Acanthophorus
''Acanthophorus'' is a genus of prionine longhorn beetles from the Indian subcontinent. It is monotypic, being represented by the single species ''Acanthophorus serraticornis''. Other species that were formerly included in the genus are now placed in other genera. Growing to nearly long, they are among the largest beetles of India. These beetles are reddish to brownish. The mandibles In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone ... vary in size with some males having much larger mandibles than the females. These bear two to three strong teeth from midway to the tip. The antennae are twelve segmented with the fifth to the eleventh having a spiny outgrowth at the tip.

Prioninae
The Prioninae are a subfamily of Cerambycidae (long-horned beetles). They are typically large (25–70 mm) and usually brown or black. The males of a few genera sport large mandibles that are used in fights with other males, similar to stag beetles. These beetles are commonly nocturnal and are attracted to light. The majority of the Prioninae whose biology is known are borers whose larvae feed on rotting wood or roots. Genera The following genera are recognised in the subfamily Prioninae: * '' Acalodegma'' * '' Acanthinodera'' * '' Acanthophorus'' * '' Acideres'' * '' Aegolipton'' * '' Aegosoma'' * '' Aerogrammus'' * ''Aesa'' * '' Afraustraloderes'' * '' Agrianome'' * '' Allaiocerus'' * '' Allomallodon'' * '' Anacolus'' * '' Analophus'' * '' Ancistrotus'' * '' Andinotrichoderes'' * '' Anoeme'' * '' Anomophysis'' * '' Anomotoma'' * '' Anoplotoma'' * '' Anthracocentrus'' * '' Aplagiognathus'' * '' Apocaulus'' * '' Apterocaulus'' * '' Arba'' * '' Archetypus'' * '' Archodontes' ...

Guillaume-Antoine Olivier
Guillaume-Antoine Olivier (; 19 January 1756, Les Arcs near Toulon – 1 October 1814, Lyon) was a French entomologist and naturalist. Life Olivier studied medicine in Montpellier, where he became good friends with Pierre Marie Auguste Broussonet. With Jean Guillaume Bruguière and Jean-Baptiste Lamarck, he collaborated in the creation of ''Journal d'Histoire Naturelle'' (1792). Afterwards, he served as a naturalist on a 6-year scientific journey that took him to Asia Minor, Persia, Egypt, Cyprus and Corfu. He returned to France in 1798 with a large collection of natural history specimens from his travels. Later, he was associated with the ''École nationale vétérinaire d'Alfort'', where in 1811, he was appointed professor of zoology. Olivier was a close friend of Johan Christian Fabricius and a patron of Pierre André Latreille. Although primarily an entomologist, Olivier also worked in the scientific field of herpetology, describing several new species of Asian lizards. ...

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 ...

Longhorn Beetle
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short (e.g., '' Neandra brunnea'') and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns. Description Other than the typical long antennal length, the most consistently distinctive feature of the family is that the antennal sockets are located on low tubercles on the face; other beetles with long antennae lack these tubercles, and cerambycids with short antennae still possess them. They otherwise vary greatly in size, shap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Subcontinent
The Indian subcontinent is a list of the physiographic regions of the world, physiographical region in United Nations geoscheme for Asia#Southern Asia, Southern Asia. It is situated on the Indian Plate, projecting southwards into the Indian Ocean from the Himalayas. Geopolitically, it includes the countries of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka."Indian subcontinent". ''Oxford Dictionary of English, New Oxford Dictionary of English'' () New York: Oxford University Press, 2001; p. 929: "the part of Asia south of the Himalayas which forms a peninsula extending into the Indian Ocean, between the Arabian Sea and the Bay of Bengal. Historically forming the whole territory of Greater India, the region is now divided into three countries named Bangladesh, India and Pakistan." The terms ''Indian subcontinent'' and ''South Asia'' are often used interchangeably to denote the region, although the geopolitical term of South Asia frequently includes Afghanist ...

Monotypic
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. ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

Mandible (insect Mouthpart)
Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals. Insect mandibles, which appear to be evolutionarily derived from legs, move in the horizontal plane unlike those of vertebrates, which appear to be derived from gill arches and move vertically. Grasshoppers, crickets, and other simple insects The mouthparts of orthopteran insects are often used as a basic example of mandibulate (chewing) mouthparts, and the mandibles themselves are likewise generalized in structure. They are large and hardened, shaped like pinchers, with cutting surfaces on the distal portion and chewing or grinding surfaces basally. They are usually lined with teeth and move sideways. Large pieces of leaves can therefore be cut and then pulverized near the mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
