DIUCA

(Thraupidae; Ϯ Common Diucafinch D. diuca) Specific name Fringilla diuca Molina, 1782. Reichenbach's 1850, plate LXXVIII, labelled Passerinae: Pyrrhulinae Coccothraustinae, shows a variety of heavy-billed finches, including Diuca, Crithagra, Lamprospiza, Linurgus, and Caryothraustes. "Diuca, Reichenb. (Euspina, p. Gr.)  1. FRINGILLA diuca, Molina. (Emberiza diuca, Orb. 1838. Euspiza diuca, Gr.) Kittl. Mem. Ac. Petersb. 1831. t. 11. Voy. Favor. t. 17. - Mag. Zool. 1836. t. 9. et 1837. t. 69.  ex Chili, Patagonia." (Bonaparte 1850); "Diuca Reichenbach, 1850, Av. Syst. Nat., pl. 78. Type, by subsequent designation (G. R. Gray, 1855, Cat. Genera Subgenera Birds, p. 79), Emberiza speculifera Lafresnaye and d'Orbigny." (Paynter in Peters 1970, XIII, 118): however, Reichenbach's plate shows the features of the Common Diucafinch, which may be considered the type by tautonymy (see Chionodacryon).
Synon. Hedyglossa.
