Inthaeron
''Inthaeron'' is a monotypic genus of Asian araneomorph spiders in the family Cithaeronidae, containing the single species, ''Inthaeron rossi''. It was first described by Norman I. Platnick in 1991, and has only been found in India. Females can be distinguished from those of its sister genus, ''Cithaeron'', by the arrangement of cylindrical gland spigots on the posterior median spinnerets, appearing in two rows rather than in clusters. The name is derived from "India", the country it was first found in, and "Cithaeron", the name of the other genus of ''Cithaeronidae''. Species The only species in the genus is ''Inthaeron rossi''. It was initially found in Mahabaleshwar, Maharashtra, India, though it has also been found in Betul, Madhya Pradesh. Only the female characters were known until 1994, when a male specimen was finally captured and identified, bearing the distinctive, highly coiled embolus. They are generally around long and wide. They have a greenish-brown cephaloth ...

Cithaeronidae
Cithaeronidae is a small family of araneomorph spiders first described by Simon in 1893 Female ''Cithaeron'' are about long, males about . They are pale yellowish, fast-moving spiders that actively hunt at night and rest during the day, building silken retreats below rocks. They prefer very hot, dry stony places. Distribution While ''Inthaeron'' occurs only in India, members of the genus ''Cithaeron'' are found in Africa, India and parts of Eurasia. Three adult females of ''C. praedonius'' were found in Teresina, Piauí, Brazil. As they were found in and near human housings, they presumably were accidentally introduced. This is probably also the case for finds in the Northern Territory of Australia. Another population of ''C. praedonius'' has been discovered in Florida U.S.A., with reports of a stable breeding population.(Pers. comm. Joseph Stiles) Genera and Species This section lists all described species accepted by the World Spider Catalog : ''Cithaeron Cithaeron or K ...

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. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Spider Anatomy
The anatomy of spiders includes many characteristics shared with other arachnids. These characteristics include bodies divided into two tagmata (sections or segments), eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed. Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male spiders have specialized pedipalps that are used to transfer sperm to the female during mating. Many species of spiders exhibit a great deal of sexual dimorphism. External anatomy Spiders, unlike insects, have only two main body parts ( tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) and a ...

Palpal Bulb
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb and ...

Betul, Madhya Pradesh
Betul is a municipality in southern Madhya Pradesh, India. It is the administrative center of Betul district and forms the southernmost part of the Bhopal Division in the Betul (Lok Sabha constituency). Bhimpur village, located west of Betul, is the site of proposed 2800 MW Nuclear Power plant. Name During the early 20th century, Betul was known as Badnur. It derives its present name from its surrounding district, which was named for its former headquarters at Betul Bazar, a small town about to its south. Betul—literally "without" (''be'') "cotton" (''tool'')—was named for its position outside the area's cottonfields. History Nearby Kherla was formerly the seat of an independent kingdom in the medieval and early modern period. Under Company Rule, its fort was permitted to fall into ruin. Badnur became the headquarters of Betul District in 1822. Surrounded by hills on all sides, it was used by the British for the exportation of coal. It supported two bazaars; the ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. 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 anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Spinneret
A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. While most spiders have six spinnerets, some have two, four, or eight. They can move both independently and in concert. Most spinnerets are not simple structures with a single orifice producing a single thread, but complex structures of many microscopic spigots, each producing one filament. This produces the necessary orientation of the protein molecules, without which the silk would be weak and useless. Spigots can be singular or found in groups, which also permits spiders to combine multiple filaments in different ways to produce many kinds of silk for various purposes. Spinneret morphology can help arachnologists identify the taxon of a specimen and the specific morphology of a spigot can determine its use as well ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...
