It is only known from the cloud forests of Sierra Madre del Sur of central Guerrero. It is phenotypically identical to the chesnut-capped brush finch (A. brunneinucha), which has a much wider range throughout the Americas and reaches its northern limit in central Mexico. However, genetic differences in mitochondrial DNA indicate a heavy divergence between A. kuehnerii and A. brunneinucha, and indicate that while both species look identical, the closest relative of A. kuehnerii is actually the green-striped brush finch (A. virenticeps), another Mexican endemic. The physical similarities between A. kuehnerii and A. brunneinucha despite the relation to A virenticeps are likely due to A. kuehnerii (but not A. virenticeps) retaining an ancestral phenotype similar to that of the A. brunneinucha species complex.[1][2]
The Guerrero brushfinch is not included on the online list of world birds maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee.[3] Recognition of the species was considered but rejected by the American Ornithologists' Union.[4]
