Rhondes Sarasini
''Rhondes sarasini'' is an endemic species of jumping spider in the genus ''Rhondes'' that lives in New Caledonia. First described in 2016 by Barbara Patoleta, only the female has yet to be identified. The holotype was discovered by Jean Roux and Karl Friedrich Sarasin in 1911, and the species name commemorates the latter. It is a small and slender spider, with a wide light brown cephalothorax that is typically long and a thinner abdomen, typically long, that has a pattern of light and dark patches. It differs from other members of the genus in its design of the epigyne, which has a wide pocket and short copulatory openings. Taxonomy ''Rhondes sarasini'' was first identified in 2016 by Barbara Patoleta. The female holotype had been collected in 1911 by Jean Roux and Karl Friedrich Sarasin, and it is the latter that is commemorated in the species name. The genus ''Rhondes'' was raised in 1901 by Eugène Simon for endemic species of jumping spiders in New Caledonia. It has been ...

Spiders Of New Caledonia
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), 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 Family (biology), families have been recorded by Taxonomy (biology), 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 segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical Gl ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grande Terre (New Caledonia)
Grande Terre is the largest and principal island of New Caledonia, which is a territory of France. History British explorer James Cook sighted Grande Terre in 1774 and named it "New Caledonia", Caledonia being the Latin name for what is now Scotland. The island's mountains reminded him of Scotland. Eventually, the name "New Caledonia" became applied to Grande Terre and its surrounding islands. It was annexed by the French Empire and became a penal colony in 1853. Today, Grande Terre has about 268,000 residents. Geography The largest settlement on Grande Terre is Nouméa, the capital city of New Caledonia. Locals refer to Grand Terre as "Le Caillou", the pebble. The island has a fairly hot and humid climate, though varying as the south-east trade winds bring relatively cool air. Surrounding the island and especially to the north-west is the New Caledonian barrier reef. The island is located roughly east of Australia. Grande Terre is oriented northwest-to-southeast; its area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhondes Flexibilis
''Rhondes flexibilis'' is an endemic species of jumping spider in the genus ''Rhondes'' that lives in New Caledonia. First described in 2016 by Barbara Patoleta, the species is common across the island, living in rainforests. It is small and slender, with a wide brown hairy cephalothorax and thinner abdomen that has a pattern of light and dark patches. The male, which is slightly larger, has a variably-shaped sclerite on the palpal bulb, after which the species is named. The female has a slightly less distinctive abdominal pattern and an epigyne with a relatively long and narrow pocket. Taxonomy ''Rhondes flexibilis'' was first identified in 2016 by Barbara Patoleta. The species was named after shape of the sclerite on the palpal bulb, which is quite variable. The genus ''Rhondes'' was raised in 1901 by Eugène Simon for endemic species of jumping spiders in New Caledonia. It has been placed in the tribe Viciriini in the clade Astioida. Genetic analysis confirms that it is re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhondes Atypicus
''Rhondes atypicus'' is an endemic species of jumping spider in the genus '' Rhondes'' that lives in New Caledonia. First described in 2016 by Barbara Patoleta, the species has been found on both Grande Terre and Isle of Pines, living in rainforests. It is small and slender, with a wide brown hairy cephalothorax and thinner abdomen. The abdominal markings differ between the male and female, which gives rise to the species name. The male light and dark patches on its abdomen, and has a longer and thicker embolus than other species in the genus. The female, which is larger, has a striped abdominal pattern, which distinguishes the species from the similar '' Rhondes flexibilis''. Taxonomy ''Rhondes atypicus'' was first identified in 2016 by Barbara Patoleta. The species was named after the way that the patterns on the abdomen differs between the male and the female. The genus '' Rhondes'' was raised in 1901 by Eugène Simon for endemic species of jumping spiders in New Caledoni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of 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: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids. At present, the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clypeus (arthropod Anatomy)
The clypeus is one of the sclerites that make up the face of an arthropod. In insects, the clypeus delimits the lower margin of the face, with the labrum articulated along the ventral margin of the clypeus. The mandibles bracket the labrum, but do not touch the clypeus. The dorsal margin of the clypeus is below the antennal sockets. The clypeus is often well-defined by sulci ("grooves") along its lateral and dorsal margins, and is most commonly rectangular or trapezoidal in overall shape. The post-clypeus is a large nose-like structure that lies between the eyes and makes up much of the front of the head in cicadas. In spiders, the clypeus is generally the area between the anterior edge of the carapace A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises.

Chelicerae
The chelicerae () are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly to pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain (or are connected to) venom glands, and are used to inject venom into prey or a perceived threat. In ''Pisaurina mira'', also known as the nursery web spider, the chelicerae are utilized to snatch the prey once it becomes within reach, facilitating the "sit-and-wait ambush predator" behavior. Both pseudoscorpions and harvestmen have structures on their chelicerae that are used for grooming (papillae in pseudoscorpions, cheliceral teeth in Opiliones). Types Chelicerae can be divided into three kinds: jackknife chelicerae, scissor chelicerae, and 3-segmented chelate chelicerae. Jackknife chelicerae The jackknife chelicera is subchelate (with ...
