Taxonomy and species list
editThe two species now placed in Geospizopsis were formerly placed in the genus Phrygilus. A molecular phylogenetic study of the tanagers published in 2014 found that Phrygilus was polyphyletic.[2] In the subsequent rearrangement to create monophyletic genera, the genus Geospizopsis was resurrected.[3][4] It had originally been introduced in 1856 by the French naturalist Charles Lucien Bonaparte with Passerculus geospizopsis Bonaparte, 1853 as the type species.[5] This taxon is now treated as a subspecies of the plumbeous sierra finch and has the trinomial name Geospizopsis unicolor geospizopsis.[4] The genus name combines Geospiza, a genus introduced by John Gould in 1837, with the Ancient Greek opsis meaning "appearance".[6]
The two species in the genus are:[4]
| Male | Female | Common Name | Scientific name | Distribution |
|---|---|---|---|---|
| |
 |
Plumbeous sierra finch | Geospizopsis unicolor | Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela. |
 |
Ash-breasted sierra finch | Geospizopsis plebejus | Argentina, Bolivia, Chile, Ecuador, and Peru. |
