Euzerconidae
Euzerconidae is a of mesostigmatid mites in the order Mesostigmata, suborder Trigynaspida. The family comprises twelve and approximately 20 recognized . Members of this family have been documented in association with passalid beetles (Coleoptera: Passalidae), suggesting a phoretic or parasitic relationship with these wood-decaying beetles. The family has a broad geographic distribution including the Americas, Africa, and Asia, though individual species ranges appear restricted.

Habitat
Associated with passalid beetles (Coleoptera: Passalidae), which inhabit decaying wood in forest . The mite- association suggests specialization for this microhabitat, though specific microhabitat requirements within beetle galleries or on beetle bodies remain undocumented for most .
Distribution
Documented from the Americas (Brazil, Colombia, Trinidad), Africa (Ghana), and Asia (China). -level distributions appear restricted; for example, Alloeuzercon seemani is known only from China, Euzerconiella ghanae from Ghana, and several Euzercon species from Brazil.

Taxonomic History
The has undergone substantial revision, with many erected by R.C. Funk in 1980 (Euzerconoides, Karkinoeuzercon, Microeuzercon, Neoeuzercon, Paraeuzercon, Pseudoeuzercon, Synaptoeuzercon, Trichotoeuzercon) and by Hunter & Rosario in 1989 (Etazercon, Trinizercon). The type genus Euzercon was established by Berlese in 1888.
