The Bolyeriidae are a family of snakes native to Mauritius and a few islands around it, especially Round Island. They also used to be found on the island of Mauritius, but were extirpated there due to human influence and foraging pigs in particular. These snakes used to be placed in the Boidae, but are now classed as a separate family. Two monotypic genera are recognized, but only a single species is extant. Bolyeriidae appear to be most closely related to the Asian genus Xenophidion.
Xenopeltis, the sunbeam snakes, are the sole genus of the monotypic family Xenopeltidae, the species of which are found in Southeast Asia. Sunbeam snakes are known for their highly iridescent scales. Three species are recognized, each one with no subspecies. Studies of DNA suggest that the xenopeltids are most closely related to the Mexican burrowing python and to the true pythons (Pythonidae).
The Calabar python is a species of non-venomous snake in the family Boidae. The species is endemic to West and Central Africa. It is the only species in its genus.

The amethystine python, also known as the scrub python or sanca permata in Indonesian, is a species of non-venomous snake in the family Pythonidae. The species is found in Indonesia and Papua New Guinea. Popular among reptile enthusiasts, and noted for its coloration and size, it is one of the largest snakes in the world, as measured either by length or weight, and is the largest native snake in Papua New Guinea. Until 2000, the larger S. kinghorni was generally considered a subspecies of S. amethistina, and this change of classification has still not been universally reflected in literature. Because of this issue, S. amethistina has often been described as the largest snake in Australia, but this is not accurate since under the current classification, this species does not occur in Australia.
Tropidophis, common name Caribbean dwarf boas, wood snakes or West Indian wood snakes, is a genus of dwarf boas endemic to the West Indies and South America. Currently, either 17 or 33 species are recognized, depending on the authority.

Two subspecies are recognized, including the nominate subspecies, described here. Candoia bibroni is one of the most isolated and far-removed species of boid snakes on earth, as the majority of boa species are found in the Americas and the Caribbean, or, in the case of the terrestrial sand boas, in Africa and Eurasia.
Trachyboa gularis, commonly known as the Ecuadorian eyelash boa, is a species of nonvenomous snake in the family Tropidophiidae. It is endemic to Ecuador, and is only known from an area where suitable habitat has been almost completely destroyed. Recent confirmed records are also lacking, and the IUCN has concluded that Trachyboa gularis is a possibly extinct species.
