Taxonomy
[edit]The genusChloephagawas introduced in 1838 by the English naturalistThomas Campbell Eytonin hisA Monograph on the Anatidae, or Duck Tribe.[2]He designated thetype speciesasChloephaga magellanica.This isAnas magellanicaGmelin, JF1789, which is asynonymofAnas leucopteraGmelin, JF 1789.Anas leucopterais now considered as asubspeciesof theupland gooseChloephaga picta leucoptera.[3]The genus name comes from the combination of theAncient Greekkhloēmeaning "grass" with-phagosmeaning "-eating".[4]
Amolecular phylogeneticstudy by Mariana Bulgarella and collaborators published in 2014 found that theOrinoco goosein themonotypicgenusNeochem,was embedded in the genusChloephaga:[5]

Based on this result, some authorities place the Orinoco goose together with theAndean goosein the resurrected genusOressochen.[6][7][8]
A fossilized partialcoracoid(CTES-PZ 7797) of an indeterminateChloephagaspecies sharing some characters with the extantupland gooseis known from theupper PleistoceneToropí Formation(also called the Yupoí Formation) inCorrientes Province,Argentina, 700 kilometers further north than the northernmost present-day record of the genus.[9]
Species
[edit]The genus contains five species.[10]
