C. Linnaeus, 1758 - animals
- Subkingdom: Bilateria
(Hatschek, 1888) Cavalier-Smith, 1983 - bilaterians
- Branch: Protostomia
Grobben, 1908 - protostomes
- Infrakingdom: Ecdysozoa
A.M.A. Aguinaldo et al., 1997 ex T. Cavalier-Smith, 1998 - ecdysozoans
- Superphylum: Panarthropoda
Cuvier
- Phylum: Arthropoda
Latreille, 1829 - Arthropods
- Subphylum: Arachnomorpha

C. Linnaeus, 1758 - animals
The Subclass Acari is further organized into finer groupings including:
- Order (7): Actinedida · Astigmata · Holothyrida · Ixodida · Mesostigmata · Opilioacarida · Oribatida
Orders
Actinedida
The Acariformes are the more diverse of the two superorders of mites. There are over 32,000 described species in 351 families, and an estimated total of 440,000 to 929,000, including undescribed species. [more]
Astigmata
The Astigmatina are a "cohort" of mites. They belong to the Sarcoptiformes, which contain the "biting" Acariformes. Many species are parasites of vertebrates. Most notorious among these are the Psoroptidia, which contain such notable taxa as feather mites and Sarcoptes scabiei. [more]
Holothyrida
Ixodida
Ticks are small arachnids in the order Ixodida. Along with mites, they constitute the subclass Acarina. Ticks are ectoparasites (external parasites), living by hematophagy on the blood of mammals, birds, and sometimes reptiles and amphibians. By consuming on the blood they can get larger and then to a size to where you can see them better, and once they've gotten big enough they eventually move on to another host. Ticks are vectors of a number of diseases, including Lyme disease, Q fever (rare; more commonly transmitted by infected excreta), Colorado tick fever, Rocky Mountain Spotted Fever, tularemia, tick-borne relapsing fever, babesiosis, ehrlichiosis, Tick paralysis and tick-borne meningoencephalitis, as well as bovine anaplasmosis.

Mesostigmata
Mesostigmata is an order of mites belonging to the Parasitiformes. Unlike most members of that group, many of these mites are not parasitic but free-living and predatory. They can be recognized by the single pair of spiracles positioned laterally on the body. [more]
Opilioacarida
Oribatida
Oribatida (formerly Cryptostigmata), also known as moss mites or beetle mites, are an order of mites, in the "chewing Acariformes" clade Sarcoptiformes. They range in size from 0.2 to 1.4 millimetres (0.008 to 0.055 in). [more]
At least 1,807 species and subspecies belong to the Order Oribatida.
