Death adders
Acanthophis - Daudin, 1803

Pronunciation: AK-anth-OH-fiss
Etymology: 'spine snake', refering to the spine at the tip of the tail.

Taxonomic notes:

The taxonomy of the members of this genus is currently unclear. Molecular evidence suggests a number of groups:1

  • Barkly Tablelands, Mt Isa, northern Northern Territory, southeastern Irian Jaya - the 'Acanthophis rugosus' complex, possibly comprising two species:
    • Acanthophis rugosus - 'hill adders'
    • Acanthophis hawkei - 'floodplain', Fogg Dam, Barkly Tableland

  • north-eastern Queensland - north-eastern death adder (Acanthophis praelongus)
  • Pilbara region and surrounds of Western Australia - Pilbara death adder (Acanthophis wellsi)
  • central Australia, west to nearly surround the Pilbara region - desert death adder (Acanthophis pyrrhus)
  • from Perth in the west, south along the coast, up the east coast to about Cairns - common death adder (Acanthophis antarcticus)

There does not appear to be a clear separation between the common death adder (Acanthophis antarcticus) and the north-east Queensland north-eastern death adder (Acanthophis praelongus).

The name Acanthophis hawkei (named for former Prime Minister Bob Hawke) is available should specimens from the Barkly Tableland region be split into a separate species.2 As of May 2012, the Federal Government lists A. hawkei as vulnerable.

Pending a formal systematic review, the traditional arrangement of species is presented here.

Notes: Around six species found through Australasia, with four or five endemic Australian species.

Smallest Australian species: Kimberley death adder (Acanthophis cryptamydros) at 43 cm
