Diagnosis: These are small, red 

 mites from 0.350 to 0.500 mm. 

 long (not including the gnathos- 

 oma which is long and conelike). 

 A suture separating the propo- 

 dosoma from the hysterosoma is 

 present. The integument is soft, 

 finely striated, punctate in spots, 

 and in many cases has extensive 

 plates. There are four distinct 

 sensory setae on propodosoma. 

 Eyes may or may not be present. 

 The legs have six movable seg- 

 ments; all tarsi have claws and 

 pulvillus. The palpi are used for 

 grasping and are large, pincer- 

 like, and usually have apophyses 

 and strong spines on the inner 

 side. The palpal end segment is 



clawlike, and the chelicerae are elongated with a very small, distal, 

 sickle-like digitus mobilis. Two pairs of genital suckers are present.
