Dusky Bush-tanager (Chlorospingus semifuscus) - HBW 16, p. 304
French: Chlorospin ombré
Spanish: Clorospingo Oscuro
Other common names: Dusky-bellied Bush-tanager
Taxonomy: Chlorospingus semifuscus P. L. Sclater and Salvin, 1873, near Quito, Ecuador.
Recent molecular-genetic studies indicate that this genus and Nesospingus, Spindalis and Phaenicophilus form a monophyletic clade that is sister to several New World warbler (Parulidae) genera (including Dendroica, Basileuterus and Vermivora), and are not closely related to other genera of present family. More recent evidence suggests that Chlorospingus is closest to genus Arremonops in family Emberizidae. Two subspecies recognized.
