Xenotyphlops is the only genus of the family Xenotyphlopidae, comprising two species. They are found in Madagascar.
Members of this genus are distinguishable externally from the Typhlopidae by possessing a greatly enlarged and nearly circular rostral shield. This shield is nearly vertical in a lateral aspect, as a result the two species have a "bull-dozer" appearance. Xenotyphlops species are internally unique in that (1) they lack a tracheal and (2) possess an unexpanded tracheal membrane.
These snakes are found only from the type locality, which is "Madagascar", and the type specimens.
