This result calls into question the monophyly of cobras and underscores the uncertainty of the homology of the hood spreading behavior in cobras and mambas. The relationships of Dendroaspis, Ophiophagus, and Bungarus differed between the parsimony and likelihood analyses, suggesting that more work is necessary to resolve the relationships of these problematic taxa.[11] McDowell's findings in regard to the sister-group of Bungarus and the sea snakes (Hydrophiinae) family, propose that the kraits might just be a per-mutable clade between the elapidae "palatine-erectors" and the hydrophiinae "palatine draggers". Two genera within the subfamily Hydrophiinae in particular, support McDowell's hypothesis.
