I think you nailed it, @isaj, many thanks! @nmcnear, this is just a few pages away from Chrysomphalina in Siegel & Schwarz (2016), so you were on the right track if this is correct (I overlooked it due to the blue color in the photo). Habitat of disturbed soil with moss also fits well, since this was at the edge of the parking area.
