Diagnosis: The analgesids are feather 

 mites. As a rule, the females lack plates 

 on the hysterosoma (exception Mesal- 

 ges) . They have an undivided, rounded, 

 posterior margin. Legs i and ii usually 

 have latero-ventral, triangular, cufflike 

 projections. Legs iii or iv, or both, of 

 the male are more developed than the 

 others and often are highly developed.
