Comments

  • Mesostigmata in these two suborders are not members of the suborder Monogynaspida and are not keyed out here. More about them can be found in the key Major mite taxa.

  • Members of the Sejida are predators usually associated with woody habitats (e.g., tree holes, suspended soils, rotting logs) or leaf litter. Many have a phoretic deutonymphal stage that hitches rides in beetles or flies.

  • Most members of the Trigynaspida are associated with insects (especially beetles), millipedes or centipedes. A few are found on reptiles and some families are comprised of free-living mites, mostly in tropical to subtropical forest litter.
