Diagnosis: These mites have a palpal 

 thumb-claw complex and movable short 

 chelae which are stylet-like. The peritreme 

 is short and does not reach to the inner 

 base of the chelicerae. There are several 

 dorsal shields but no eyes and no differ- 

 entiated sensory setae on the propodo- 

 soma. The anus is terminal and there are 

 three pairs of genital suckers. Seven rod- 

 like and one conelike sensory setae appear 

 on tarsus i and two rodlike sensory setae 

 appear on tarsus ii. All tarsi have claws 

 but no pulvilli.

Discussion: This is a small (0.34 mm. long), raphignathid-like mite, 

 which is to be found in peach orchard soil in Georgia, United States. 

 The morphology and habitat indicate a predaceous life.
