Amblyomma
Amblyomma is a genus of hard ticks erected by Koch in 1844, whose large, often brightly ornamented species parasitize mammals, birds, and reptiles across the tropics.
Amblyomma americanum
Amblyomma americanum, the lone star tick, is an aggressive human-biting hard tick of the eastern and central United States, identified by the female's white dorsal spot. It vectors ehrlichiosis and tularemia, causes alpha-gal red meat allergy, and does not transmit Lyme disease.
Argas persicus
Argas persicus (fowl tick, poultry tick, blue bug), a soft tick (Argasidae, Oken 1818) parasitizing chickens, ducks, and geese worldwide in warm climates; vector of Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum, distinct from Argas reflexus, the pigeon tick.
Deinocroton
Deinocroton is an extinct Cretaceous tick genus from Burmese amber (~99 Ma), type species D. draculi, likely parasitizing feathered dinosaurs; formerly family Deinocrotonidae, now placed in Nuttalliellidae.
Dermacentor variabilis
Dermacentor variabilis, the American dog tick (formerly Ixodes variabilis), is a North American hard tick, primary US vector of Rocky Mountain spotted fever and tularemia, a three-host tick, not a Lyme vector.
Haemaphysalis
Haemaphysalis (Koch, 1844) is a genus of hard ticks in Ixodidae, the second largest tick genus with about 166-176 species on all continents except Antarctica; includes the invasive Asian longhorned tick H. longicornis.
Ixodes
Ixodes is the largest genus of hard ticks (Ixodidae), with 15 subgenera and roughly 249 to over 280 species, defined by an anterior anal groove, no eyes or festoons, and including the main Lyme disease vectors I. ricinus, I. scapularis, I. pacificus, and I. persulcatus.
Ixodes holocyclus
Ixodes holocyclus, the Australian or eastern paralysis tick, is a hard tick of humid coastal eastern Australia. Its salivary holocyclotoxins cause ascending flaccid paralysis, and it transmits Queensland tick typhus and Q fever.
Ixodes pacificus
Ixodes pacificus, the western blacklegged tick, is a three-year-lifecycle hard tick of far western North America and the primary western US vector of Lyme disease, anaplasmosis, and Borrelia miyamotoi disease.
Ixodes persulcatus
Ixodes persulcatus, the taiga tick, is a Palearctic hard tick of Eurasian forests from 21°N to 66°N; main vector of Siberian and Far Eastern tick-borne encephalitis virus and carrier of 51 microbial agents.
Ixodes ricinus
Ixodes ricinus, the castor bean or sheep tick, is Europe's principal hard-tick disease vector, transmitting Lyme borreliosis and tick-borne encephalitis across a range expanding to higher altitudes and latitudes.
Ixodes scapularis
Ixodes scapularis, the blacklegged or deer tick, is a hard tick of eastern North America and the primary US vector of Lyme disease, anaplasmosis, babesiosis, ehrlichiosis, relapsing fever, and Powassan virus, with a two-year, three-host life cycle.
Ornithodoros moubata
Ornithodoros moubata, the eyeless tampan (Argas moubata, Murray 1877), is an East and southern African soft tick that rapidly feeds on warthogs and humans, vectors Borrelia duttonii relapsing fever and African swine fever virus, and produces the complement inhibitor OmCI.
Rhipicephalus
Rhipicephalus (brown ticks), genus Koch 1844 of hard ticks, ~90 species, African origin; includes brown dog tick R. sanguineus and cattle fever ticks R. (Boophilus) annulatus and microplus, vectors of spotted fevers and bovine babesiosis.
Tick
Ticks (order Ixodida; families Ixodidae and Argasidae) are blood-feeding arachnid ectoparasites with egg, larva, nymph, and adult stages; 1,033 valid species vector Lyme disease, RMSF, and tick-borne encephalitis.
