Specific limits and distributions are defined. An analysis of geographical variation provides a consistent basis for the recognition of subspecies. Four monotypic species (venezuelensis, apicalis, semirufus, and magnirostris) and seven polytypic species (tuberculifer, swainsoni, phaeocephalus, cephalotes, panamensis, ferox, and tyrannulus), with 20 subspecies, are admitted. No new forms are described. Diagnoses and keys are based on morphological and vocal characters. Data on vocal repertoires, breeding, and the timing of the annual cycle are summarized for each species.
