Acariformes

The Acariformes, also known as the Actinotrichida, are the more diverse of the two superorders of mites, alongside Parasitiformes. Over 32,000 described species are found in 351 families, with an estimated total of 440,000 to 929,000 species, including undescribed species.

Oribatida (formerly Cryptostigmata), also known as oribatid mites, moss mites or beetle mites, are an order of mites, in the "chewing Acariformes" clade Sarcoptiformes. They range in size from . There are currently 12,000 species that have been identified, but researchers estimate that there may be anywhere from 60,000 to 120,000 total species. Oribatid mites are by far the most prevalent of all arthropods in forest soils, and are essential for breaking down organic detritus and distributing fungi.

Pyroglyphidae is a family of non-parasitic mites. It includes the house dust mites that live in human dwellings, many species that live in the burrows and nests of other animals, and some pests of dried products stored in humid conditions.

Crotoniidae are a family of mites of the Holosomata group that may be the first animal lineage to have abandoned sexual reproduction and then re-evolved it. This is a spectacular case of atavism, and later convergent evolution.

Brachychthoniidae is a family of oribatids in the order Oribatida. There are about 11 genera and at least 150 described species in Brachychthoniidae.

Sennertia is a genus of mites in the Chaetodactylidae family. There are more than 70 species. Some of these mites are parasites or commensals of bees, but the presence in some bees of specialized structures for carrying mites (acarinarium) indicates the mutualistic nature of the relationship of some species (Sennertia sayutara, Sennertia devincta). Most species of the genus Sennertia settle on adult bees as heteromorphic deutonymphs, but the species Sennertia vaga has no deutonymph and settle on adult bees in the eating adult stages. Reproduction and feeding occurs during resettlement. Most sp
