Idiopsar is a genus of Neotropical seed-eating birds in the tanager family Thraupidae.

Taxonomy and species list

The genus Idiopsar was introduced in 1867 by the American ornithologist John Cassin to accommodate the newly described short-tailed finch.[1] The name combines the Ancient Greek idios meaning "distinct" or "peculiar" with psar meaning "starling".[2]

This genus formerly contained a single species, the short-tailed finch. A molecular phylogenetic study of the tanager family, Thraupidae, published in 2014 found that the short-tailed finch was a member of a clade that contained three species assigned to other genera. In the reorganization of the generic boundaries, these three species were assigned to Idiopsar. The same genetic study found that Idiopsar is sister to the tit-like dacnis in the monospecific genus Xenodacnis.[3][4]

The genus contains four species.[4]

Red-backed sierra finch, Idiopsar dorsalis (former assigned to Phrygilus)
White-throated sierra finch, Idiopsar erythronotus (former assigned to Phrygilus)
White-winged diuca finch, Idiopsar speculifer (former assigned to Diuca)
Short-tailed finch, Idiopsar brachyurus
