Remarks
Doug Yanega (U.C. Riverside Entomology Research Museum) writes concerning ID for this wasp:


"It appears to be Euodynerus annulatus imperialis, a subspecies
restricted to dry areas from Anza-Borrego across to Parker, Az. ALL
of the "subspecies" of annulatus, including this one, seem to be
highly variable in coloration, to the point of no two being
absolutely identical."
