The microscopic mite Lorryia formosa (). The mites are not a defined taxon, but is used for two distinct groups of arachnids, the Acariformes and the Parasitiformes.The phylogeny of the Acari has been relatively little studied, but molecular information from ribosomal DNA is being extensively used to understand relationships between groups.
Hydrachnidia, also known as "water mites", Hydrachnidiae, Hydracarina or Hydrachnellae, are among the most abundant and diverse groups of benthic arthropods, composed of 6,000 described species from 57 families. [3]
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes, [1] following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes. [2] The database was curated from 1997 to June 2013 by Jean P. Euzéby. [3]
Spider mites are members of the family Tetranychidae, which includes about 1,200 species. [1] They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants , where they may spin protective silk webs , and can cause damage by puncturing the plant cells to feed. [ 2 ]
Opilioacarida – a small group of large, long-legged segmented mites. Many species are parasitic (most famous of which are ticks ), but not all. For example, about half of the 10,000 known species in the suborder Mesostigmata are predatory and cryptozoan , living in soil-litter, rotting wood, dung, carrion, nests or house dust.
The oldest fossils of acariform mites are from the Rhynie Chert, Scotland, which dates to the early Devonian, around 410 million years ago [4] [5] The Cretaceous Immensmaris chewbaccei had idiosoma of more than 8 mm (0.31 in) in length and was the largest fossil acariform mite and also the largest erythraeoid mite ever recorded.

Parasitengona is a group of mites, variously ranked as a hyporder [1] or a cohort, [2] between the taxonomic ranks of order and family. They are divided into the aquatic Hydrachnidia (water mites) and the terrestrial Trombidia. [3] The latter includes velvet mites and chiggers. [4]
The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes. [2] The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species. [3]
