Is it a Mite?

Mites are so small, morphologically diverse, and often bizarrely modified, that even specialists occasionally made an incorrect first diagnosis.  There is even a case in the literature of a mite having been misdescribed as a new species of spider.  

This key is provided in the hopes that if a suspicious looking tiny arthropod is encountered in an inspection, it can quickly be determined if it is a mite.  A second, objective of this key is to begin introducing and explaining the terminology that will be used in my other mites keys.  Terms are explained in the character state notes and images and in a separate glossary.

A Key to the Genera of Endeostigmata and Sphaerolichida

This is a key to the genera of primitive acariform mite groups Endeostigmata and Sphaerolichida written and compiled by Dr David Evans Walter of Colorado State University and the University of Alberta with the assistance of Dr Heather Proctor of the University of Alberta.

Endeostigmatans are common in many habitats, but seem to reach their highest abundances in extreme habitats such as deserts, beaches, and polar regions. As far as is known, these mites are fungivores, algivores and predators on small invertebrates such as nematodes, tardigrades, and mites.  None are considered economically important pests.  They are most likely to be intercepted in goods containing soil, especially dry soils including sand, lichens, mosses or other materials associated with dry or otherwise extreme habitats, including anthropogenic accumulations of dust.

Orders, Suborders & Cohorts of Mites in Soil

The taxonomy of mites is in a state of flux.  About two dozen major taxa of mites living in soil are currently recognised and variously designated as superorders, orders, suborders (cohorts) or infraorders.  This key allows identification of these groups and also can be used by beginners for determining which of the more advanced family keys are appropriate.
