Mites

Mites
Virginia Beach, Virginia, USA
February 15, 2008
These tiny mites were attached to the underside of a Horned Passalus beetle that I was shooting. Just curious as to an ID for them.

Actually, there are now 18 species of mites known as obligate associates of Odontotaenius disjunctus. I agree that the two mites posterior to coxae I are probably Diarthrophallus quercus. The large mites in front of coxae I are in the family Macrochelidae, genus Macrocheles. 3 species are described from O. disjunctus. The small mites just above the keel are one of the 3 species of Uropodidae known in this system, and the very small, round mites just below the keel are undescribed species of Astigmata, either Acaridae or Histiostomatidae. - Barry OConnor

 
Thank you
For helping with the identification of these mites. I only wish the images were better. I am now set up to provide improved images of these small mites and will do so if I find more at a later date.

Several possibilites
Pearse et al. (1936), working in North Carolina, found 12 species of mites associated with Odontotaenius disjunctus. They present a table of the seasonal variation of mite species found, and the most common external mites in February were 3 species of Uroobovella. The top group of mites might be one of those species.

The two mites near the bottom with long hairs appear to be Uroseius quercus based on the illustrations presented in the paper.

Disclaimer: I know next to nothing about mites, and am just basing this on information from the paper below.

Thanks Brad...
I added another image.
