Taxonomy and species list

The 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.[1] In the subsequent rearrangement to create monophyletic genera, the genus Geospizopsis was resurrected.[2][3] It had originally been introduced in 1856 by the French naturalist Charles Lucien Bonaparte with Passerculus geospizopsis Bonaparte, 1853 as the type species.[4] This taxon is now treated as a subspecies of the plumbeous sierra finch and has the trinomial name Geospizopsis unicolor geospizopsis.[3] The genus name combines Geospiza, a genus introduced by John Gould in 1837, with the Ancient Greek opsis meaning "appearance".[5]

The two species in the genus are:[3]
