Naja incertae sedis

Three of the four currently recognized extinct cobra species, † Naja antiqua Rage, 1976, † Naja iberica Szyndlar, 1985, and † Naja robusta Meylan, 1987, cannot be allocated to any subgenus with confidence, as identifying synapomorphies are lacking (Rage, 1976; Szyndlar, 1985; Meylan, 1987). They are therefore placed in Naja incertae sedis .
