The Santa Marta tinamou, Crypturellus erythropus idoneus, is a subspecies of tinamou that was recognized as a species by most authorities until 2006. It is found in northern South America.
Crypturellus is formed from three Latin or Greek words: kruptos meaning covered or hidden, oura meaning tail, and ellus meaning diminutive. Therefore, Crypturellus means small hidden tail.
