Sometimes regarded as conspecific with C. yucatanicus, but differs significantly in plumage, voice, behaviour and nest form; genetic data also fail to support this suggestion#R. USA and N Mexican population sometimes referred to as race anthonyi, but name couesi has priority. Race purus sometimes subsumed within affinis; distinctiveness of race seri not upheld by molecular study#R and wider research found evidence of just two separate DNA lineages within the species#R. Eight subspecies recognized.
