Xenopeltis

Xenopeltis is the genus of sunbeam snakes,[2] of the monotypic family Xenopeltidae, the species of which are found in Southeast Asia. Sunbeam snakes are known for their highly iridescent scales. Currently, two species are recognized.[3] Studies of DNA suggest that the xenopeltids are most closely related to the Mexican burrowing python, Loxocemus bicolor, and to the true pythons of Pythonidae.[4][5]
