Arctacaridae
Arctacaridae is a small family of mites in the order Mesostigmata, discovered and described by Evans in 1955 from arctic regions of North America. The family contains two genera, Arctacarus and Proarctacarus, with six recognized species total. These mites are among the few mesostigmatid lineages specifically adapted to cold, high-latitude environments. The genus Proarctacarus was established in 2003 based on specimens from Canada and the northwestern United States.
Cheiroseius
Cheiroseius is a genus of predatory mites in the family Blattisociidae (formerly placed in Ascidae), representing the second largest genus in this family. The genus contains approximately 80 described species distributed across multiple continents. Species have been documented from wet habitats including leaf litter and aquatic vegetation, with some species associated with mosquito larvae.
Digamasellidae
Digamasellidae is a family of mesostigmatid mites containing 11 recognized genera. Members are primarily found in subcortical habitats, including bark beetle galleries and decaying wood. At least some species are nematophagous, feeding on nematodes. The family is distributed across Europe and has been recorded in association with pine bark beetles.
Zerconidae
Zerconidae is a family of mesostigmatid mites found primarily in soil and litter habitats across the Northern Hemisphere. The family includes approximately 20 genera and numerous species, with documented occurrences in North America, Europe, Turkey, and other regions. These mites have been collected from diverse habitats including boreal forests, temperate woodlands, reforested areas, felled sites, and forest canopies. Several genera are recognized, including Zercon, Prozercon, Mixozercon, Boreozercon, and Halozercon.
