[CA]: Al nord-oest d'àfrica apareixen un grup d'espècies d'origen sahelià en poblacions relictes i aparentment aïllades pel desert del Sàhara. No obstant això espècies molt tolerants a l‟aridesa podrien mantenir poblacions contínues, com podria ser el cas de Echis leucogaster segons indiquen els resultats de l'anàlisi genètica i els models bioclimàtics.
[EN]: In northwest Africa some species from Sahelian origin appear with relict populations and apparently isolated by the extreme aridity of the Sahara desert. However very tolerant to aridity species could maintain continuous populations as might be the case for Echis leucogaster as indicated by results from genetic analysis and bioclimatic models.
