分类信息

The bay-chested warbling finch was formally described in 1835 by the Finnish naturalist Alexander von Nordmann from a specimen collected in Brazil. He coined the binomial name Frigilla thoracica. This species was traditionally placed in the genus Poospiza. A molecular phylogenetic study published in 2014 found that the genus was polyphyletic. In the subsequent reorganisation the bay-chested warbling finch was moved to its own newly erected genus Castanozoster. The name combines the Ancient Greek καστανό meaning "chestnut" with ζωστήρ meaning "belt". The bay-chested warbling finch is monotypic: no subspecies are recognised.
