G. R. Gray, 1867,
California and Mexico.
Closely related to O. poliocephala, of which formerly considered a race. A few cases of hybridization between the two in NW Jalisco were interpreted as proof of a narrow zone of intergradation in W Jalisco and W Colima (where intermediates were even considered a different race, lajuelae), but hybridization may have resulted from escapes of imported O. poliocephala; no other indication of contact between the two taxa, and existing evidence deemed insufficient for treating them as conspecific#R. Somewhat paler population of Sonora sometimes treated as race griseiceps, but probably the product of clinal variation#R. Monotypic.
W Mexico from S Sonora S to NW Jalisco.
