Asemospiza is a genus of South American birds in the tanager family Thraupidae.
Taxonomy and species list These species were formerly placed in the genus Tiaris. A molecular phylogenetic study published in 2014 found that Tiaris was polyphyletic. In the resulting reorganization to create monophyletic genera, these two species were assigned to a new genus Asemospiza with the sooty grassquit as the type species. The name combines the Ancient Greek ἄσημος/asēmos meaning "without marks" with σπίζα/spiza meaning "finch". These two species are in the subfamily Coerebinae and form a sister clade to the Darwin's finches.
