena atrica''), native to Europe and also introduced into North America. Description They are medium to large spiders. Two symmetrical dark bands are present dorsally on the carapace, which can be serrated or reduced, usually to three or four conspicuous triangles. They also have plumose hairs on the carapace, legs, and opisthosoma. Their rows of eyes are only slightly curved in either direction. Taxonomy Phylogeny Species now placed in the genus ''Eratigena'' were previously placed in '' Tegenaria'' and '' Malthon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trophallaxis
Trophallaxis () is the transfer of food or other fluids among members of a community through mouth-to-mouth (stomodeum, stomodeal) or anus-to-mouth (proctodeum, proctodeal) feeding. Along with nutrients, trophallaxis can involve the transfer of molecules such as pheromones, organisms such as Symbiosis, symbionts, and information to serve as a form of communication. Trophallaxis is used by some birds, gray wolf, gray wolves, vampire bats, and is most highly developed in eusocial insects such as ants, wasps, bees, and termites. Etymology Tropho- (prefix or suffix) is derived from the Greek trophé, meaning 'nourishment'. The Greek 'allaxis' means 'exchange'. The word was introduced by the entomologist William Morton Wheeler in 1918. Evolutionary significance Trophallaxis was used in the past to support theories on the origin of sociality in insects. The Swiss psychologist and entomologist Auguste Forel also believed that food sharing was key to ant society and he used an illust ...

Allagelena
''Allagelena'' is a genus of Asian funnel weavers first described by Z. S. Zhang, Ming-Sheng Zhu & D. X. Song in 2006. Taxonomy The genus was created in 2006, initially for four Chinese species previously placed in '' Agelena''. The name ''Allagelena'' is derived from ''allo-'', different, and the genus name ''Agelena'', so meaning "different from ''Agelena''", specifically in male and female sexual characters. Three further species were later transferred to this genus. Species it contains nine species: *'' Allagelena bifida'' (Wang, 1997) – China *'' Allagelena bistriata'' (Grube, 1861) (type Type may refer to: Science and technology Computing * Typing, producing text via a keyboard, typewriter, etc. * Data type, collection of values used for computations. * File type * TYPE (DOS command), a command to display contents of a file. * ...) – Russia (Far East), China *'' Allagelena difficilis'' (Fox, 1936) – China, Korea *'' Allagelena donggukensis'' (Kim, 1996) – K ...

Acutipetala
''Acutipetala'' is a small genus of southeast Asian funnel weavers native to the evergreen forests of northern Thailand. They are medium-sized spiders, to long, and are distinguished by the distinctive appearance of several genital structures, including the embolus and the median apophysis of the male pedipalp. The eyes are in two rows, both of which are strongly curved forward. The genus was first described by P. Dankittipakul and Z. S.
