Taxonomy

The grey-headed tanager was formally described in 1825 by the German naturalist Johann Baptist von Spix under the binomial name Tanagra penicillata.[2] Spix did not specify a type locality by this was later designated as Fonte Boa in the Brazilian state of Amazonas.[3] The grey-headed tanager is now the only species placed in the genus Eucometis that was introduced by the English zoologist Philip Sclater in 1856.[3][4][5] The genus name is derived from Ancient Greek eukomēs meaning "with lovely hair". The specific epithet penicillata is from the Latin diminutive of peniculus meaning "brush".[6]

Within the Thraupidae, the grey-headed tanager is a member of the subfamily Tachyphoninae and is the sister species to the black-goggled tanager in the monospecific genus Trichothraupis.[7]

Seven subspecies are recognised:[5]

  • E. p. pallida Berlepsch, 1888 – southeast Mexico to Honduras
  • E. p. spodocephalus (Bonaparte, 1853) – Nicaragua and north Costa Rica
  • E. p. stictothorax Berlepsch, 1888 – west-central Costa Rica to west Panama
  • E. p. cristata (Du Bus de Gisignies, 1855) – east Panama, north Colombia and northwest Venezuela
  • E. p. affinis Berlepsch, 1888 – north Venezuela
  • E. p. penicillata (Spix, 1825) – southeast Colombia, east Ecuador and east Peru east through the Guianas and north Brazil
  • E. p. albicollis (d'Orbigny & Lafresnaye, 1837) – Bolivia and Paraguay through central Brazil
