In North Africa, three species of large paleartic vipers have been recorded: Daboia mauritanica (Duméril & Bibron, 1848), D. deserti (Anderson, 1892) and Macrovipera lebetina transmediterranea Nilson & Andrén 1988. The latter has never been recorded accurately after its description, and it has never been included in any recent phylogenetic analysis. The taxonomic status of deserti is neither clear as a species, subspecies or just a morphological variation of D. mauritanica. Further research with genetic phylogenies with a wide sampling all over northwest Africa, is necessary to clarify the identity and taxonomic position of the taxa transmediterranea and deserti. Hopefully in a next future the population structure of this species complex will be better known.
