Maevia
''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 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] |
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''.

Moluccas
The Maluku Islands (; Indonesian: ''Kepulauan Maluku'') or the Moluccas () are an archipelago in the east of Indonesia. Tectonically they are located on the Halmahera Plate within the Molucca Sea Collision Zone. Geographically they are located east of Sulawesi, west of New Guinea, and north and east of Timor. Lying within Wallacea (mostly east of the biogeographical Weber Line), the Maluku Islands have been considered as a geographical and cultural intersection of Asia and Oceania. The islands were known as the Spice Islands because of the nutmeg, mace and cloves that were exclusively found there, the presence of which sparked colonial interest from Europe in the sixteenth century. The Maluku Islands formed a single province from Indonesian independence until 1999, when it was split into two provinces. A new province, North Maluku, incorporates the area between Morotai and Sula, with the arc of islands from Buru and Seram to Wetar remaining within the existing Maluku Province. ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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 ...
