It has been replaced west of the Andes (and in Central America) by the closely related thick-billed seed finch (S. funerea). The two have often been considered conspecific as the lesser seed-finch, using the older scientific name Oryzoborus angolensis. == Taxonomy == The chestnut-bellied seed finch was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae under the binomial name Loxia angolensis.

The chestnut-bellied seed finch does not occur there and the type locality is now designated as eastern Brazil. The chestnut-bellied seed finch and the thick-billed seed finch were formerly considered conspecific and together had the English name "lesser seed-finch". Both species were formerly placed in the…
