Subspecies
Has recently been proposed that this species be placed in genus Spinus or Sporagra, and revision may be justifiable as phylogenetic analysis indicates that South American siskins are only distantly related to the two Holarctic species (Eurasian Siskin (Spinus spinus) and Pine Siskin (Spinus pinus)), but comprehensive review of all species currently included within present genus is required in order to determine true relationships.
The following 2 subspecies are recognised:
xanthogastra (Du Bus de Gisignies, 1855) - Mountains of Costa Rica and western Panama (western Chiriqui), Colombia, north-western and northern Venezuela and north-western and south-western Ecuador.
stejnegeri (Sharpe, 1888) - Extreme south-eastern Peru (eastern Puno) and western Bolivia.
