In Ecuador 3 subspecies of Boa constrictors are recognized. On West side of the Andes there are 2 subspecies native: Boa c. imperator towards North, while Boa c. longicauda towards South.
The third subspecies, true redtail boa (Boa c. constrictor) is native to the Eastern side of Andes, the Amazonian region. That latter is similar to Peruvian redtail boas (Boa c. constrictor) in morphology, which is not a wondrous phenomenon as the Amazonian Ecuador and Peru are one, connected geographical area.
Number of saddles are as low as 16-19, they are typically round shaped, with small peaks maybe. These saddles may or may not be connected. The posterior body and tail are orange colored.
This locality is considered as one of the biggest: Ecuadorian redtails can grow up to 3,5m (12 ft).
Ecuadorian redtail boas are very seldom in captivity. Ecuadorian goverment banned the export of animals a few decades ago, making it nearly impossible for this locality to become common in captivity.
Few years ago, there were some shipments of boas in the US that reportedly come from Ecuador, but later they turned out to be Peruvian redtails.
The one and only verified bloodline of Ecuadorian redtails come from a Dutch breeder who himself hand-collected the ancestors of his bloodline in Lago Agrio, Northeast Ecuador.
It was a fortunate the we could obtain an F1 couple from his very first offspring born in 2007. We can all honestly say that this is one of the most beautiful locality that we have ever had. Animals from this line are golden yellow, with high contrast, clean patterns, orange-red tails and a heavily spotted ventral surface.
Although their breeder labeled them as "Boa c. melanogaster", this is wrong for several reasons. First, this line is from Northeast Ecuador, not from Southeast Ecuador where Boa c. melanogaster was originally described from (Langhammer, 1983). Secondly, Boa c. melanogaster is not a valid taxa anymore, it is only a local form of Boa c. constrictor.
