A [[Phylogeny|phylogenetic]] analysis of [[mitochondrial DNA]] showed that specimens from [[Surat Thani Province]] and [[Nakhon Si Thammarat Province]]s in southern Thailand form a deeply [[Genetic divergence|genetically divergent]] [[clade]] from those in northern Thailand, which grouped with specimens from Myanmar and Guangdong in southern China.<ref>{{Cite journal |doi=10.5372/1905-7415.0802.289 |title=Phylogenetic analysis of the king cobra, ''Ophiophagus hannah'' in Thailand based on mitochondrial DNA sequences |journal=Asian Biomedicine |volume=8 |issue=2 |pages=269–274 |year=2014|last1=Suntrarachun |first1=S. |last2=Chanhome |first2=L. |last3=Sumontha |first3=M.|doi-access=free}}</ref>
