Taxonomy
The diuca finch was
formally described in 1782 by the Chilean naturalist
Juan Ignacio Molina under the
binomial nameFringilla diuca.[2] The specific epithet is from the Araucano names Diuca or Siuca for this species.[3] With the transfer of the
glacier finch (formerly white-winged diuca finch) to Idiopsar or Chionodacryon, the diuca finch is now the only member of the
genusDiuca, which was introduced in 1850 by the German naturalist
Ludwig Reichenbach.[4][5]
