Hi, Bugguide

This is a kind of millipede that I often see during the summer at this site. I was thinking that they were the species Harpaphe haydeniana, but then I learned that there were other similar xystodesmids to contend with in Oregon. Does anyone know if these are H. haydeniana or if they are something else?
