Argas Walkerae
''Argas walkerae'' Kaiser & Hoogstraal, 1969, as its common name "fowl tampan" reflects, is a soft-bodied argasid tick primarily parasitizing chickens and other domestic fowl. In South Africa its natural range spans the eastern region of Eastern Cape Province from the warmer coastal regions on the Indian Ocean in the south to the cooler mountainous Drakensberg range in the northeast of the Province, with local distribution more strongly associated with the presence of fowls and wooden fowl houses, than climate alone. The specific epithet honors the scientific contributions of Dr. Jane Brotherton Walker Jane Brotherton Walker (31 January 1925 – 3 April 2009) was a leading 20th century expert in the field of tick taxonomy, particularly in Africa.Ivan G.

Harry Hoogstraal
Harry Hoogstraal (born in Chicago, Illinois, February 24, 1917, died in Cairo, Egypt, on his 69th birthday, February 24, 1986) was an American entomologist and parasitologist. He was described as "the greatest authority on ticks and tickborne diseases who ever lived." The American Society of Tropical Medicine and Hygiene's ''Harry Hoogstraal Medal for Outstanding Achievement in Medical Entomology'' honors his contributions to science. Life and work Hoogstraal earned B.A. and M.S. degrees (1938 and 1942) from the University of Illinois at Chicago, before his training was interrupted by World War II to serve as an officer entomologist (1943–1946) in the United States Army. He later received Ph.D. (1959) and D.Sc. (1971) degrees from the London School of Hygiene and Tropical Medicine. As a master's degree candidate at the University of Illinois, he organized and led (1938–1941) four multi-disciplinary biological expeditions into the mountain and desert portions of western and s ...

Argasidae
The Argasidae are the family of soft ticks, one of the three families of ticks. The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. The currently accepted genera are '' Antricola'', '' Argas'', '' Nothoaspis'', ''Ornithodoros'', and '' Otobius''. The Argasidae are very common in South Asia, along with 96 other species of ticks, making South Asia the region with the highest biodiversity of ticks worldwide. Soft ticks are resistant to desiccation and can live for several years in arid conditions. Physical characteristics Soft ticks lack the hard scutum present in the hard ticks (Ixodidae). The gnathosoma (or capitulum, the mouthparts-bearing structure) is located on the underside of the animal's body and is not readily visible, while in the Ixodidae, the gnathosoma projects forward from the body. The lateral edges of the body are rounded. See also *Ticks of domestic animals Ticks of ...

Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In addit ...

Chickens
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature. Genetic studies have pointed to mult ...

Fowl
Fowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes). Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae (initially termed Galloanseri) (Latin ''gallus'' (“rooster”) + ''ānser'' (“goose”)). This clade is also supported by morphological and DNA sequence data as well as retrotransposon presence/absence data. Terminology As opposed to "fowl", "poultry" is a term for any kind of domesticated bird or bird captive-raised for meat, eggs, or feathers; ostriches, for example, are sometimes kept as poultry, but are neither gamefowl nor waterfowl. In colloquial speech, however, the term "fowl" is often used near-synonymously with "poultry," and many languages do not distinguish between "poultry" and "fowl". Nonetheless, the fact that the Galliformes and Anseriformes most ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ...

Eastern Cape Province
The Eastern Cape is one of the provinces of South Africa. Its capital is Bhisho, but its two largest cities are East London and Gqeberha. The second largest province in the country (at 168,966 km2) after Northern Cape, it was formed in 1994 out of the Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area which was known as the Xhosa Kingdom began to be settled by Europeans who originally came from England and some from Scotland and Ireland. Since South Africa's early years, many Xhosas believed in Africanism and figures such as Walter Rubusana believed that the rights of Xhosa people and Africans in general, could not be protected unless Africans mobilized and worked together. As a result, the Eastern Cape is home to many anti-apartheid leaders such as Robert Sobukwe, Oliver Tambo, Nelson Mandela, Wal ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ...

Drakensberg
The Drakensberg (Afrikaans: Drakensberge, Zulu: uKhahlambha, Sotho: Maluti) is the eastern portion of the Great Escarpment, which encloses the central Southern African plateau. The Great Escarpment reaches its greatest elevation – within the border region of South Africa and Lesotho. The Drakensberg escarpment stretches for more than from the Eastern Cape Province in the South, then successively forms, in order from south to north, the border between Lesotho and the Eastern Cape and the border between Lesotho and KwaZulu-Natal Province. Thereafter it forms the border between KwaZulu-Natal and the Free State, and next as the border between KwaZulu-Natal and Mpumalanga Province. The escarpment winds north from there, through Mpumalanga, where it includes features such as the Blyde River Canyon, Three Rondavels, and God's Window. It then extends farther north to Hoedspruit in southeastern Limpopo where it is known as 'Klein Drakensberg' by the Afrikaner. From Hoedspruit i ...

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 ...
