NEW SPECIES: Boa sigma
An in-depth look at boa constrictor genetics has revealed some interesting results, including the existence of a third species found along the Pacific coast of Mexico, west of the Isthmus of Tehuantepec: Boa sigma. The study also found that the dwarfism found in certain Central American island populations evolved independently from each other.
The research is available here: http://www.herp.mx/pubs/2016-Card-et-al-Boa.pdf
The specimen of Boa sigma shown here is from the western state of Colima.
