Aipysurus


Aipysurus is a genus of venomous snakes in the subfamily Hydrophiinae of the family Elapidae. Member species of the genus are found in warm seas from the Indian Ocean to the Pacific Ocean.

Taxonomy

The first description of the genus Aipysurus was published by Bernard Germain de Lacépède in 1804, accommodating his description of a new species found in Australian seas, Aipysurus laevis, the type species of the genus. The description was accompanied by an illustration of the new species.
The genus is one of a small group of the viviparous sea snakes with Emydocephalus, also mostly restricted to the seas between Timor, New Guinea and northern Australia.
The following species are recognised in the genus Aipysurus:

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Aipysurus.
A subspecies nominated in 1974 as A. laevis pooleorum was elevated in 1983 to full species status, as A. pooleorum, without explanation by the authors. The same revision also resurrected the species name Aipysurus jukesii, recognised as a synonym of Lacépède's Aipysurus laevis.
