Other common names:
longicauda: Long-tailed Boa
mexicana: Mexican Common Boa
ortonii: Peruvian Boa
sabogae: Saboga Boa
Remarks:
Previously considered a subspecies of constrictor (e.g., Forcart 1951).
Formerly included sigma, to which species most West Mexican records of imperator refer.
Revalidated as a separate species by Reynolds, Niemiller & Revell (2014).
Based on the distribution maps in Card, Schield, Adams, Corbin, Perry, Andrew, Pasquesi, Smith, Jezkova, Boback, Booth & Castoe (2016),
both imperator and sigma appear to occur in Guerrero, Oaxaca, and Puebla. Older records from these states may therefore represent either of the two species.
