Subspecies
No subspecies.
Genus sometimes subsumed in Agelaius. Molecular data indicate close affinity with Pseudoleistes and more distant relationship to Chrysomus, these findings supported by behavioural data. In morphology resembles more the last two genera, but with rather stout tarsometatarsus and thin bill. Form Icterus xantholemus, based on a single speciment from southern Brazil but erroneously published as from Ecuador, has been shown to be a synonym of present species.
