Diagnosis: These are small to medium-sized mites that are unar- 

 mored and have striated skin and peritremes. The chelicerae are mi- 

 nute and stylet-like. The palpi are simple, minute, and not used for 

 grasping; they may or may not have a claw and if a thumb is present

it is hard to see. The first pair of legs may be modified for grasping 

 hairs; the other legs have one or two claws. The male genital opening 

 may be dorsal. This is a rather heterogeneous group of mites and may 

 be further separated upon study. Harpirhynchus, Ophioptes, Picobia, 

 Psorergates, and Syringophilus may form a distinct family intermediate 

 between the Myobidiidae and Cheyletidae but probably closer to the 

 latter.
