Portia Fimbriata
''Portia fimbriata'', sometimes called the fringed jumping spider, is a jumping spider (family Salticidae) found in Australia and Southeast Asia. Adult females have bodies 6.8 to 10.5 millimetres long, while those of adult males are 5.2 to 6.5 millimetres long. Both sexes have a generally dark brown carapace, reddish brown chelicerae ("fangs"), a brown underside, dark brown palps with white hairs, and dark brown abdomens with white spots on the upper side. Both sexes have fine, faint markings and soft fringes of hair, and the legs are spindly and fringed. However, specimens from New Guinea and Indonesia have orange-brown carapaces and yellowish abdomens. In all species of the genus '' Portia'', the abdomen distends when the spider is well fed or producing eggs. The hunting tactics of ''Portia'' are versatile and adaptable. All members of ''Portia'' have instinctive hunting tactics for their most common prey, but can improvise by trial and error against unfamiliar prey ...

Carl Ludwig Doleschall
Carl Ludwig Doleschall ( hu, Doleschall Lajos; sk, Karol Ľudovít Doležal; born 15 July 1827 – died 26 February 1859) was born in Vág-Újhely, Kingdom of Hungary, Austrian Empire (now Nové Mesto nad Váhom, Slovakia), as the son of the theologian Michael Doleschall, and died in Ambon Island, Moluccas, Dutch East Indies (today in Indonesia) only 31 years old. His name is sometimes also written as "Doleschal". He studied medicine at the University of Vienna and became a military surgeon for the Dutch army, stationed in Java in 1853. He studied invertebrates and plants extensively, and described many arachnids and insects, notably diptera. In 1852, he published the work ''Systematisches Verzeichniß der im Kaiserthum Österreich vorkommenden Spinnen''. He spent the last half of his life mostly in the island of Ambon. He was visited by the British naturalist Alfred Russel Wallace in 1857. Shortly after Wallace left, he died of consumption on 26 February 1859. After his death hi ...

Cephalothorax
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind. (The terms ''prosoma'' and ''opisthosoma'' are equivalent to ''cephalothorax'' and ''abdomen'' in some groups.) The word ''cephalothorax'' is derived from the Greek words for head (, ') and thorax (, '). This fusion of the head and thorax is seen in chelicerates and crustaceans; in other groups, such as the Hexapoda (including insects), the head remains free of the thorax. In horseshoe crabs and many crustaceans, a hard shell called the carapace covers the cephalothorax.

Mantis
Mantises are an order (Mantodea) of insects that contains over 2,400 species in about 460 genera in 33 families. The largest family is the Mantidae ("mantids"). Mantises are distributed worldwide in temperate and tropical habitats. They have triangular heads with bulging eyes supported on flexible necks. Their elongated bodies may or may not have wings, but all Mantodea have forelegs that are greatly enlarged and adapted for catching and gripping prey; their upright posture, while remaining stationary with forearms folded, has led to the common name praying mantis. The closest relatives of mantises are termites and cockroaches (Blattodea), which are all within the superorder Dictyoptera. Mantises are sometimes confused with stick insects ( Phasmatodea), other elongated insects such as grasshoppers (Orthoptera), or other more distantly related insects with raptorial forelegs such as mantisflies (Mantispidae). Mantises are mostly ambush predators, but a few ground-dwelling s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Jumping Spiders
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 p ...

Lyssomaninae
Lyssomaninae is a subfamily of jumping spiders. It includes four genera, three from the New World. Description Members of the subfamily Lyssomaninae are mostly green or yellow, and have long legs compared to other salticids. The anterior lateral eyes form a second row behind the anterior median eyes. The male palpal bulb has a membraneous conductor. Taxonomy The subfamily Lyssomaninae, as described in 1976 by María Elena Galiano and in 1980 by Wanless, was agreed by both authors not to be monophyletic, and to consist of three groups. It was formally divided into three subfamilies, Onomastinae, Asemoneinae and Lyssomaninae ''s.s.'', by Wayne Maddison in 2015. He included only two genera, '' Chinoscopus'' and '' Lyssomanes'', although noting that ''Lyssomanes'' might be paraphyletic. Molecular data strongly supported the monophyly of the group defined in this way. In 2016, Maddison described a new genus, ''Sumakuru'', which he placed in Lyssomaninae. Maddison originally kept t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salticinae
Salticinae is a subfamily of jumping spiders (family Salticidae). It includes over 90% of the known species of jumping spiders. The subfamily is divided into two unranked clades: Amycoida and Salticoida. Description Members of the subfamily Salticinae have a number of features in common that distinguish them from the remaining salticids. Females lack a tarsal claw on the pedipalp. The palpal bulb of male basal salticids has a distinctive median apophysis, which is absent in the subfamily, and the cymbium is constricted at the tibial joint. Members also have a more complex tracheal system, which may be connected with their movements, which are more abrupt than other salticids, giving them a recognizable gait. Taxonomy Phylogeny The relationships among the basal salticids are not yet fully resolved; summary cladograms published in both 2014 and 2015 show unresolved branching for five basal subfamilies. However, Hisponinae is resolved as sister to Salticinae, which is the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Spartaeinae
The Spartaeinae are a subfamily of the spider family Salticidae (jumping spiders). The subfamily was established by Fred R. Wanless in 1984 to include the groups Boetheae, Cocaleae, Lineae, Codeteae and Cyrbeae, which in turn were defined by Eugène Simon. The Spartaeinae are palaeotropical, with an exceptional diversity in the Malaysian and Indonesian archipelagos. They are unusual salticids that are considered basal to the phylogenetic tree of jumping spiders. Like the Lyssomaninae they lack many derived features that the Salticinae possess. Spartaeinae usually have large posterior median eyes. However, these were reduced in the genera ''Cyrba'', ''Gelotia'' and ''Wanlessia''. Genera In 2015, Spartaeinae was divided into three tribes with 29 genera. One has been added since. Tribe Cocalodini * '' Allococalodes'' Wanless, 1982 * '' Cocalodes'' Pocock, 1897 * '' Cucudeta'' Maddison, 2009 * '' Depreissia'' Lessert, 1942 * '' Tabuina'' Maddison, 2009 * '' Yamangalea'' Madd ...
