Subspecies
No subspecies.
Pteroptochos tarnii (Sibley and Monroe 1990, 1993) has been split into Huet-huet (Pteroptochos tarnii) and Chestnut-throated Huet-huet (Pteroptochos castaneus) following SACC (2005).
Forms a superspecies with Chestnut-throated Huet-huet (Pteroptochos castaneus), and formerly considered conspecific. The two are geographically separated in western Argentina (Neuquén) by a distance of over 200 km. Recent studies have shown, however, that, despite earlier theories, the upper R Bío Bío is not an effective barrier to dispersal, suggesting that the two taxa have been in contact several times during fluctuating climatic conditions.
