Xenotyphlops is the only genus of the family Xenotyphlopidae, comprising two species. They are found in Madagascar.

Physical characteristics



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.

Geographic range



These snakes are found only from the type locality, which is "Madagascar", and the type specimens.
