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 ...

Ornithodoros
''Ornithodoros'' is a genus in the soft-bodied tick family, Argasidae. Physiology The opening between the midgut and hindgut has been lost, making the ticks unable to pass digestive waste products out of their bodies. Taxonomy The Linnean name derives from ''ornithos'' ( gr, ὄρνιθος) and ''doros'' ( gr, Δωρόν), meaning "bird" and "gift", respectively. It contains these species: *'' Ornithodoros alactagalis'' Issaakjan, 1936 *†''Ornithodoros antiquus'' Poinar, 1995 *''Ornithodoros apertus'' Walton, 1962 *''Ornithodoros arenicolous'' Hoogstraal, 1953 *''Ornithodoros asperus'' Warburton, 1918 *''Ornithodoros atacamensis'' Muñoz-Leal, Venzal & González-Acuña, 2016 *'' Ornithodoros brasiliensis'' Aragão, 1923 *''Ornithodoros cholodkovskyi'' Pavlovsky, 1930 *''Ornithodoros compactus'' Walton, 1962 *''Ornithodoros coniceps'' Canestrini, 1890 *''Ornithodoros costalis'' Diatta, Bouattour, Durand, Renaud & Trape, 2013 *''Ornithodoros coriaceus'' Koch, 1844 *''Ornith ...

Ixodidae
The Ixodidae are the family of hard ticks or scale ticks, one of the three families of ticks, consisting of over 700 species. They are known as 'hard ticks' because they have a scutum or hard shield, which the other major family of ticks, the 'soft ticks' (Argasidae), lack. They are ectoparasites of a wide range of host species, and some are vectors of pathogens that can cause human disease. Description They are distinguished from the Argasidae by the presence of a scutum. In both the nymph and the adult, a prominent gnathosoma (or capitulum, mouth and feeding parts) projects forward from the animal's body; in the Argasidae, conversely, the gnathosoma is concealed beneath the body. They differ, too, in their lifecycle; Ixodidae that attach to a host bite painlessly and are generally unnoticed, and they remain in place until they engorge and are ready to change their skin; this process may take days or weeks. Some species drop off the host to moult in a safe place, whereas others r ...

Ticks Of Domestic Animals
Ticks of domestic animals directly cause poor health and loss of production to their hosts. Ticks also transmit numerous kinds of viruses, bacteria, and protozoa between domestic animals. These microbes cause diseases which can be severely debilitating or fatal to domestic animals, and may also affect humans. Ticks are especially important to domestic animals in tropical and subtropical countries, where the warm climate enables many species to flourish. Also, the large populations of wild animals in warm countries provide a reservoir of ticks and infective microbes that spread to domestic animals. Farmers of livestock animals use many methods to control ticks, and related treatments are used to reduce infestation of companion animals. Variety of ticks affecting domestic animals Ticks are invertebrate animals in the phylum Arthropoda, and are related to spiders. Ticks are in the subclass Acari, which consists of many orders of mites and one tick order, the Ixodida. Some mites are ...

Otobius
''Otobius'' is a genus in the soft-bodied tick family, Argasidae.

Otobius Megnini
''Otobius megnini'', also known as the spinose ear tick, is a soft-bodied tick that is only parasitic in the larval and nymphal stages. As its common name suggests, the spinose ear tick's parasitic forms are usually found within the ears of the definitive host. This tick has a worldwide distribution, with common hosts that include horses, cattle, sheep, goats, and dogs. Importance Spinose ear ticks are a constant source of annoyance and irritation for their definitive hosts. Their tendency to occur in large numbers can cause ulceration of the inner ear, high sensitivity of the ears, large amounts of blood loss, and even deafness. Heavily infested animals often shake and rub their heads, which can cause their outer ears to become excoriated and raw. Several cases of human infestation have been reported, and the tick has been incriminated in some instances of pathogen transmission. Anatomy As with many soft ticks, the mouthparts of ''O. megnini'' are not visible from the dorsa ...

Carl Ludwig Koch
Carl Ludwig Koch (21 September 1778 – 23 August 1857) was a German entomologist and arachnologist. He was responsible for classifying a great number of spiders, including the Brazilian whiteknee tarantula and common house spider. He was born in Kusel, Germany, and died in Nuremberg, Germany. Carl Ludwig Koch was an inspector of water and forests. His principal work ''Die Arachniden'' (1831–1848) (16 volumes) was commenced by Carl Wilhelm Hahn (1786–1836). Koch was responsible for the last 12 volumes. He also finished the chapter on spiders in ''Faunae insectorum germanicae initia oder Deutschlands Insecten'' lements of the insect fauna of Germanya work by Georg Wolfgang Franz Panzer (1755–1829). He also co-authored, with Georg Karl Berendt, an important monograph ''Die im Bernstein befindlichen Myriapoden, Arachniden und Apteren der Vorwelt'' (1854) on arachnids, myriapods, and wingless insects in amber based on material in Berendt's collection, now held in the Muse ...
