Leiurus Nasheri
''Leiurus'' is a genus of scorpion of the family Buthidae. The most common species, ''L. quinquestriatus'', is also known under the common name Deathstalker. It is distributed widely across North Africa and the Middle East, including the western and southern Arabian Peninsula and southeastern Turkey. At least one species occurs in West Africa (northern Cameroon). Taxonomy The genus was introduced in 1828 by C.G. Ehrenberg (in Hemprich & Ehrenberg 1828), originally as a subgenus of the genus ''Androctonus''. It was finally elevated to genus rank by M. Vachon in 1949. The genus was long considered to be monotypic, containing a single species, ''L. quinquestriatus'', but research since 2002 has shown that there are indeed several species. Diversity Currently five species are recognized within this genus, but their validity is under discussion. F. Kovařík (2007) suspected that ''L. jordanensis'' and ''L. savanicola'' are possible synonyms of ''L. quinquestriatus''. *' ...

Christian Gottfried Ehrenberg
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. Ehrenberg was an evangelist and was considered to be of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile valley and the northern coasts of the Red Sea, where he made a special study of the corals. Subsequently, parts of Syria, Arabia and Abyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chelae
A chela ()also called a claw, nipper, or pinceris a pincer-like organ at the end of certain limbs of some arthropods. The name comes from Ancient Greek , through New Latin '. The plural form is chelae. Legs bearing a chela are called chelipeds. Another name is ''claw'' because most chelae are curved and have a sharp point like a claw. Chelae can be present at the tips of arthropod legs as well as their pedipalps. Chelae are distinct from spider chelicerae in that they do not contain venomous glands and cannot distribute venom. See also * Pincer (biology) * Pincer (tool) Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an ... References Arthropod anatomy {{Arthropod-anatomy-stub ...

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] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Leiurus Quinquestriatus
The deathstalker (''Leiurus quinquestriatus'') is a species of scorpion, a member of the family Buthidae. It is also known as the Palestine yellow scorpion, Omdurman scorpion, Naqab desert scorpion and by many other colloquial names, which generally originate from the commercial captive trade of the animal. To eliminate confusion, especially important with potentially dangerous species, the scientific name is normally used to refer to them. The name ''Leiurus quinquestriatus'' roughly translates into English as "five-striped smooth-tail". In 2014, the subspecies ''L. q. hebraeus'' was separated from it and elevated to its own species ''Leiurus hebraeus''. Other species of the genus '' Leiurus'' are also often referred to as "deathstalkers". ''Leiurus quinquestriatus'' is yellow, and long, with an average of . Geographic range ''Leiurus quinquestriatus'' can be found in desert and scrubland habitats ranging from North Africa through to the Middle East. Its range covers a wide ...

Leiurus Abdullahbayrami
''Leiurus abdullahbayrami'' is a species of scorpion in the family Buthidae. Its venom is highly toxic to humans, but can be used in medical development. Taxonomy ''Leiurus abdullahbayram'' was originally considered conspecific with the deathstalker (''L. quinquestriatus''), but was reclassified in 2009 based on mitochondrial DNA analyses. Description ''Leiurus abdullahbayrami'' has a brown cephalothorax, yellow legs, head, and tail. One of the very end segments of the tail is brown instead of yellow. In scientific terms, the background color of the prosoma, mesosoma, and segment V of metasoma is black and the appendages of the Leiurus Abdullahbayrami are yellowish. The centrolateral and posteriomedian carinae (at the end of the pinchers) are fused together and lyre-shaped is formed. It has fixed fingers with 11 oblique granule rows. It has movable fingers of pedipalps with 4 distal and 11 oblique granule rows. The ventrolateral carinae of metasomal segment V have la ...
