Diagnosis: These mites are reddish plant feeders of very small size 

 (from about 0.20 to 30 mm. in length) and of various shapes. A 

 suture may or may not separate the propodosoma and hysterosoma.

The skin may be striated or it may have a reticulated pattern. There 

 are two pairs of lenslike eyes, a few body setae, and no sensory setae 

 present. The palpi are cylindrical, small, and simple without thumb- 

 claw complex. The chelicerae are U-shaped, long, slender, needle-like, 

 and protrusible as in the Tetranychidae. A stylophore (mandibular 

 plate) is present. There are three or four pairs of legs in the adults. 

 All tarsi have claws, tenent hairs and pulvilli. Tarsi i and ii have rod- 

 like sensory setae. No genital suckers are present. The genital opening 

 is transverse as in the Eriophyidae.
