The Amazon Basin emerald tree boa (Corallus batesii) is a species of boa found in the tropical rainforests of South America. This species has been revalidated from the synonymy of Corallus caninus by Henderson and colleagues in 2009.
English naturalist John Edward Gray originally described this species as Chrysenis batesii in 1860. The specific name, batesii, is in honor of Henry Walter Bates, an English naturalist and explorer, for whom Batesian mimicry is also named.
The Amazon Basin emerald tree boa has a yellow belly. The dorsum is dark green with an enamel-white vertebral stripe, which has confluent partial crossbars, often bordered by some black spots. Corallus batesii differs from C. caninus by the shape and the number of scales across the snout. Also, C. batesii is bigger than C. caninus, growing to a total length (including tail) approaching 9 feet (2.7 m).
The "Basin species", as the common name suggests, is only found in the basin of the Amazon River, in southern Suriname, southern Venezuela to Colombia, Peru and Brazil and in the surrounding jungles of the Amazon River.
