Taxonomía

The white-necklaced partridge was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other partridge like birds in the genus Tetrao and coined the binomial name Tetrao gingicus. Gmelin based his description "La perdrix de Gingi" that had been described by the French naturalist Pierre Sonnerat's in 1782 in his Voyage aux Indes orientales et a la Chine.Gmelin specified the type locality as "Gingi in Coromandel". This is an error, the species is found in southeast China. The white-necklaced partridge is now one of around twenty species placed in the genus Arborophila that was introduced in 1837 by Brian Houghton Hodgson. The genus name combines the Latin arbor, arboris meaning "tree" with the Ancient Greek philos meaning "-loving". The specific epithet gingicus is from the toponym "Gingi".<p>The white-necklaced partridge has two recognized subspecies:
