This is a misapplied Name in North America:
North American collections previously labeled X. chrysenteron fall primarily into two species: one common in western North America described here as X. diffractus, and at least one undescribed species from eastern North America. These are not conspecific with the European X. chrysenteron, but rather appear more closely related to each other and to the European X. cisalpinus.
