Disteira is a genus of sea snakes.

History

Disteira was characterized by Boulenger in 1890 as having grooved maxillary teeth following the first pair of poison fangs.[1] However, later dental examination under more powerful magnification found all sea snakes have grooves in their teeth,[2] some deep and wide channels visible to the naked eye, others only at the base of the tooth and requiring magnification to observe.[3] In light of those new findings, Disteira and Hydrophis were merged until McDowell resurrected Disteira as a separate genus in 1972 to accommodate new species.[4] He redefined Disteira as possessing a broad dorsal portion of the venom gland muscle called the Oxyuranus pattern.[5]

Although McDowell rolled the monotypic genus Astrotia - which contains only Stoke's seasnake - into Disteira, that classification is not widely adopted.[5]
