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.

It contains these species:
 * Ashy-throated chlorospingus, C. canigularis
 * Yellow-throated chlorospingus, C. flavigularis
 * Common chlorospingus, C. flavopectus
 * Dusky-headed chlorospingus, C. (flavopectus) postocularis
 * White-fronted chlorospingus, C. (flavopectus) albifrons
 * Dwight's chlorospingus, C. (flavopectus) dwighti
 * Wetmore's chlorospingus, C. (flavopectus) wetmorei
 * Pirre chlorospingus, C. inornatus
 * Yellow-whiskered chlorospingus, C. parvirostris
 * Sooty-capped chlorospingus, C. pileatus
 * Dusky chlorospingus, C. semifuscus
 * Tacarcuna chlorospingus, C. tacarcunae

The taxonomy and systematics of the common bush tanager are under review; it appears to be a superspecies or even a complex of superspecies.
