Diagnosis: These are medium-sized, oval 

 mites. The body is heavily clothed with setae 

 that give a furlike appearance on both the dor- 

 sal and ventral surfaces. The dorsal plate is 

 entire in the larvae, nymphs, and adults. Ven- 

 tral plates of males and females that in other 

 families have only a few setae may be covered 

 by setae in this family. All tarsi are provided 

 with pretarsi, caruncles, and claws. The trito- 

 sternum is present. The metapodal plates are 

 small and the stigmata with long, anteriorly 

 directed peritremes are present. The tectum is 

 tongue-like and has numerous irregular pro- 

 jections.
