Salticidae Genera
Jumping spiders are a group of spiders that constitute the family Salticidae. , this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiderscomprising 13% of spider species. Jumping spiders have some of the best vision among arthropods — being capable of stereoptic color vision — and use sight in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair (the two front middle eyes) being particularly large.

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Plexippus (spider)
''Plexippus'' is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846. It is considered a senior synonym of ''Hissarinus'' and ''Apamamia''. Taxonomy In Maddison's 2015 classification of the family Salticidae, ''Plexippus'' is placed in the tribe Plexippini, part of the Salticoida clade of the subfamily Salticinae. Species it contains forty-two species and one subspecies, found in Oceania, Asia, Europe, Africa, North and South America, Australia, and on the Pacific Islands: *'' Plexippus aper'' Thorell, 1881 – New Guinea *'' Plexippus auberti'' Lessert, 1925 – Kenya, Tanzania *'' Plexippus baro'' Wesolowska & Tomasiewicz, 2008 – Ethiopia *'' Plexippus bhutani'' Zabka, 1990 – Bhutan, China *'' Plexippus brachypus'' Thorell, 1881 – Papua New Guinea (Yule Is.) *'' Plexippus clemens'' ( O.

Philaeus
''Philaeus'' is a genus of jumping spiders that was first described by Tamerlan Thorell in 1869. ''Philaeus maoniuensis'' was moved to genus '' Yllenus'' in 2003. Species it contains seven species with a wide distribution. Most species are from the Mediterranean and West Africa, but single species are known from Guatemala and the Galapagos Islands: *'' Philaeus chrysops'' (Poda, 1761) (type) – Europe, North Africa to Middle East, Turkey, Caucasus, Russia (Europe to Far East), Iran, Central Asia, Afghanistan, China, Mongolia, Korea *'' Philaeus corrugatulus'' Strand, 1917 – Algeria *'' Philaeus daoxianensis'' Peng, Gong & Kim, 2000 – China *'' Philaeus fallax'' (Lucas, 1846) – Algeria *'' Philaeus raribarbis'' Denis, 1955 – Morocco *'' Philaeus ruber'' Peckham & Peckham, 1885 – Guatemala *'' Philaeus steudeli'' Strand, 1906 – West Africa West Africa, also known as Western Africa, is the westernmost region of Africa.

Phidippus
''Phidippus'' is a genus in the family Salticidae (jumping spiders). Some of the largest jumping spiders inhabit this genus, and many species are characterized by their brilliant, iridescent green chelicerae. ''Phidippus'' is distributed almost exclusively in North America, with the exception of two exported species (''Phidippus audax'' and ''Phidippus regius'').Edwards, G. B. (2004). pp. vii, 4–6. , there were about 80 described species in the genus. Species previously described in ''Phidippus'' which are found in India and Bangladesh do not belong in this genus. Name The genus name is likely derived from Cicero's speech ''Pro Rege Deiotaro'' (Speech in Behalf of King Deiotarus): Phidippus was a slave who was physician to King Deiotaros. Literally, the word means "one who spares horses" in Ancient Greek.Ubick ''et al.'' 2005 Species , the World Spider Catalog accepted the following species: * '' Phidippus adonis'' Edwards, 2004 – Mexico * '' Phidippus adumbratus'' Ger ...

Hyllus (spider)
''Hyllus'' is a genus of the spider family Salticidae (jumping spiders). Most species occur in Africa and Madagascar, with many in Australasia and north to India. ''H. insularis'' is found in Greece and Iran, but it is considered misplaced in this genus,Logunov 2001 and is now ''Evarcha insularis''. Description They are medium to large spiders, commonly mistaken by those in the genus ''Evarcha''. They are usually stout, hairy and dully colored. They usually have horns at the top of the Glossary of spider terms, median eyes formed by long bristles. They have a rounded carapace, which is larger than the eye field. Those in the genus ''Evarcha'' are usually smaller and their carapace is thinner. Name Hyllus was the son of Heracles and Deianira in Greek mythology. Species , the World Spider Catalog accepted these species: *''Hyllus acutus'' (John Blackwall, Blackwall, 1877) – Comoro Islands, Seychelles *''Hyllus aegyptiacus'' (Denis, 1947) – Egypt *''Hyllus africanus'' Lesse ...

Deinopidae
Deinopidae, also known as net casting spiders, is a family of cribellate spiders first described by Carl Ludwig Koch in 1850. It consists of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed size, entangling any prey that touch them. The posterior median eyes have excellent night vision, allowing them to cast nets accurately in low-light conditions. These eyes are larger than the others, and sometimes makes these spiders appear to only have two eyes. Ogre-faced spiders ('' Deinopis'') are the best known genus in this family. The name refers to the perceived physical similarity to the mythological creature of the same name. This family also includes the humped-back spiders ('' Menneus''). They are distributed through tropics worldwide from Australia to Africa and the Americas. In Florida, ''Deinopis'' often hangs upside down from a silk line ...

Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the secondary pair of forward appendages among Chelicerata, chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles. From the proximal end (where they are attached to the body) to the distal, they are: the coxa, the Arthropod leg#Trochanter, trochanter, the Arthropod leg#Femur, femur, the short Glossary_of_spider_terms#patella, patella, the Glossary_of_spider_terms#tibia, tibia, and the Arthropod_leg#Tarsus, tarsus. In spiders, the coxae frequently have extensions called Glossary_of_spider_terms#maxilla , maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior arthropod leg, legs. The limbs themselves may be simple tactile organs outwardly resembling the legs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomisidae
The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders. Description Members of this family of spiders do not spin webs, and are ambush predators. The two front legs are usually longer and more robust than the rest of the legs. The back two legs are smaller, and are usually covered in a series of strong spines. They have dull colorations such as brown, grey, or very bright green, pink, white or yellow. They gain their name from the shape of their body, and they usually move sideways or backwards. These spiders are quite easy to identify and can very rarely be confused with Sparassidae family, though the crab spiders are usually smaller. Etymology Spiders in this family are called "crab spiders" due to their resemblance to cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxyopidae
Lynx spiders (Oxyopidae) is a family of araneomorph spiders first described by Tamerlan Thorell in 1870. Most species make little use of webs, instead spending their lives as hunting spiders on plants. Many species frequent flowers in particular, ambushing pollinators, much as crab spiders do. They tend to tolerate members of their own species more than most spiders do, and at least one species has been identified as exhibiting social behaviour. Description There are several genera of Oxyopidae: Oxyopes, Peucetia, Hamataliwa, Hamadruas, Hostus, Pseudohostus, Schaenicoscelis, Tapinillus, and Tapponia. Most spiders in the Oxyopidae family have large spiny bristles on their legs and in many species the bristles form almost a basket-like structure that may assist in confining the prey that they grasp, and protect the spider from its struggles. Most ''Oxyopes'' and ''Hamataliwa'' species are small to medium in size. Lynx spiders, in spite of being largely ambush hunters, are ...

Corinnidae
Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. In 2014, Martín Ramírez recognized the family in a restricted sense, including only the subfamilies Corinninae and Castianeirinae. Two former subfamilies of the Corinnidae are now treated as separate families, Phrurolithidae and Trachelidae. As now recognized, Corinnidae contains 71 genera and over 800 species worldwide. Members of the genus ''Castianeira'' appear to be mimics of ants and velvet ants. Other corinnid ant-like genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
