Fringilla fuliginosa Wied, 1831, currently recognized as Tiaris fuliginosus.  Included species. Asemospiza fuliginosa (Wied, 1831) and A. obscura (d'Orbigny & Lafresnaye, 1837), the latter currently recognized as T. obscurus.   ...  Etymology. Asemospiza is formed from the Greek ασημος, "unmarked," in reference to the unstreaked drab plumage of the two component species, and Greek σπιζα, the chaffinch Fringilla coelebs, commonly used in ornithology in the coining of names of finch-like birds.  Its gender is feminine, in accord with Greek grammar."
