Closely related to B. ruficapillus; structurally similar and has often been regarded as conspecific, but differences in both voice and plumage now generally considered sufficient to warrant treatment as separate species. Populations of Nicaragua and Costa Rica formerly separated as race costaricensis on grounds of larger size and fairly minor differences in coloration, but subsequently found to overlap in both aspects with birds from Panama and Colombia, now considered inseparable from semirufus. Two subspecies recognized.
