|Taxonomic Notes:||This species has three subspecies: Hydrophis ornatus ornatus (Gray, 1942), Hydrophis ornatus godeffroyi Peters, 1873, and Hydrophis ornatus ocellatus Gray, 1849. The status of these subspecies is very uncertain, and the subspecies ocellatus is treated in this assessment as a separate distinct species (H. Cogger pers. comm. 2009).
H. lamberti has been considered a synonym of H. ornatus (Smith 1926).
This species has also been treated under the genus Chitulia.
