Chlorospingus

Chlorospingus is a genus of perching birds, the bush tanagers, traditionally placed in the tanager family (Thraupidae). More recent studies which suggest they are closely related to the genus Arremonops in the Passerellidae (American sparrows). As of July, 2017, the American Ornithological Society assigns the genus to the new family Passerellidae, which contains the New World sparrows.

==Taxonomy== The genus Chlorospingus was introduced in 1851 by the German ornithologist Jean Cabanis to accommodate a single species, Chlorospingus leucophrys Cabanis. This scientific name is a junior synonym of Arremon ophthalmicus Du Busde Gisignies, 1847, which is now treated as a subspecies of Chlorospingus flavopectus, the common chlorospingus. The genus name Chlorospingus combined the Ancient Greek χλωρος/khlōros meaning "green" with σπινος/spinos a small bird found in Greece, perhaps a chaffinch.
