Rhipicephalus Pulchellus
The zebra tick or yellow back tick (''Rhipicephalus pulchellus'') is a species of hard tick. It is common in the Horn of Africa, with a habitat of the Rift Valley and eastward. It feeds upon a wide variety of species, including livestock, wild mammals, and humans, and can be a vector for various pathogens. The adult male has a distinctive black and ivory ornamentation on its scutum. Taxonomy and names ''Rhipicephalus pulchellus'' was described by Carl Eduard Adolph Gerstaecker, who initially placed it in the genus ''Dermacentor'' due to the ornamentation; all ''Dermacentor'' ticks are ornate. Its syntypes are at the Museum für Naturkunde. transferred this species to ''Rhipicephalus'' in 1897. R. I. Pocock described a junior synonym, ''R. marmoreus'', in 1900; its holotype was deposited at the Natural History Museum, London. By 1901, Neumann had synonymized it with ''R. pulchellus''. In 1926, Maria Tonelli-Rondelli described a subspecies ''R. p. humeralis'', but in 1949, F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (anatomy)
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 ...

Maria Tonelli-Rondelli
Maria Tonelli-Rondelli (1899 – 1970) was an Italian entomologist who studied the taxonomy and identification of ticks (Ixodidae), especially South American species. Early life and education She was born in Turin in 1899, the daughter of Alipio Rondelli and Maria Pia (Marina) Zanetti. She studied at University of Turin, graduating in natural sciences in 1921 and then geography in 1923. After graduating she worked at the university. She married the mathematician Leonida Tonelli in 1927. He died in 1946. Career She began her career by translating into Italian volumes of ''Zoology'' by Rémy Perrier. This was published with a preface by the Italian zoologist Umberto Pierantoni. However the focus of her career was on ticks. She examined specimens in the collections at Milan and Turin museums and specimens from scientific expeditions. In 1928 she described a new species, ''Ixodes nivalis'' from specimens obtained in the Gran Paradiso National Park in Italy. She worked especially ...

Diminutive
A diminutive is a root word that has been modified to convey a slighter degree of its root meaning, either to convey the smallness of the object or quality named, or to convey a sense of intimacy or endearment. A (abbreviated ) is a word-formation device used to express such meanings. In many languages, such forms can be translated as "little" and diminutives can also be formed as multi-word constructions such as " Tiny Tim". Diminutives are often employed as nicknames and pet names when speaking to small children and when expressing extreme tenderness and intimacy to an adult. The opposite of the diminutive form is the augmentative. Beyond the ''diminutive form'' of a single word, a ''diminutive'' can be a multi-word name, such as "Tiny Tim" or "Little Dorrit". In many languages, formation of diminutives by adding suffixes is a productive part of the language. For example, in Spanish can be a nickname for someone who is overweight, and by adding an suffix, it becomes which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Specific Epithet (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Rhipicephalus Maculatus
''Rhipicephalus'' is a genus of ticks in the family Ixodidae, the hard ticks, consisting of about 74 or 75 species. Most are native to tropical Africa.Olwoch, J. M., et al. (2007)Climate change and the genus ''Rhipicephalus'' (Acari: Ixodidae) in Africa.''Onderstepoort J Vet Res'' 74(1), 45-72. Species are difficult to distinguish from one another because most are quite similar, while individuals of one particular species can be quite variable.Beati, L. and J. E. Keirans. (2001)Analysis of the systematic relationships among ticks of the genera ''Rhipicephalus'' and ''Boophilus'' (Acari: Ixodidae) based on mitochondrial 12S ribosomal DNA gene sequences and morphological characters.''The Journal of Parasitology'' 87(1), 32. Most of the characteristics used to identify species pertain to male and immature specimens, and "females are sometimes simply impossible to identify". Many ''Rhipicephalus'' spp. are of economic, medical, and veterinary importance because they are vectors of pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
