Similar Species

▪ Boa imperator (p. 315) is also a large constrictor with a cylindrical body, but it lacks visible labial pits or grooves.

Family Loxocemidae(Burrowing Python)

This family contains a single species, Loxocemus bicolor. It shares many characteristics with primitive boids, but its exact taxonomic placement has been controversial historically. Some authors considered this form to be the only representative of the family Pythonidae in the New World, which gave rise to the common name “burrowing python.” Until fairly recently, Loxocemus bicolor was included in the family Boidae, but it is now thought to be even more primitive than all contemporary boas. It has therefore been removed from that family and placed in its own.
