Molecular phylogeny based on mtDNA sequences (12S–16S rRNA and cyt b genes) of Oligodon cattienensis, Oligodon cinereus and congeners showing the non-monophyly of both species. The low genetic divergence between O. cattienensis and O. cinereus populations from southern Indochina suggests the two taxa are conspecific.
