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 East African Rift, Rift Valley and eastward. It feeds upon a wide variety of species, including livestock, wild mammals, and humans, and can be a vector (epidemiology), vector for various pathogens. The adult male has a distinctive black and ivory ornamentation on its Scute#Insects and other arthropods, scutum. Taxonomy and names ''Rhipicephalus pulchellus'' was species description, 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 ...

Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. 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 axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

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 word obtained by modifying a root word 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, and sometimes to belittle something or someone. A ( abbreviated ) is a word-formation device used to express such meanings. A is a diminutive form with two diminutive suffixes rather than one. Purpose 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. In some contexts, diminutives are also employed in a pejorative sense to denote that someone or something is weak or childish. For example, one of the last Western Roman emperors was Romulus Augustus, but his name was diminutivized to "Romulus Augustulus" to express his powerlessness.

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Specific Epithet (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) 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". Etymology 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 sp ...

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. ''Rhipicephalus'' ticks are commonly called 'the brown tick' as they are mostly brown in colour. Most adult ticks in this genus do not have colour patterns on their scutum (inornate). This makes the species difficult to distinguish from one another because most are quite similar, but 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.

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 plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
