Idiopsar is agenus ofNeotropical seed-eating birds in the tanager familyThraupidae.
The genusIdiopsar was introduced in 1867 by the American ornithologistJohn Cassin to accommodate the newly describedboulder finch.[1] The name combines theAncient Greekidios meaning "distinct" or "peculiar" withpsar meaning "starling".[2]
This genus formerly contained a single species, the boulder finch. Amolecular phylogenetic study of the tanager family (Thraupidae) published in 2014 found that the boulder finch was a member of aclade that contained three species assigned to other genera. In the ensuing reorganization of generic boundaries, these three species were assigned toIdiopsar. The same genetic study found thatIdiopsar issister to thetit-like dacnis in themonospecific genusXenodacnis.[3][4]
The genus contains four species.[4]
