Body Segmentation

Some enarthronote oribatid mites have 1-3 notogastral scissures that are associated with body flexion and / or erectile setae, but probably do not represent remnants of primary segmentation.  Some prostigmatic mites also appear to be segmented, especially those in the Heterostigmata (Tarsonemina).  Mites that appear to be segmented are well sclerotized and have a series of plates dorsally, but these divisions do not extend ventrally.  True segmentation is recognizable in some early derivative Endeostigmata, but these a mites are soft-bodied and unlikely to be seen as segmented except by specialists.
