Subspecies
No subspecies.
May form a superspecies with Andean Siskin (Spinus spinescens). Recent phylogenetic analysis indicates that South American siskins are only distantly related to the two Holarctic ones, but comprehensive review of all species currently included within present genus is required in order to determine true relationships.
