Boulengerina is a genus of elapid snakes known commonly as water cobras, so named because of their semi-aquatic nature. The genus has two recognized species, which are found in central and southern Africa. Some recent molecular studies have suggested that the genus Boulengerina should be synonymised with Naja, because the water cobras are closely related to some species of Naja
