Taxonomy

edit

The diuca finch was formally described in 1782 by the Chilean naturalist Juan Ignacio Molina under the binomial name Fringilla 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 genus Diuca, which was introduced in 1850 by the German naturalist Ludwig Reichenbach.[4][5]

Four subspecies are recognised:[5]

  • D. d. crassirostris Hellmayr, 1932 – north-central Chile, south Bolivia and north Argentina
  • D. d. diuca (Molina, 1782) – central, south-central Chile and west Argentina
  • D. d. chiloensis Philippi Bañados & Peña, 1964 – Chiloé Island (off southern Chile)
  • D. d. minor Bonaparte, 1850 – central, south Argentina and south Chile
