Thank you!
Actually, not anymore. The original study by Hynková et al. (2009), which suggested that taxonomic reclassification, has since been corroborated by additional evidence (see Suárez‐Atilano et al. 2014, Reynolds et al. 2013, and Reynolds et al. 2014) and has been adopted by a number of authors (e.g., Sunyer 2014, Solis et al. 2014, McCranie 2015).
As a result, there are two species--
Boa constrictor in South America east of the Andes, and
Boa imperator, which includes the populations in Central American and South America west of the Andes, such as the longtail boas of northern Peru. I have an article in the works that explains the results of some of those studies--I'll reference that when its up.
