Races form three monotypic groups based largely on differences in plumages of males (those of females are generally very similar). Original spelling “lopezi” was emended by the describer himself later in same year to “lopesi”, as intended to honour the original collector, but this is an unjustified emendation, unsupported by any internal evidence. Three subspecies recognized.
