Chrysomitris xanthogastra

, 1855,

Ocaña, Colombia

.

Comprehensive molecular phylogeny of South American siskins recovered this species as sister to race alleni of S. magellanicus#R. Speed of songs of races have been contrasted, with stejnegeri being slower#R, but nominate occasionally also sings a simple song with well-separated notes; thus differences minor#R. Two subspecies recognized.
