Subspecies
Forms a superspecies with Greyish Piculet (Picumnus granadensis), and possibly conspecific.
Proposed subspecies panamensis (eastern Panama to extreme north-western Colombia) considered insufficiently distinct from flavotinctus, and malleolus (northern Colombia from northern Sucre south to upper R Sinú and southern Bolivár) not distinguishable from nominate. In past, subspecies eisenmanni was referred to as subspecies "perijanus", but this name is preoccupied by a subspecies of Chestnut Piculet (Picumnus cinnamomeus).
flavotinctus Ridgway, 1889 - Costa Rica, Panama and extreme north-western Colombia (northern Chocó).
eisenmanni Phelps Jr & Aveledo, 1966 - Sierra de Perijá in extreme north-western Venezuela, possibly also in adjacent northern Colombia.
olivaceus Lafresnaye, 1845 - Western Colombia from northern Sucre (Serranía de San Jacinto) south to upper R Sinú and southern Bolívar, southern in central Andes to lower Cauca Valley and in eastern Andes to Huila.
