  phylogenetic justification
Assignment of to the genus Naja is based on an anteroposteriorly short and laterally recurved maxilla with two large anterior venom fangs and two solid posterior teeth (Hoffstetter, 1939; Bogert, 1943) and fenestra vestibuli completely or nearly completely bounded within the otooccipital (Hoffstetter, 1939; Szyndlar and Rage, 1990).
