The Bolyeriidae are a family[2] 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.[3] 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.[2] Bolyeriidae appear to be most closely related to the Asian genus Xenophidion.[4]

Geographic range

Found in Mauritius.[1]
Genera

Genus[2]	Taxon author[2]	Species[2]	Common name	Geographic range[1]

Casarea	Gray, 1842	1	Round Island ground boa[6]	Mauritius.

T) Type genus.[1]

Both of these monotypic genera once inhabited Mauritius and/or a number of islands around it. However, Bolyeria hasn't been reported since 1975 and is believed to be extinct, while Casarea is known to survive only on Round Island.[1]
