Hydrozetidae
Hydrozetidae is a family of aquatic oribatid mites (water mites) within the order Oribatida, established by Grandjean in 1954. The family contains at least one genus, Hydrozetes, with at least 20 described species. These mites are distinguished by adaptations to freshwater habitats, including a reduced bothridium lacking a sensillus, monodactylous legs, and the absence of pteromorphae. Fossil evidence from the Late Paleocene of Canada demonstrates the family's ancient aquatic association with submerged vegetation.
