Major Body Regions

In many mites only one body region - the idiosoma - is easily distinguished. 

Scale insects, the immature stages of white flies, and some parasitic mites are often blob-like and even the remnants of legs can be difficult to distinguish.  Tardigrades have a cephalic segment, but no distinct head and lobopods, rather than segmented legs.

Allow Misinterpretations: Pseudoscorpions and opilionids have broad prosomal-opisthosomal junctures and could be confused with mites.
