Hueque or Chilihueque is a South American camelid variety or species that existed in central and south-central Chile in Pre-Hispanic and early colonial times. There are two main hypotheses on their status among South American camelids: the first one suggest that they are locally domesticated guanacos and the second that they are a variety of llamas brought from the north into south-central Chile. The alpaca has also been suggested as a possible identity. Chilihueques became extinct in the 16th or 17th century being replaced by European livestock. The causes of its extinction are unknown.
