Maevia Gracilipes
''Maevia'' is a spider genus of the family Salticidae (jumping spiders). Maevia appears to have been a large blanket genus in its beginnings, with not closely related species from the New World and the region from India to the Moluccas being lumped there. As the type species is from North America, those that occur in the New World were left in the genus, with most others transferred to other genera. However, several species exist in Asia for which there has been no information since their description, often more than a hundred years ago, so transferring them to other genera proves difficult.Murphy & Murphy 2000: 270 Species * ''Maevia albozonata'' Hasselt, 1882 – Sumatra * ''Maevia expansa'' Barnes, 1955 – United States * '' Maevia gracilipes'' Taczanowski, 1878 – Peru * ''Maevia inclemens'' ( Walckenaer, 1837) – USA, Canada * ''Maevia intermedia'' Barnes, 1955 – USA * ''Maevia quadrilineata'' Hasselt, 1882 – Sumatra * ''Maevia susiformis'' Taczanowski, 1878 – Per ...

Maevia Inclemens
''Maevia inclemens'' or the dimorphic jumping spider is a relatively common and colorful jumping spider of North America. In the males there are polymorphism (biology), two forms, a very rare phenomenon in zoology. These use different courtship, courting displays, and differ in appearance: the "tufted" morph (zoology), morph has a black body and pedipalps ("palps"), three black tufts across its "head", and pale legs; and the "gray" morph has black and white stripes all over its body and legs, orange palps, and no tufts. However, each form accounts for 50% of the adult males, and they are equally successful in mating. A female of ''Maevia inclemens'' is long, while males are long. Like all jumping spiders, ''M. inclemens'' has excellent vision. The main eyes, in the front-and-center position, are large, and are more acute than those of a cat and about 10 times as acute as a dragonfly's. The remaining three pairs of eyes are along the sides of the head, and work as motion detecto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Of North America
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate ...

Salticidae Genera
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it 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 being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye pa ...

Menemerus
''Menemerus'' is a genus of jumping spiders that was first described by Eugène Louis Simon in 1868. They are long, flattened in shape, and very hairy, usually with brown and grayish hairs. Most species have white edges on the thorax. The abdomen is often oval, or sometimes elongated or rounded. Species it contains sixty-seven species, found worldwide in warmer climates. *'' M. affinis'' Wesolowska & van Harten, 2010 – United Arab Emirates *'' M. albocinctus'' Keyserling, 1890 – India (Nicobar Is.) *'' M. animatus'' O.

Metacyrba
''Metacyrba'' is a genus of jumping spiders that was first described by Frederick Octavius Pickard-Cambridge in 1901. The name is combined from Ancient Greek "after, beside" and the salticid genus ''Cyrba''. Species it contains seven species and one subspecies, found in South America, Mexico, the United States, Cuba, and on the Greater Antilles: *'' Metacyrba alberti'' Cala-Riquelme, 2017 – Cuba *'' Metacyrba floridana'' Gertsch, 1934 – USA *'' Metacyrba insularis'' (Banks, 1902) – Ecuador (Galapagos Is.) *'' Metacyrba pictipes'' Banks, 1903 – Hispaniola *'' Metacyrba punctata'' (Peckham & Peckham, 1894) – USA to Ecuador *'' Metacyrba taeniola'' (Hentz, 1846) ( type) – USA, Mexico **'' Metacyrba t. similis'' Banks, 1904 – USA, Mexico *'' Metacyrba venusta'' (Chickering Chickering may refer to: * Chickering, Suffolk, a place in Suffolk, England * Chickering & Sons, the piano company that was created by Jonas Chickering * Arthur M.

Marpissa
''Marpissa'' is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846. The name is derived from Marpissa, an ancient Greek village.

Maevia Trilineata
''Maevia'' is a spider genus of the family Salticidae (jumping spiders). Maevia appears to have been a large blanket genus in its beginnings, with not closely related species from the New World and the region from India to the Moluccas being lumped there. As the type species is from North America, those that occur in the New World were left in the genus, with most others transferred to other genera. However, several species exist in Asia for which there has been no information since their description, often more than a hundred years ago, so transferring them to other genera proves difficult.Murphy & Murphy 2000: 270 Species * '' Maevia albozonata'' Hasselt, 1882 – Sumatra * '' Maevia expansa'' Barnes, 1955 – United States * '' Maevia gracilipes'' Taczanowski, 1878 – Peru * ''Maevia inclemens'' (Walckenaer, 1837) – USA, Canada * '' Maevia intermedia'' Barnes, 1955 – USA * '' Maevia quadrilineata'' Hasselt, 1882 – Sumatra * '' Maevia susiformis'' Taczanowski, 1878 – P ...

Maevia Intermedia
''Maevia intermedia'' is one of eight species of Jumping spider, Salticidae, or jumping spider, in the genus ''Maevia'', and is native to North America.Barnes, Robert D. (August 12, 1955). "North American Jumping Spiders of the Genus ''Maevia''". ''American Museum Novitates''. The American Museum of Natural History (1746): 1–13. Retrieved 1 Nov 2023 This species was originally reported by American Zoologist Robert D. Barnes in 1955 as a needed distinguishment between the similar-looking ''Maevia'' species, especially those found in the Americas. ''Maevia intermedia'' are extremely similar in Morphology (biology), morphology and overall ecology to their taxonomical order's more studied Model organism, model species ''Maevia inclemens''. ''M. inclemens'' is a dimorphic spider that possesses two color Polymorphism (biology), morphs in males of its species.
